Development of photographic silver halide material |
| abstract |
A PROCESS IS DESCRIBED FOR DEVELOPING AN EXPOSED PHOTOGRAPHIC SILVER HALIDE ELEMENT WHEREIN THE DEVELOPMENT IS CARRIED OUT IN THE PRESENCE OF A WATER-SOLUBLE POLYMERIC COMPOUND OBTAINED BY POLYADDITION OF A DIHYDRIC ALCOHOL OF THE FORMULA HO-X-OH, X BEING ARYLENE, A STRAIGHTCHAIN OR BRANCHED-CHAIN C2-C8 ALKYLENE, C2-C8 ALKENYLENE OR C2-C8 ALKYNYLENE GROUP, CYCLOALKYLENE OR ALKYLENE-CYCLO-ALKYLENE, WITH A BISEPOXIDE OF THE FORMULA: ((-O-CH2-)>CH-CH2-O)2-Z Z BEING A STRAIGHT-CHAIN OR BRANCHED-CHAIN C2-C8 ALKYLENE GROUP. THE SPEED AND DEVELOPABILITY OF THE SILVER HALIDE ELEMENT IS SUBSTANTIALLY INCREASED BY THE PRESENCE OF THIS POLYADDITION COMPOUND. BY INFECTIOUS DEVELOPMENT OF SILVER CHLORIDE AND SILVER CHLOROBROMIDE EMULSIONS IT IS POSSIBLE BY MEANS OF THESE POLYADDITION COMPOUNDS TO OBTAIN VERY CONTRASTY LINE AND SCREEN IMAGES AND SHARPLY DEFINED SCREEN DOTS AND TO REDUCE THE FORMATION OF PEPPERS WHEN USING SOMEWHAT EXHAUSTED DEVELOPING BATHS. |
