Abstract

1294355 Photographic material & process EASTMAN KODAK CO 23 July 1970 [25 July 1969] 37406/69 Addition to 1072862 Heading G2C [Also in Division B2] A photo-resist image is prepared by (1) exposing a silver halide emulsion layer, (2) developing with a 1,4-dihydroxybenzene tanning developing agent, (3) contacting (before or during development) with a material comprising in order (a) a support, (b) a clear, substantially unhardened, hydrophilic colloid (especially gelatine) layer, and (c) a non-photosensitive, substantially unhardened, pigmented colloid layer, so that oxidized developer hardens the colloid layers imagewise, and (4) removing the substantially unhardened areas of the colloid layer. A photographic material for use in the process may comprise the silver halide emulsion layer coated on layer (c) overlying (b) and (a). Apart from the use of layer (b), the process is the same as that of Parent Specification.
