SPECTROREGIONAL SILVER HALIDE COLOR MATERIAL Russian patent published in 2000 - IPC

FIELD: photographic materials for recording color image in visible and infrared regions. SUBSTANCE: material has polymeric substrate carrying on one side anti-halation counter-layer and on other side, at least two light- sensitive layers made of silver halide photographic emulsion including color component and sensitizing dyes, auxiliary layer, and gelatin layers; novelty is that all light-sensitive layers are composed of silver bomiode emulsion in which size of silver halide microcrystals d = 0.7-1.2 mcm with Ag1 content of 3.0-4.0 mole percent; first light-sensitive layer has infrachromatic sensitizing dye of one or more compounds of formula (1), where A, A¹, A², B, R, n, X are given in clause 1 of formula given in description of invention; second light-sensitive layer has panchromatic sensitizing dye of one or more compounds of formula (II), where A, B, R, R¹, K are given in clause 1 of formula, and/or third light-sensitive layer has orthochromatic sensitizing dye of more than one compound of formula (III), where A¹, B, R, R¹, K⁺ are given in clause 1 of formula; protective gelatin layer has, in addition, color components or their mixture. EFFECT: improved resolution and light sensitivity of material. 3 cl, 1 tbl, 14 ex
