PURPOSE:To minimize thermal migration and color dissolution during ink adjustment and prevent the occurrence of coagulation, dialysis, crystallization and bleedout, and reduce the possibilities of retransfer and blurring of an image in the process of aging by adding a specific thermally migratable color to a color-donative layer containing a thermally migratable color on a support. CONSTITUTION:A color-donative layer of a thermally migratable color-donative material with a color-donative layer containing a thermally migratable color on a support, contains a thermally migratable color expressed by formula (I). In the formula (I), R<1> and R<2> are a hydrogen atom, an alkyl group, an aryl group, or a heterocyclic group; R<3>, R<4>, R<5>, R<6> and R<7> are a hydrogen atom or a non-metal substitution group; Za, Zb and Zc are -N-, or -C(R8)=; and R<8> is a hydrogen atom or a non-metal substitution group. At least, either one of R<7> or R<8> is an aryl group or a heterocyclic group with a substitution group at the ortho position of a bonded position, R<3> and R<4> and/or R<4> and R<1> and/or R<1> and R<2> and/or R<2> and R<5> and/or R<5> and R<6> may form a ring structure through mutual bonding. |
