摘要： PROBLEM TO BE SOLVED: To provide a method of using a scratching thermal transfer sheet, which has enough hiding properties not easily discriminating information recorded on a card or the like as it is and in which a hidden part can be easily rubbed off with a finger nail or a coin, and a body to be transferred and the thermal transfer sheet used therefor. SOLUTION: A protective layer is transferred on the information recorded on the body to be transferred such as a card, a ticket or the like by means of the thermal transfer sheet having the protective layer thereon. Next, by means of the thermal transfer sheet provided with a scratching layer, which can hide the information record of the body to be transferred and which can be removed from the body to be transferred, the scratching layer is thermally transferred so as to laminate the protective layer and the scratching layer in the order named on the information recording part of the body to be transferred. Thus, the protective layer acts as a filler by smoothing the raising of the information recording part and the unevenness of the base material of the body to be transferred or the like and, the thermal transfer sheet can realize its full hiding properties and easily rubbing-off of the hidden part.

摘要： PROBLEM TO BE SOLVED: To provide a thermal transfer sheet for scratching capable of easily rubbing off a concealing part by a pawl, a coin or the like by incorporating sufficient concealability so as not to easily identify information recorded on a card or the like as it is. SOLUTION: The thermal transfer sheet 1 comprises a non-transferable mat layer 3 provided at least on an overall surface or in a pattern state and a heat fusible ink layer 4 containing an aluminum pigment, a carbon black, a wax, an ethylene-vinyl acetate copolymer resin as main constituents and sequentially provided on one side surface of a film base material 2. Thus, a concealing layer of the layer 4 is transferred on information recorded on a card or the like so that the front surface of the transferred concealing layer is mat-like rugged which cannot read the recorded information due to protrusions. The above components are contained in the layer 4 to allow the concealing layer to be easily rubbed off by a suitable cohesive force and a pawl, a coin or the like.

摘要： PROBLEM TO BE SOLVED: To provide a recording sheet for easily forming a receptive layer in a short time having excellent fastness such as excellent ink absorbency, drying characteristics, water resistance and the like without stimulating or getting a rash at a skin when brought into contact without retaining a monomer after an ionizing radiation is emitted. SOLUTION: A recording sheet 1 is formed by coating at least one surface of a base material sheet 2 with an ionizing radiation curable hydrophilic multifunctional monomer and/or a composition containing an oligomer as a receptive layer 3, emitting it with an ionizing radiation to cure the layer 3. In this case, since a monofunctional monomer and/or the oligomer is not used for the layer 3, no monomer exists after the radiation is emitted, and when brought into contact, a skin is not stimulated or does not get a rash. The multifunctional monomer and/or the oligomer can suitably incorporate functions of absorbency, drying characteristics of aqueous ink, and water resistance of an obtained printed matter with good balance by suitably selecting number of functional groups and adding amounts.

摘要： PROBLEM TO BE SOLVED: To provide a laser heat transfer recording material which prevents the break of a light/heat conversion layer itself by laser beam from occurring and also prevents the printing sensitivity from being deteriorated and further shows the high clarity of a recorded image and rapid image recording. SOLUTION: The laser heat transfer recording material has at least a light/ heat conversion layer composed mainly of a near infrared ray absorbing material and a binder resin and a heat transfer ink layer laminated in that order, on a base. The binder resin to be used is a crosslinked resin composition and therefore the high sensitivity heat transfer recording material is obtained which shows high heat resistance in the light/heat conversion layer and is not softened even at the time of high laser beam output. In addition, appropriate foil retaining properties and high heat resistance are obtained by using carbon black which is an inorganic particle material as the near infrared ray absorbing material.

摘要： PROBLEM TO BE SOLVED: To provide a laser thermal transfer recording material for rapidly recording by preventing a damage of a photothermal conversion layer itself by a laser beam, and preventing a decrease in a printing sensitivity with excellent clarity of a recorded image. SOLUTION: The laser thermal transfer recording material is obtained by sequentially laminating a photothermal conversion layer containing at least a near infrared absorbing material and a binder resin as main bodies and a thermal transfer ink layer in this order on a base material in such a manner that the resin having a glass transition temperature of 100 deg.C or higher is used. Thus, the thermal transfer recording material having a high heat resistance of the conversion layer, no softening even at the time of outputting a high output laser beam and high sensitivity is obtained. Further, when a carbon black of an inorganic particle material is used as the absorbing material, a suitable foil durability and high heat resistance can be performed.

摘要： PROBLEM TO BE SOLVED: To realize the formation of a high density and high contrast full color image or the like by a method wherein a water base ink receiving layer is equipped and, at the same time, a white porous layer, which turns to be transparent by absorbing water, is provided on one side of a transparent base material. SOLUTION: By applying a solution prepared by adding 30 pts.wt. of a xylene to 100 pts.wt. of a standard solution A on the surface of a base material 3 made of a transparent polyethylene telephthalate film having the thickness of 100 μm, by a bar-coating method so as to form a solid content under dry state of 10 g/m in order to form a white porous layer 1. In this case, the standard solution A is a polyvinyl butyral solution dispersed with fine polyacrylic acid particles, which is obtained by dissolving 3 g of polyvinyl butyral having the degree of polymerization of about 300 in 120 g of methyl ethyl ketone, which is a good solvent, so as to obtain a hydrophobic matrix polymer and by performing a radical polymerization reaction at 60 deg.C for 8 hours in nitrogen gas flow after 20 g of acrylic acid and 0.5 g of α,α-azobisisobutyronitrile as a polymerization initiator are added to this hydrophobic matrix polymer solution.

摘要： PROBLEM TO BE SOLVED: To obtain printing compatibility under not only the atmosphere of normal temperature and normal humidity but also the atmosphere of high temperature and high humidity or low temperature and low humidity by a method wherein an ink receptive layer is constituted of the principal constituent of the mixture of aqueous water-insoluble resin, in a recording sheet provided with the ink receptive layer on at least one side thereof. SOLUTION: A substrate sheet 2, employed in a recording sheet 1, can be constituted of a normal substrate sheet as it is and there is no limit especially. An ink receptive layer 3, formed on one side of the substrate sheet 2, is constituted principally of the mixture of aqueous water-insoluble resin and a water-soluble resin having a resistance to moisture and heat as well as low-temperature printing property while the mixture is preferable to be the combination of aqueous polyester resin, polyvinyl alcohol and polyvinyl pyrrolidone. The water-soluble resin, having a resistance to moisture and heat as well as low-temperature printing property, is a resin soluble in water, alcohol or the mixed solvent of these substances while the keeping quality in respective atmospheres (temperature range: -20-50 deg.C, humidity range: 10-90%RH) is excellent and the deterioration of water absorbing property as well as printing property is little.
