PURPOSE:To obtain a beautiful developed image without causing sticking of a photosensitive, pressure sensitive capsule sheet to a color developer sheet by melting during pressure development in a high humidity by incorporating a hygroscopic agent into the photosensitive, pressure sensitive capsule sheet or the color developer sheet. CONSTITUTION:A latent image is formed by exposure on a photo-sensitive, pressure sensitive capsule sheet, and the sheet 1 is pressure-developed by superposing a color developer sheet 6 on the surface having the latent image formed thereon. Thus, unexposed microcapsules 3 carried by the capsule sheet 1 are broken and reacting agent-contg. liquid is flowed out of the microcapsules 3. The reacting agent develops color by reacting with a partner of the reacting agent coated on the color developer sheet 6. In this stage, the liquid which is not absorbed completely, even in a highly humid state, by the partner and a binder 4, is absorbed by hygroscopic materials 5a, 5b contain in the binder 4 which is carried by the capsule sheet 1 or the color developer sheet 3. By this constitution, a satisfactory developed image is obtd. without causing sticking of the capsule sheet 1 to the color developer sheet 3. |
