Abstract

1,64,095. Physically developable light sensitive materials. EASTMAN KODAK CO. March 19, 1964 [March 19, 1963], No.11611/64. Heading G2C. A photographic material comprises a layer containing nuclei which are capable of acting as centres for physical development and, in the same layer or in an adjacent layer (1) a polysulphide which on exposure to actinic radiation forms a substance which destroys or reduces said capability e. g. bis (p-tolyl) trisulphide or (2) an organic azide which on exposure to actinic radiation releases N2 with the formation of a free radical e.g. 4-azido-3-methyl-N, N-diethyl aniline, and a compound which reacts with said free radical thereby to form or to release a physical development inhibiting substance which destroys or reduces said capability. The compounds reacted with the organic azido to form or release the development inhibiting substance are the development inhibitor releasing couplers (DIR couplers) of Specifications 932, 272 and 953, 454, e. g. 1-hydroxy-4-(2'-amino-4'-methyl phenylazoxy)-N-(#-(2", 4"-di-t-amylphenoxy) butyl)-2-naphthamide used in Example 1. The nuclei used may have a diameter of 7 - 2500Š and are such materials as Carey Lea Silver, metal e.g. Zn, Cd or Ni selenides and sulphides and silver proteinate. The DIR coupler may be incorporated in the binder of the layer containing nuclei by means of a water immiscible solvent B.P. #. 175‹C. e.g. tricresyl phosphate. The exposed material may be developed by (1) contacting with an unexposed silver halide emulsion in the presence of a silver halide solvent and a silver halide developing agent (2) swabbing with an aqueous silver salt e. g. AgNO3 solution and then immersion in a silver halide developer and (3) employing a light-sensitive material containing a complex silver salt e. g. a silver thiosulphate or 4, 5-dihydroxy hexahydro-1, 7-dioxa- 7a-hydroxymethyl-3-azoindene-2-thione complex and developing with a reducing agent e. g. silver halide developer. These physical development processes are based on silver deposition but physical development processes based on deposition of Cu, As, Sb, Pt, Au and Hg may be used.
