Zusammenfassung:	PURPOSE:To obtain stable humidity resistance over a range of low to high humidities by adding at least, a single type of resin selected from a group of rosin, rosin ester and alicyclic saturated hydrocarbon resin to an image receiving layer to be transferred to the surface of a permanent support. CONSTITUTION:The recommended organic polymer material used as the first layer is such as one containing at least, one type selected from among a copolymer of polyvinyl chloride, vinyl chloride and vinyl acetate, a copolymer of vinyl chloride, vinyl acetate and vinyl alcohol and a copolymer of vinyl chloride, vinyl acetate and maleic acid, each having a softening point of 150 deg.C or lower and a molecular weight of 200 to 2000, although a variety of materials can be used. An image receiving sheet material is peeled off when the second image receiving layer is retransferred to a permanent polymer material. An organic polymer material used as the second layer is a thermally adhesive material which is not susceptible of a change in physical properties due to humidity absorption. In addition, it is recommended that at least, one type selected from among low hydrophilic rosin, rosin ester and alicyclic saturated hydrocarbon resin which are soluble in an alcoholic solvent be added.
