INK COMPOSITION AND TRANSFER SHEET USING THE SAME, AND INFORMATION RECORDING MEDIUM USING THE SAME

PROBLEM TO BE SOLVED: To provide an ink composition which enables to use a cellulose acetate resin as a protective layer with a usual coater, a transfer sheet and an information recording medium using the same. SOLUTION: The transfer sheet has on a substrate (2) a transfer layer (16) formed by sequentially disposing a protective layer (3) having peel property based on a cellulose acetate resin having a polymerization degree of 140-180 and an acetylation degree of 53-60, an anchor layer (4) comprising an ink composition prepared by mixing a cellulose acetate resin having a polymerization degree of 140-180 and an acetylation degree of 53-60, a polyester polyol resin and hexamethylene diisocyanate in a solid weight ratio of 30:70:20 to 70:30:20, and an adhesive layer (5). The information recording medium is obtained by sequentially stacking a hiding layer (14) and a pattern printed layer (15) on an information recording layer (13) disposed in at least part of one surface of a substrate (12) and further transferring the transfer layer (16).
