摘要： PURPOSE:To ensure the color density is uniform, image quality free of color defects or voids in dots can be obtained, little electrostatic charge is generated at the time of printing and curling does not occur after printing, by providing a highly elastic intermediate layer between a photographic printing paper and a dyeable resin layer. CONSTITUTION:The image-receiving paper for thermal transfer comprises the printing paper 1, the intermediate layer 2 and the dyeable resin layer 3. The intermediate layer is formed of a material rich in elasticity and capable of easily achieving uniform close contact of the layers 3, 4 under a pressure exerted by a thermal head, and is generally provided by using a substance having rubber elasticity. Particularly, a substance having a Young's modulus of 10 -10 dyn/ cm , preferably, 5X10 -5X10 dyn/cm is suitable. A covalent bond crosslinked type elastomer generally called vulcanized rubber, a thermoplastic elastomer which is plasticized at high temperature so that it can be molded or formed by plastic-processing machines, and a thermoplastic having a low modulus of elasticity can be used as a substance for forming the intermediate layer.

摘要： PURPOSE:To obtain extremely favorable images having a high and uniform color density and free of color missing or void in each dot, by providing a highly elastic intermediate layer between a printing film and a dyeable resin layer. CONSTITUTION:The elastic intermediate layer is provided between the printing film 1 and the dyeable resin layer 3. As the rubber elastic intermediate layer, a material rich in elasticity and capable of bringing the layer 3 and an ink layer 4 into close contact with each other easily and uniformly under the pressure of a thermal head 6 is used. Particularly, the layer 2 consists of a substance having a Young's modulus of 10 -10 dyn/cm . If the Young's modulus is less than 10 dyn/cm , the intermediate layer 2 itself is unrecoverably distorted under the heat and pressure applied by the thermal head 6 at the time of printing, whereby the surface of the OHP film 1 is rugged, leading to a marked reduction in gloss. On the other hand, if the Young's modulus is more than 10 dyn/cm , sufficient close contact can not be obtained between the resin layer 3 and the ink layer 4 under the pressure of the head 6, so that color density becomes low and nonuniform.

摘要： PURPOSE:To enable smooth printing free of fusing or abnormal transfer and obtain an image free of contamination or formation of voids due to friction with a thermal head and having excellent transparency and sufficient color density, by providing a specified thin film of a silicone resin by curing a curable- type silicone resin in a three-dimensional form through cross-linking. CONSTITUTION:The OHP film comprises a printing film 1, a dyeable resin layer 2 and a cured silicone resin layer 3. The cured silicone resin is obtained by bringing a silicone resin into an addition reaction with polyorganosiloxane by heating in the presence of a catalyst such as chloroplatinic acid to obtain a three-dimensional structure, or by bringing the silicone resin into an addition reaction by irradiation with UV rays to obtain a three-dimensional structure. The cured silicone layer is obtained by a method wherein a silicone resin is mixed with a catalyst for curing, the mixture is diluted with an organic solvent to an appropriate concentration, the diluted mixture is applied to the resin layer 2, is dried, and is cured by heating at 100-150 deg.C for about 1-5min, or by irradiating it with UV ray from a mercury lamp with a dose of ordinarily 100mj/cm . The thickness of the film is 0.03-0.30g/m as dried weight.

摘要： PURPOSE:To simplify sticking work of thermal transfer image receiving material, by previously providing cutting lines of predetermined length to allow easily separation into predetermined size after printing. CONSTITUTION:Thermal transfer image receiving material 1 is lapped over a thermal transfer sheet having a thermal transfer coloring layer on a substrate 4, then they are heated selectively by means of a thermal head to form an image. Thereafter, they are cut along cutting lines 2 and stuck on a target object so as to form an image on the object. Cutting lines 2 may be perforated through the thermal transfer image receiving material 1 by means of common means such as laser beam or may be half cut in the substrate 4. A separator may be provided on an adhesive layer 5 of the thermal transfer image receiving material 1, and in this case, the cutting lines 2 may penetrate through the substrate 4.

摘要： PURPOSE:To obtain an OHP film free of possibility of positional errors at the time of printing or possibility of fusing due to setting the film upside-down, by providing an optical detection marker consisting of a releasable adhesive sheet. CONSTITUTION:One side of a detection marker sheet 2 is partially or entirely coated with a pressure-sensitive adhesive 1. For easy releasing of a detection marker, it is desirable to provide the detection marker with a dry edge. The dry edge means an edge part of the detection marker which part is not coated with the adhesive so that it can be easily held with fingers. The shape and the number of dry edge parts may be arbitrarily selected, unless the holdability of the detection marker onto the OHP film 3 is impaired. The detection marker consisting of the releasable adhesive sheet is adhered to the OHP film 3. Accordingly, the position of the detection marker can be accurately read.

摘要： PURPOSE:To obtain an OHP film free of possibility of positional errors or possibility of troubles of fusing or the like due to setting the film face side back, by providing a detection marker for optical position detection at least one part of a border part at which transfer does not take place. CONSTITUTION:A detection marker 1 is provided at least one part of a border part 2 to which a sublimable dye is not transferred at the time of printing an image. If the marder 1 is provided at a printing part 3 to which the sublimable dye is transferred, a shadow is undesirably generated when using an OHP film on an overhead projector after printing. The detection marker 1 may be provided by applying a dispersion or solution of an inorganic pigment, an organic pigment, a dye or the like and a binder such as a polyester resin, a polyamide resin and an arcylic resin in an appropriate solvent to the OHP film. The OHP film provided with the detection marker 1 ensures that the position of the marker can be accurately read by, for example, an optical reader of the transmisson type, reflection type or other type.

摘要： PURPOSE:To provide a sublimation type thermal recording image receiving medium showing no fusion even in a high density region and having sufficient sensitivity, by containing specific surface modifier in the dyeable layer of the image receptive medium. CONSTITUTION:This surface modifier is mixed with an acrylic polymer or a liquid for a dyeable layer containing said polymer as one component in a small amount and applied to the surface of an image receptive medium to be dried or cured but, during this process, it shows properties such that a graft or block chain is arranged to a coating surface and an acrylic polymer chain being a matrix is arranged in the dyeable layer and low energy responsive group such as fluorine or silicone appears on the coating surface. Therefore, the image receptive medium showing no fusion even in a high density region and having sufficient sensitivity can be obtained. A coating thickness is about 0.5-15mum, pref., 2-5mum and the modifier is uniformly applied by a roll coater such as a gravure coater or a reverse coater to be dried or cured.

摘要： PURPOSE:To enable smooth printing and ensure that a dyed resin layer is protected by a surface layer after printing, by providing a resin layer to be dyed on a raw printing paper and providing a low energy surface layer thereon. CONSTITUTION:A resin liquid comprising 20 parts of a saturated linear polyester resin and 80 parts of methyl ethyl ketone is applied to a wood free paper, followed by drying to provide the resin layer to be dye, and a surface protective resin liquid comprising 2 parts of a silicone resin, 0.1 part of activated platinum catalyst and 97.9 parts of hexane is applied to the resin layer, followed by hardening by heating to obtain a thermal transfer recording paper having a three-layer construction composed of the raw paper, the resin layer to be dyed and the low energy surface layer. A thermal transfer ribbon and the thermal transfer recording paper are laminated, and the laminate is heated from the back side of the ribbon by a thermal head to print. Accordingly, not any fusion occurs between the ribbon and the paper, both of them can be clearly released from each other, and images with favorable color density can be obtained.
