PURPOSE:To obtain a heat transfer sheet capable of forming clear images, bleed resistance, stain resistance and high concentration comprising a substrate sheet and a dye carrying layer containing a specific dye mixture formed on the substrate sheet. CONSTITUTION:A substrate sheet comprising polyester sheet, paper, etc., is prepared and a dye carrying layer containing mixed dye of dye shown by the formula (R1 to R4 are 1-6C alkyl, cycloalkyl, etc.; R2 is H or alkoxy; R3 and R4 may form ring) and subliming dye shown by the formula Il, having 560-700nm maximum absorption wavelength and >=345 molecular weight is formed on the surface of the substrate sheet to give a heat transfer sheet to produce images having excellent coloring concentration and fastness. |
