ABSTRACT:
A biaxially orientated polyester film for sublimitation type thermal transfer printing having a coating layer and a sublimation type ink layer formed on the coating layer. The coating layer comprises an aqueous acrylic resin (A), an aqueous polyester (B) and an aqueous epoxy compound (C), weights of which satisfy the relationships: (1) 0.30.ltoreq.W.sub.A .ltoreq.0.90, (2) 0.10.ltoreq.W.sub.B .ltoreq.0.50, (3) 0.05.ltoreq.W.sub.C .ltoreq.0.30, and (4) 0.25.ltoreq.W.sub.C /W.sub.B .ltoreq.2 in which W.sub.A, W.sub.B and W.sub.C are weight ratios of the aqueous acrylic resin (A), the aqueous polyester (B), and the aqueous epoxy compound (C), respectively based the whole weight of the coating layer.
