DYE TRANSFER IMAGE RECEPTIVE SHEET

摘要

PURPOSE:To enhance sensitivity and developed color density with respect to a transferred dye image, to form a sharp image and to impart excellent preservability by containing a novel polyester resin in an image receptive layer. CONSTITUTION:An image receptive layer is based on a resin wherein a polycondensation product of a diol component and a dicarboxylic acid component and a polyester type polymer having a glass transition point of 65 deg.C or higher and a number average MW of 22000 or less are crosslinked. The used polyester type polymer has a number average MW of 200000 or less and this number average MW is pref. 8000-18000. The diol component contains an ethylene oxide adduct of ethylene glycol and bisphenol A. The dicarboxylic acid component is selected from aromatic dicarboxylic acids such as terephthalic acid or the like. The polyester type polymer forms a crosslinked resin and a crosslinking agent has 1mol equivalent or more of a crosslinkable functional group per 1mol. of polyester.
