PURPOSE:To form a recording image having high density and various excellent fastnesses even when heat energy is applied for a short time, by containing a specific dye in the dye support layer formed to one surface of a base sheet. CONSTITUTION:A dye represented by formula [I] [wherein X is a phenyl group which may have a substituent or an E7-C(CH3)2-group (wherein R7 is an alkyl group, an alkoxy group, an aryloxy group or a thioalkyl group), Y is a group represented by formula [II] (wherein R1-R4 are a hydrogen atom, a hologen atom, an alkyl group, a cycloalkyl group, an alkoxy group, an acylamino group, an aminocarbonyl group, an alkylaryl group, a cyano group or an aryl group) and R5 and R6 are a hydrogen atom, an alkyl group, an aralkyl group or an aryl group] is contained in the dye support layer formed on one surface of a base sheet. The dye represented by the formula [I] is obtained by the coupling of a p-phenylenediamine compound and acylacetoanilide. |
