Abstract

1378171 Photographic process AGFAGEVAERT 20 Dec 1971 [5 Jan 1971] 479/71 Heading G2C In a method of producing photographic colour images by imagewise exposing a photographic silver halide element and colour developing the element with an aromatic primary amino colour developing agent in the presence of a colour forming coupler, the development is carried out at a temperature of at least 30‹C and the photographic element contains a composite light-sensitive layer of a mixture of two independently prepared silver halide emulsions one of which is capable of producing a visible image by an exposure and subsequent development as above and the other of which is a silver chloride-containing emulsion whose speed is so low that no visible image is produced therein by the said exposure and development. The mixed emulsion may contain phenol or α-naphthol type colour couplers which on development produce a dye absorbing mainly in the red and green areas of the visible spectrum. The image forming emulsion may be silver chloride, silver bromide, silver chlorobromide, silver bromoiodide, and silver chlorobromoiodide. The non-image forming emulsion may be pure silver chloride or silver chlorobromide. The emulsion may contain conventional sensitizers stabilizers, anti-foggants, hardening agents, plasticizers and screening dyes. The developer may contain development accelerators, hardening agents, anti-foggants, silver halide solvents and toning and intensifying compounds. Examples of all the above substances are given. The emulsion may be coated on both sides of a transparent resin support. The low speed emulsion prevents the gradation being reduced by rapid development at elevated temperatures.
