Method of incorporating photographic adjuvants into hydrophilic colloids
Abstract
Abstract A photographic chemical compound in incorporated into a hydrophilic colloid composition by dispersing a solution of the chemical compound in the hydrophilic colloid composition in the presence of a surface active compound of the formula : WHEREIN : N IS 0 OR 1 AND M IS 0 TO 30, R3 is hydrogen or when n is 1 may be alkyl, R2 and R3 stand for straight-chain or branched-chain alkyl groups or together are the atoms necessary to complete an alicyclic ring structure, R1 and R2 comprising at least eight C-atoms, and Z is a group -SO3M, -OSO3M, -OCOXSO3M or -Y-A-SO3M wherein M is hydrogen, alkali metal, ammonium or organic ammonium X is alkylene, aralkylene or arylene, Y is oxygen or sulphur, and A is alkylene or aralkylene. The colloid composition can be a light-sensitive silver halide emulsion or a non-light-sensitive water-permeable colloid composition.
