Abstract: PROBLEM TO BE SOLVED: To obtain an aqueous heat-sensitive pressure-sensitive adhesive composition which can be thermally dried at a higher temperature after applied, does not cause blocking even when stored for a long time, and can be made sticky at an activation temperature equivalent to that of prior art. SOLUTION: This pressure-sensitive adhesive composition contains a solid plasticizer, a thermoplastic resin, and a tackifier. The plasticizer has a melting point of 70 deg.C or higher. The tackifier has a softening point of 150-180 deg.C. An example of the plasticizer is bis(cis-3,3,5-trimethylcyclohexyl) phthalate, and the content of it is about 350-800 pts.wt. based on 100 pts.wt. thermoplastic resin. A heat-sensitive pressure-sensitive adhesive sheet can be produced by applying the composition to at least one side of a carrier to form a pressure- sensitive adhesive layer.

Abstract: PROBLEM TO BE SOLVED: To form a high-color-density clear recording image by using the dye reception layer of an image receptor for thermal transfer recording. SOLUTION: The dye reception layer is formed by using an aqueous emulsion consisting of an emulsion containing polymer particles having a crosslinkage or crosslinkable polymer particles. The polymer particles are made of a copolymer of a polyfunctional monomer having at least two polymerizable unsaturations in the molecule with a monofunctional vinyl monomer, a copolymer of a crosslinking monomer with a monofunctional vinyl monomer or a copolymer of a polyfunctional monomer having at least two polymerizable unsaturations in the molecule with a crosslinking monomer and a monofunctional vinyl monomer. The polymer particles can be made from a monomer mixture containing a (meth)acrylic monomer and an aromatic vinyl monomer (e.g. styrene).

Abstract: PROBLEM TO BE SOLVED: To form clear recording image having high color density and free from bleeding by means of a dye-receiving layer of image reception body for thermal transfer printing. SOLUTION: A dye-receiving layer is formed with a resin composition [a resin composition composed of a urethane resin (1) and a vinyl polymer (2) as resin components] containing a plasticizer which is solid at normal temperature. The examples of the plasticizer which is solid at normal temperature include dicyclohexyl phthalate, and the content of the solid plasticizer in the resin composition is about 0.1-50 pts.wt. based on 100 pts.wt. of the resin component. The resin component of the resin composition may comprise a urethane resin (1) and a polymer (2) dispersed in the urethane resin in particle state, or may be a core-shell structure comprising a urethane resin (1) and a vinyl polymer (2) or a polymeric aqueous emulsion containing polymer particles having a micro domain structure.

Abstract: PROBLEM TO BE SOLVED: To improve releasability from a thermal transfer sheet, color developing density and clarity of an image by a dye receptive layer of a thermal transfer recording image receiving element. SOLUTION: A dye receptive layer is formed of resin composition containing water soluble silicate and vinyl resin. The vinyl resin can be used in the form of water solution or aqueous emulsion. The vinyl resin contains vinyl resin (e.g. acrylic resin, or styrene resin) having a functional group selected from a hydroxyl group, carboxyl group, silyl group, amide bond, and ester bond. A ratio of the water soluble silicate to the vinyl resin is the former/the latter = 1/99 to 99/1 (by weight) in terms of solid content.

In formula I, R1 is C(CH3 )2 CH2 or an org. group; and M1 is H, Na, or K. In formula II, M2 is H, Na, or K. In formula III, R2 and R3 are each H or CH2 CH2 OH. The case when R1 is C(CH3 )2 CH2 : M1 and M2 are both Na; and R2 and R3 are both H is esp. pref. The viscosity of a 1-wt.% aq. soln. of the polymer is pref. 50-550cps. This polymer is adsorbed on the surface of clay, etc., to form a strong adsorption film and thus imparts a three-dimensional stability to clay particles and prevents them fromM contacting water.
