METHOD FOR PREPARATION OF SILVER HALIDE PHOTOEMULSION SPECTER SENSITIZER COMPOSITIONS

摘要

FIELD: photographic material production. SUBSTANCE: sensitizer is solved in a low-boiling water immiscible organic solvent. Then the resultant solution is mixed with a polymer in the proportion of 1 to 5-10. The polymer is formulated as where R = H, CH₃; n = 0.02-0.15; m = 0.98- 0.85. The polymer molecular mass is 2000-5000. Then the solution is dispersed in a 3% water-and-gelatin solution. The resulting composition is stable during up to 30 days. EFFECT: increased stability. 1 tbl
