Description

ABSTRACT:
A photothermographic material having, on at least one side of a support, an image forming layer including at least a photosensitive silver halide, a non-photosensitive organic silver salt, a reducing agent, and a binder, wherein 1) the binder includes a polymer latex having a monomer component represented by formula (M):in-line-formulae description="In-line Formulae" end="lead"?CH2═CR01—CR02═CH2  Formula (M)in-line-formulae description="In-line Formulae" end="tail"?2) the photothermographic material includes a compound represented by formula (SA):and 3) the photothermographic material further includes a metal phthalocyanine dye represented by formula (PC-1):wherein at least one of R1, R4, R5, R8, R9, R12, R13, and R16is an electron-attracting group. The invention provides a photothermographic material which produces an image free from unevenness in color tone, having high image quality, and is excellent in image storability.
