Patent ID: 7504200

Claim:
A photothermographic material comprising on one side of a support a light-sensitive layer comprising a light-sensitive silver halide, light-insensitive silver salts of aliphatic carboxylic acids, a reducing agent and a binder resin and a first light-insensitive layer and on the other side of the support a second light-insensitive layer, wherein at least one of the first light-insensitive layer and the second light-insensitive layer comprises a silicon-containing polymer lubricant and a fluorine-containing compound represented by formula (SF) and the silion-containing polymer lubricant is a silion-containing acrylic polymer: [Rf-(L 1 ) m1 -] p -(L 2 ) n1 -(A) q Formula (SF) wherein Rf is a substituent having 2 to 16 carbon atoms and 13 or less fluorine atoms; L 1 is a linkage group having no fluorine atom; L 2 is a (p+q)-valent linkage group having no fluorine atom; A is an anion or its salt; m1 and n1 are each an integer of 0 or 1; p and q are each an integer of 1 to 3, provided that when q is 1, m1 and n1 are not 0 at the same time.
