THERMAL TRANSFER RECORDING RESIN COMPOSITION AND IMAGE RECEIVING ELEMENT

摘要

PROBLEM TO BE SOLVED: To form a clear recording image with excellent releasability from a thermal transfer sheet and high color developing density by a dye receptive layer of a thermal transfer recording image receiving element. SOLUTION: A dye receptive layer is formed of resin composition constituted by a core-shell structure in which glass transition temperature Tg1 of the one polymer of polymers for forming a core and shell is lower than 30 deg.C (e.g. -50 to 25 deg.C), that Tg2 of the other polymer is 30 deg.C or higher (e.g. 30 to 110 deg.C), and glass transition temperature difference Tg=Tg2-Tg1 of the both is 10C or higher (e.g. 20 to 150 deg.C). The one polymer of the polymers for forming the core and shell is formed of aromatic component and may be formed of resin composition in which concentration of the component is 5 to 80 wt.% of the overall core and shell polymer.
