FIELD: photographic emulsions. SUBSTANCE: method consists in introducing into emulsion (i) disodium salt of 4,4'- bis[4", 6"-diphenoxy-1"'3"'5"-triazinyl-2-amino]stilbene-2,2'- disulfonic acid and (ii) sensitizer with general formula $$$ (I) where A is lower alkyl, benzyl, aralkyl, cycloalkyl; A' two H atoms or 2,2- dimethyl-1,3-propylene; R group $$$ in which n=3,4 or lower alkyl; $$$ iodine, $$$; $$$; compound with formula $$$ (II) where D is $$$ or $$$; A lower alkyl; B 4,5-benzo, thiene group, 5-methyl, or 6-methoxy; alkali metal ion, trialkylammonium, pyridinium, 2-methyl-3- alkylbenzthiazolium, 2-methyl-1,3-dialkylbenzimidazolium, 3,3'- diethylthiazolinocarbocyanine, 1,1'-diethylquino-2,2'- monomethynecyanine, 3,3'-dipropyl-5,5'-dimethoxy-6,6'- bis(methylmercapto)-10-methyldicarbocyanine; compound with formula $$$ (III) where A is lower alkyl; B and B' are methyl, methoxy, chlorine, or phenyl; $$$ alkali metal ion, pyridinium, trialkylammonium, or dication of bis-quaternary salt of benzimidazolium having formula V, and/or sensitizer with formula $$$ (IV) where A is methyl or amino group; $$$ alkali metal ion, ammonium, pyridinium, trialkylammonium, or dication of bis-quaternary salt of benzimidazolium having formula V, and additionally supersensitizer with formula V where B and B' are hydrogen, methyl or chlorine; m=1,2; n=0.2; X is perchlorate ion or p- tosylate, in quantity 1 mol per 1 mol of each sensitizer with formulas I-IV. EFFECT: paninfrachromatic materials obtained are characterized by sensitivity level behind red filter exceeding that of infrachromatic material and have the same sensitivity level at 680 nm (panchromatic material) and at 740 nm (infrachromatic material). 2 cl, 5 tbl
