METHOD OF PREPARING PHOTOGRAPHIC SILVER HALIDE MATERIAL Russian patent published in 2007 - IPC G03C1/06 G03C1/30 

Abstract SU 1840624 A1

FIELD: light-sensitive materials.

SUBSTANCE: method resides in that, prior to be coated with phloroglucinol, sublayered substrate of silver bromide-iodide emulsion is coated with protective layer composition including, g/L: gelatin 20-40, moistener 0.4-1.6, formalin 0.4-1.6, malonic acid N,N,N',N'-(tetraisopropoxymethyl)diamide 0.5-2.5, 1,4-diglycidyl-3-methyl-1,2,4-triazol-5-one 0.5-2.5, disodium phosphate 1.5-4.5, and water the rest.

EFFECT: raised deformation temperature, reduced moisture capacity of emulsion layer, and preserved water content in emulsion before being applied onto substrate.
