TRANSFER BODY FOR SUBLIMATION TYPE HEAT-TRANSFER RECORDING, AND IMAGE RECEIVING BODY FOR SUBLIMATION TYPE HEAT-TRANSFER RECORDING

摘要

PROBLEM TO BE SOLVED: To improve the preservation characteristics under a high temperature, high humidity condition by a method wherein for a transfer body having a color material layer which contains a polysiloxane-polyoxyalkylene block copolymer on one surface of a material, as the copolymexr, one having a constituent unit which is represented by a specified formula is used. ;SOLUTION: For this transfer body which is used for a sublimation type heat-transfer recording using a recording means such as a thermal head or an optical head of a laser, on one surface of a base material, a color material layer containing a dye, a binder and a polysiloxane-polyoxyalkylene block copolymer, is formed. In this case, for the polysiloxane-polyoxyalkylene block copolymer, one having a constituent unit represented by the formula is used. In the formula, (a), (b) are an integer which is 2 or higher, R1 is hydrogen atom or a univalent hydrocarbon group, R2 is a univalent hydrocarbon group, and (n) is an integer of 2-4. For a (C_nH_zn-O)_b unit, one which has two or more (C_nH_zn-O)_b units wherein the (n) value is different, may be used.;COPYRIGHT: (C)1999,JPO
