<P>PROBLEM TO BE SOLVED: To provide a copy sheet which is easy to handle, is neat and has quality and durability reinforced in transfer. <P>SOLUTION: The copy sheet (CB) contains a first layer (1) having an incorporated solvent, especially a microcapsulated solvent (S) and a second layer (2) containing at least one color-developer (3). By means of an extrinsic action or effect, the solvent (S) contained in the first layer (1) penetrates a position to which the extrinsic action or effect by the second layer (2) is applied. Thereby, at least one color-developer (3) in the second layer can be at least partially released by the solvent (S) in the copy sheet (CB). In a preferable state, the first layer (1) contains an additional color-developer (4), especially, a leuco dye. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
