PURPOSE:To perform formation of a recording image which has excellent transfer property, visibility, fastness, especially, heat resistant migration and light- resistance by a method wherein a dye contained in a dye carrier layer formed on one surface of a base material sheet forms a dye represented by a specified general formula. CONSTITUTION:A dye is represented by a general formula described at the right. In the formula, K represents an NHCONHCO group, an NHCONHSO2 group, an NHCSNHCO group, an NHCSNHCS group, and an NHCSNHSO2 group. R represents an alkyl group, an aryl group, a cycloalkyl group, an aralkyl group, and a heterocyclic group. R1 and R2 represent an alkyl group, a cyloalkyl group an aralkyl group, and aryl group. R<3> represents a hydrogen atom, a halogen atom, a cyanogen group, an alkyl group, a cycloalkyl group, an alkoxy group, an aralkyl group, and an aryl group. Further, R<4> and R<5> may be the same or different and each represents a hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, and an acylamino group. X represents a hydrogen atom. |
