PURPOSE:To satisfy thermal diffusibility, a hue, heat resistance and lightfastness and to enhance fixabilities to a large extent hy providing a thermal layer containing a specific dye compound on a support. CONSTITUTION:A thermal layer containing at least a dye compound represented by formula is provided on a support. In the formula, R<1> and R<2> are respectively an alkyl group, an aryl group or a heterocyclic ring residue, R<3> is a hydrogen atom, a halogen atom, an alkyl group, an aryl group, an alkoxy group, a cyano group, an acylamino group, an alkylthio group, a sulfonylamino group, an ureido group, an alkoxycarbonyl group, a sulfonyl group, an acyl group or an amino group, n is an integer of 1-4 and R<3> may be same or different when n is 2-4. |
