NUCLEATED HIGH CONTRAST PHOTOGRAPHIC ELEMENTS CONTAINING THIOETHER COMPOUNDS TO INHIBIT PEPPER FOG AND RESTRAIN IMAGE SPREAD

摘要

Silver halide photographic elements which are capable of high contrast-development and are especially useful in the fieldof graphic arts have incorporated therein a hydrazine compound which functions as a nucleator, an amino compound whichfunctions as an incorporated booster. and a thioether compound which functions to inhibit pepper fog and restrain image spread.
