PURPOSE:To improve light resistance and deterioration for regenerative characteristics, by providing a recording layer constituted of a monomolecular built-up film comprising a polymethine coloring matter and a monomolecular built-up film comprising a metal complex having absorbance in a wavelength region on the longer wavelength side of that of the coloring matter on a base. CONSTITUTION:The recording layer which consists of a laminated structure of a monomolecular built-up film comprising a polymethyine coloring matter and a monomolecular built-up film comprising a metal complex having absorption in a wavelength region on the longer wavelength side of that of the coloring matter or consists of a mixed built-up film comprising both the coloring matter and the complex is provided on the base, either directly or through an undercoat layer. The polymethine coloring matter may be merocyanine, cyanine or the like, and the metal complex may be an anthraquinone coloring matter, a phthalocyanine coloring matter or the like. |
