PURPOSE: To enhance developed color density of images or the like by providing a dyeable layer comprising a copolymer obtained by addition polymerization of an aromatic polyester with a lactone and having a glass transition temperature of at least 20°C on a base to produce an image-receiving material for sublimation transfer.

CONSTITUTION: A dyeable layer comprising as a main constituent a dyeable resin comprising as a main constituent a block copolymeric polyester resin which is obtained by addition polymerization of a lactone with an aromatic polyester having an aromatic dibasic acid as an acid component and which has a glass transition temperature of at least 20°C is provided on a base such as a paper, a synthetic paper, a film or the like to obtain an image-receiving material for sublimation transfer. The block copolymeric polyester can be obtained by bringing the aromatic polyester and the lactone into polyaddition reaction in a molten state or in a solution. The average molecular weight of the block copolymeric polyester is preferably 5,000-100,000.
