Abstract

377,063. Photographic sensitive materials. KODAK, Ltd., Kingsway, London.-(Assignees of Stuber, W. G.; 343, State Street, Rochester, New York, U.S.A.) Nov. 19, 1931, No. 32089. Convention date, Dec. 11, 1930. Drawings to Specification. [Class 98 (ii).] A photographic plate or film comprises a transparent support coated with a slow sensitive silver halide emulsion containing a translucent light-diffusing material such as starch and overcoated with a fast silver halide emulsion. A layer containing gelatine, which may be of an antihalation nature, may be provided on the opposite side of the support. The Specification as open to inspection under Sect. 91 (3) (a) also describes a photographic plate or film having a translucent non-sensitive light-diffusing layer coated with a fast silver halide emulsion. This subject-matter does not appear in the Specification as accepted.
