A photothermographic material including, 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, and a non-photosensitive layer, wherein the
photothermographic material contains a metal phthalocyanine dye
represented by formula (I): ##STR00001## wherein, M represents a metal
atom; R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7, and
R.sub.8 each independently represent a hydrogen atom or a substituent,
with at least one of them being a substituent; X.sub.1, X.sub.2, X.sub.3,
and X.sub.4 each independently represent a hydrogen atom or a
substituent; and at least one of R.sub.1, R.sub.2, R.sub.3, R.sub.4,
R.sub.5, R.sub.6, R.sub.7, R.sub.8, X.sub.1, X.sub.2, X.sub.3, and
X.sub.4 is an oil-soluble group. The invention provides a
photothermographic material which exhibits preferable image tone and
excellent image storability.
