PURPOSE:To obtain an image-receiving base for a printer which is excellent in strength, heat resistance and printability and is free of curling, by providing an anti-sticking layer on at least one side of a biaxially stretched film comprising a specified polyester copolymer and having a cushion factor in a specified range and a yield point. CONSTITUTION:An image-receiving base for a printer comprises an anti-sticking layer on at least one side of a biaxially stretched film which comprises a polyester compolymer containing 5-30wt.% of white inorganic particles and having a crystalline heat of fusion of not more than 6cal/g and which has a cushion factor of 5-30% and a yield point in a stress-strain curve. The polyester copolymer has the predetermined crystalline heat of fusion, and is preferably a copolymeric polyester comprising an ethylene terephthalate unit as a main repeating unit. If the crystalline heat of fusion is more than 6.0cal/g, satisfactory recording by use of a sublimable dye cannot be achieved, images formed are light in color and unclear, and a fold mark is left once the image-receiving base is folded. If the cushion factor is less than 5%, the film is hard, and printability is poor. If the cushion factor is more than 30%, the film is liable to be broken. |
