Abstract
1510539 Heat development materials EASTMAN KODAK CO 16 July 1975 [16 July 1974] 29848/75 Heading G2C Heat-developable material having a layer or layers comprising (a) a silver halide, (b) a silver salt of a heterocyclic thione of the Formula:- wherein R represents atoms which complete an unsubstituted or substituted heterocyclic nucleus having a five membered ring and Z is a C 1-30 alkylene group, (c) an organic reducing agent and (d) a polymeric binder has adjacent the heatdevelopable layer(s) a polymeric layer containing at least 50% of an acrylamide polymer which is either polyacrylamide or a copolymer formed of at least 60% of acrylamide units, the remaining units being of the Formula #CH 2 CR<SP>1</SP>R<SP>2</SP># wherein R<SP>1</SP> is hydrogen or a C 1 - 4 alkyl group, and R<SP>2</SP> is a hydroxyl or hydroxyl-containing group, an N- substituted carbamoyl group, an active methylenecontaining group, an unsubstituted or substituted imidazolyl, 2-pyrrolidonyl or pyridyl group, or an unsubstituted or substituted heterocyclic ammonium salt group having a 5- or 6-membered ring containing the azonia nitrogen atom. The acrylamide polymer may have a M.W. of 100,000- 2,000,000. The acrylamide layer may be above or below the heat-developable layer(s), which may also comprise said acrylamide polymer. A portion of the reducing agent may be in the acrylamide layer.
