Abstract
1441223 Thermally-developable photographic material FUJI PHOTO FILM CO Ltd 17 July 1974 [17 July 1973 25 Feb 1974] 31762/74 Heading G2C A thermally-developable photographic material comprises a support bearing at least one layer or layers which together comprise: (a) a silver salt of an aliphatic acid, (b) a light-sensitive silver halide, or a compound capable of forming a light-sensitive silver halide by reaction with the silver salt (a), in an amount effective to catalyze the reaction of components (a) and (c), (c) a reducing agent capable of reducing to elemental silver the organic silver salt (a) when the latter is in the presence of the component (b) which has been exposed to light and is being heated, the reducing agent having the general formula wherein R<SP>1</SP> and R<SP>2</SP> each represents an alkyl group or R<SP>1</SP> and R<SP>2</SP> can combine to form a ring; R<SP>3</SP>, R<SP>4</SP>, R<SP>5</SP> and R<SP>6</SP> each represents hydrogen or an alkyl, cycloalkyl or aryl radical, not all being hydrogen; or by the general formula wherein R<SP>7</SP>, R<SP>8</SP>, R<SP>9</SP> and R<SP>10</SP> each represent a hydrogen atom, an alkyl, a substituted alkyl, cycloalkyl, aryl or substituted aryl group, not all being hydrogen; and R<SP>11</SP> represents an alkyl, substituted alkyl, allyl, aryl or substituted aryl group; and (d) a binder. The substituted aryl may be phenyl having 1 or 2 substituents selected from halogen, hydroxyl, nitro, aralkyl, alkoxy, carboxylic, carbomethoxy, acetyloxy or aryl. Compound (b) may be hydrogen halide, ammonium halide, metal halide, triphenylmethyl chloride or bromide, 2- bromo-2-methylpropane, 2-bromobutyric acid, 2-bromoethanol, dichlorobenzophenone, iodoform, chloroform, CCl 4 or an N-halo-compound containing the group -CO-N<SP>1</SP>-X where X is halogen. The layers may also contain a sensitizing dye.
