摘要： PURPOSE:To enable favorable images to be printed on a variety of printing materials such as a rough paper, a document and various printed matters, by providing a thermoplastic adhesive layer and a pressure-sensitive adhesive layer on the back side of a base provided with a dyeable resin layer for receiving a sublimable dye transferred thereto. CONSTITUTION:A pressure-sensitive adhesive layer 4 and a thermoplastic ahesive layer 3 are provided on the back side of a base 2. The adhesive layer 3 not provided with the adhesive layer 4 is placed on a printing material 5, and after accurate setting at a desired position, the adhesive layer 4 is supported, and thermocompression bonding is performed, whereby a strong adhesive force can be obtained. As a result, lamination can be performed extremely easily and accurately. As the base 2, one formed of a soft thin material is used. The adhesive layer 4 may be provided at any position on the back side of the base 2, but it is preferably provided at a marginal part to which a sublimable dye is not transferred. A dyeable resin layer 1 may be formed of any of various thermoplastic resin capable of being dyed with sublimable dyes, for example, a polyamide resin.

R'' is CnH2n-1, X is H or F, n is an integer of 12-22, m is an integer of 0-3 and l is an integer of 1-10. When R' is OR'', R is H] and 20-95pts.wt. of a vinyl monomer copolymerizable with said monomer is formed. As the acrylic monomer, long chain alkyl acrylate or methacrylate, long chain alkyl vinyl ether, etc. are used and, as the polymerization initiator used in the copolymerization of the copolymer, an org. peroxide or azo type initiator is used.

摘要： PURPOSE:To obtain an extremely excellent anti-blocking property, by providing a layer of a material obtained by cross-linking and hardening a specified polysiloxane having a terminal vinyl group by a peroxide in a specified thickness on the side on which heat is applied. CONSTITUTION:The layer of a material obtained by cross-linking and hardening a polysiloxane having a terminal group with eta=2-1,000,000 of formula (1), (2) or (3), wherein A is -CH=CH2, Me is methyl and Ph is phenyl, be a peroxide is provided on the side on which heat is applied. The peroxide is preferably a diacyl peroxide such as benzoyl peroxide. The thickness of the layer in the hardened state is set to be 0.02-1mum. If the thickness is less than 0.02mum, a uniform effect can not be expected, whereas if the thickness is more than 1mum, the sensitivity of the ink sheet is lowered. Accordingly, blocking can be prevented from occurring where the ink sheet is rolled or stacked.

摘要： PURPOSE:To prevent the occurrence of blocking in the case when an ink sheet is formed in a roll or a laminate, by forming a layer of specific polydimethyl siloxane. CONSTITUTION:A layer of polydimethyl siloxane expressed by a general formula (I) is formed on the side of an ink sheet whereon a quantity of heat is impressed. In the formula, (n) is 50-6,000. In order to form the layer of polydimethyl siloxane expressed by the general formula (I) on the ink sheet, the compound as it is, or the one diluted with an inactive solvent, is formed on the ink sheet. The desirable thickness of coating is 0.02-1mum, or preferably 0.05-0.5mum. Although the ink sheet whereon the layer of polydimethyl siloxane is formed is not limited particularly, an especially conspicuous effect is produced with respect to the one of a melt transfer type.

摘要： PURPOSE:The titled composition excellent in thermal, electrical and mechanical properties, by introducing an aliphatic tetracarboxylic acid into a specified polyester-polyol, reacting the terminal groups of the product with a diamine unit a predetermined amount of residual acid groups is reached and forming a salt with a nitrogen-containing basic compound. CONSTITUTION:As a polyester skeleton, there is used a substantially linear polyester-polyol having an average MW of below 1,200 and hydroxyl groups at the molecular terminals. This polyester-polyol is reacted with an aliphatic tetracarboxylic acid in an amount to provide 1.5-4.5eq. of acid groups per eq. hydroxyl groups. Then a modified polyester resin having the ratio of residual acid groups 80-25% is prepared by reacting the above-produced acid group-terminated polyester-polyacid with 0.45-0.8eq. of diamine per eq. acid groups of the polyester- polyacid. The residual acid groups of the modified polyester resin are coverted into a salt form by use of a nitrogen-containing basic compound to obtain an aqueous composition for which water can be used as a principal solvent.
