PURPOSE:To provide a thermal transfer image receiving sheet having sufficient forming strength, transfer accepting properties, transfer density properties, resistance to scratching, resistance to wear, and outdoor weather resistance by providing an image receiving layer mainly composed of a polycaprolactone having a main chain structure shown by a specific formula on a substrate. CONSTITUTION:A thermal transfer image receiving sheet is formed by providing an image receiving layer 2 mainly composed of a polycaprolactone having a main chain structure shown by formula I on a substrate 1. The polycaprolactone is a kind of polyester having a main chain structure shown by the formula I and is characterized by its outdoor weather resistance, its high forming strength, and its clear melting point of 100 deg.C or lower, which is based on its high crystallizability in spite of its high molecular weight in comparison with a conventional polyethylene terephthalate polyester. In this manner, the sheet has superior heat sensitive characteristics that it keeps the high forming strength below the melting point without tending to soften but sharply melts when reaching the melting point. |
