Abstract

1,099,417. Incorporating photographic ingredients into colloids. GEVAERT-AGFA N. V. Jan.25, 1965, No.3152/65. Heading G2C. A colour coupler or mask-forming compound is incorporated into a hydrophilic photographic colloid by forming a solution of the coupler or compound in tetrahydrofuran, blending the solution with the colloid and removing all the tetrahydrofuran. The colloid may be a light-sensitive silver halide emulsion or it may be a colloid which is subsequently added to a light-sensitive silver halide emulsion. The tetrahydrofuran may contain formamide and/or tetrahydrothiophen-1: 1-dioxide and other solvents such as ethanol, isopropanol and ethylene glycol monomethyl ether, and may be removed by washing the colloid, by evaporation under vacuum or by evaporation after coating the emulsion composition. Moistening agents such as saponin, aryl-alkyl sulphonates and polyoxyalkylene compounds may also be present. Colloids specified are gelatine, polyvinyl alcohol, zein and casein.
