Abstract
1,045,184. Photographic silver halide materials and developers. AGFA A.G. June 1, 1964 [May 31, 1963], No. 22523/64. Heading G2C. Exposed silver halide emulsions layers in which the silver halide contains at least 50 mol per cent of silver bromide are developed in the presence of a condensation product of a compound of the formula: with at least one polyethyleneglycol having from 3 to 100 ethylene glycol units. The condensation product may be present in the silver halide layer or in the developer and increases the general sensitivity of the material.
