Abstract
952,339. Colour photographic processes. KODAK Ltd. June 8,1960 [June 11,1959],No. 20160/60. Heading G2C. In reversal processing a multilayer material is given a benzothiazolium or naphthothiazolium salt treatment between black and white development and colour development to inhibit the production of colour fog and increase maximum colour density, especially when the emulsions contain gold, sulphur or polyethylene-glycol type chemical sensitisers. Four examples quote decamethylene-bis-benzothiazolium perchlorate (for preparation see Specification 722,237) along with couplers in the colour developers to illustrate this, and give relative speed,D-max and fog figures as compared with a control; the examples using (1) a red-sensitised emulsion, (2) and (4) multilayer materials and (3) a blue sensitive emulsion. Fifteen other thiazolium salts and numerous couplers are listed. Specifications 507,841,622,223,657,749 and U.S.A. Specification 2,566,271 also are referred to.
