Abstract (en)
The invention relates to area of colour photographic materials for registration of a colour image in visible and infra-red area. The material comprises an antihalo backing layer on the one side of a polymer support and at least two light-sensitive layers prepared from silver halide emulsion, including colour forming couplers and sensitizing dyes, auxiliary and protective gelatin layers on the other side of the polymer support, said light-sensitive layers are prepared from silver bromide-iodide emulsion with octahedral or flattened microcrystals with an average size of the grain 0,5-1,5 mu m or from their mixture and one light-sensitive layer contains as infra-red sensitizing dye one or more compounds of the formula <CHEM> where A = H, A<1> = OCH2CH2CH2SO3<->, O - lower alkyl, A and A<2> together = CH2C-(CH3)2CH2 <->, A<2> = H, lower alkyl, B = H, 5,5 '-di-OCH3, 6,6'-di-SCH3, R = lower alkyl, (CH2)3SO3<->, n = 0,1; X = CH3C6H4 SO3<->, J,-CH3SO3<->, the alkaline metal or is absent; the second light-sensitive layer contains as orthochromatic sensitizing dye more than one compounds of the formula <CHEM> where Y = 0, N, A = lower alkyl or is absent, A<1> = H, lower alkyl, B = 5,5'-COOC2H5, 5,5'-C6H5, R, R' = lower alkyl, (CH2)3SO3<->, ÄKÜ <+> = NHC5H5 or is absent and /or the third light-sensitive layer contains as panchromatic sensitizing of dye one or more compounds of the formula <CHEM> where A= lower alkyl, B = 4,5-benzo, 4,5-thieno, B<1> = 5-OCH3, 5-C6H5, 4',5'-benzo, 5-Cl, 5-CH3 ; R, R<1> = lower alkyl, (CH2)3SO3<->, ÄKÜ<+> = HN (C2H5)3, HN(C4H9)3, C5H5-NH, the alkaline metal, 3,3'-diethylthiazolynecarbocyanine, or is absent, and between light-sensitive layers auxiliary gelatin layers including hardener are coated. In addition the light-sensitive layers can contain activators of spectral sensitization. The auxiliary gelatin layers can include derivatives of triazine-1,3,5 as a hardener. It is desirable to add into light-sensitive layers a mixture of silver bromide-iodide photographic emulsions with octahedral microcrystals and with flattened microcrystals in the ratio 1:9-9:1. The material according to the invention has a high resolving power (R = 110-160 mm<-1>), i.e. in 1,6-2,3 times higher, than prototype, and more high light sensitivity.
