摘要： PROBLEM TO BE SOLVED: To decompose and remove harmful materials such as malodorous materials and bacteria, to neutralize and remove various aldehydes and acids formed by the decomposition of the harmful materials and to prevent the deactivation of an adsorbent by the acids by preparing a deodorant from at least a photoreactive semiconductor and an amine-contg. sheet phosphate. SOLUTION: The deodorant that can adsorb and remove aldehydes, etc., formed by the decomposition of harmful materials by the photocatalytic action of a photoreactive semiconductor is prepd. from the photoreactive semiconductor and an amine-contg. sheet phosphate. The deodorant is incorporated into a substrate such as a nonwoven fabric or applied to a substrate to form the objective deodorization sheet. The photoreactive semiconductor is preferably a semiconductor having 1-3 eV forbidden band width and causing a photocatalytic reaction and particles of the semiconductor having 10-500 m /g specific surface area are appropriately used. The amine in the amine-contg. sheet phosphate is, e.g. vinylbenzyldimethylamine as a compd. having a tert. amino group.

摘要： PROBLEM TO BE SOLVED: To make it possible to repeel/rejoin a material to be applied even after applying the material once without adversely affecting ink jet-recorded data during an application process by forming an ink receptive layer on one of the faces of a support and a pressure-sensitive adhesive layer which can be applied in a freely peelable manner on the other face. SOLUTION: At least, one or more ink receiving layers are formed on one of the faces of a support and a pressure-sensitive adhesive layer which can be applied in a freely peelable manner is formed on the other face. A barrier layer can be formed between the repeelable pressure-sensitive adhesive and the support. In addition, the barrier layer can be formed adjacent to the support and the ink receiving layer can be formed on the barrier layer. In this recording sheet, the pressure-sensitive adhesive layer requires a large release power when peeling it as the repeelable pressure-sensitive adhesive layer is present on the opposite face to the ink receiving layer, so that the ink receiving layer can be peeled without damaging it. Thus this recording sheet is easily peeled and applied and besides, has outstanding position control and peeling properties.

摘要： PROBLEM TO BE SOLVED: To provide an anti-counterfeiting sheet/anti-counterfeiting adhesive- backed tape with which it is difficult to permit an illegal conduct to tray to peel off a label or remove a seal from a stamp or a ticket with an organic solvent, and easy to judge whether it is true or false. SOLUTION: A layer 2 containing a colourless or light coloured basic dye as a colour developing agent and an organic or inorganic acid substance as a developer or a self-colour-developing type pressure sensitive colour developing layer is provided on one side of a substrate 4, and a printing layer is overlaid thereon which uses an ink composition containing a dye in which an organic solvent is dissolved, whereby an anti-counterfeiting sheet is provided. In the even that an organic solvent is applied, when an organic solvent dissolved dye flows out of a printing portion or the colour developing portion is developed, its trance can clearly be confirmed, this preventing illegal conducts such as illegal re-application of a label 8 or illegal removal of a seal. In addition, when the colour developing layer is unnaturally developed, it can easily be judged whether the sheet is true or false.

摘要： PROBLEM TO BE SOLVED: To laminate an adhered body such as postcards and recording paper efficiently by superimposing one or more sheets of foamed polyolefin sheets on a set or more of superimposed adhered body and heat adhesion type record ing paper, and heating them through electromagnetic waves, and adhering the recording paper and adhered body through a thermal expansion of the sheet. SOLUTION: Polyolefin sheets 1, 1 are laminated on both the side of a superimposed postcard laminate 2 of an adhered body (a postcard) and heating adhesion type recording paper. In the next place, this is fastened by rubber rings and the like to subsequently be heated through electromagnetic waves, thereby forming an adhesion recording paper by heating while pressurizing the recording paper and postcard through a thermal expansion of the foamed polyolefin sheet 1. Furthermore, the postcard laminate 2 comprising the postcard and heat adhesion type recording paper and foamed polyolefin sheet 1 are superimposed on an adhesion binder, and its entire part is secured by a bottom plate 5 and ceiling plate 3, so that the postcard and recording paper sustain no dislocation during heating, and thereby an adhesion recording paper can also be formed by conducting a heating and adhering operation.

摘要： PROBLEM TO BE SOLVED: To record a recording sheet wherein a self-color developable pressure-sensitive recording can be obtained and the developed calor part is erased with the elapse of time and a developed color mark is eliminated by setting a self-color developable pressure-sensitive layer on a desensitizer capsule-containing color developing and erasing self color developable pressure-sensitive layer. SOLUTION: At least one of color former or coupler is microencapsulated 3 or 5 and respectively independently laminated or mixed to be applied to the single surface 1 to obtain a color developing or erasing self-color pressure-sensitive recording sheet 6 having a self-developable pressure-sensitive layer. At this time, the self-color developable pressure recording layer is the desensitizer capsule 4-containing colors 4 developing and erasing type self-developable pressure-sensitive layer. By this constitution, ink jet recording, thermal recording, printing and magnetic recording become possible and, performing printing pressure, the self-developing pressure sensitive recording layer can develop a color and, since the color development is reduced as the elapse of time, this method can be used in forgery prevention and the mark of a genuine check is not left.

摘要： PURPOSE: To provide a pressure sticking adhesive and re-releasable recording sheet, and a pressure-sticking recording sheet. CONSTITUTION: An adhesive recording sheet 6 is composed of a self-coloring heat- sensitive recording layer 2 formed by using a coloring agent and a developer, at least one of which is capsulated and laminating them or mixing them together to form a simple layer, a polyolefin resin layer 4 and a pressure-sensitive adhesive layer 5 to be stuck releasably by fixing respective coated faces of the bonding agent each other without representing adhesive properties and bonding properties in the ordinary state and pressurizing, which are laminated successively on one surface of an opaque substrate 1. A double-sided adhesive recording sheet with a pressure-sensitive strong adhesive layer is formed on the uncoated layer surface side of the recording sheet, and a pressure-sticking recording sheet is formed by using the recording sheets. Print recording can be performed by pressing from above the pressure-sensitive layer of the re-releasable adhesive recording sheet by the arrangement, and the external information is sealed and integrated releasably, which can be used as a releasable postcard by laminating the pressure-sensitive adhesive layers and fixing them by pressure.

摘要： PURPOSE: To provide a lamination type pressure-sensitive recording sheet concealing recording content. CONSTITUTION: A color former and a coupler both of or one of which is microencapsulated are independently laminated to the single surface of a support 5 or mixed to be laminated thereto to provide a single pressure-sensitive recording layer 4 and a surface laminate layer composed of a thermoplastic resin is further provided thereon to form a laminated pressure-sensitive recording sheet 7 and this sheet 7 and an opaque cover sheet 6 wherein a rear laminate layer 2 composed of a thermoplastic resin is provided on the single surface of a cover base material 1 are laminated so that the surface and rear laminate layers 3, 2 are bonded in a releasable manner to produce a lamination type pressure-sensitive recording sheet 9. Therefore, by pressing the recording sheet 9 on the side of the opaque cover sheet, data can be recorded on the internal pressure-sensitive recording part and the peeled opaque cover sheet is not again bonded. This recording sheet 9 has good releasability and seeing-through preventing function.
