INFRACHROMATIC PHOTOGRAPHIC MATERIAL Russian patent published in 2006 - IPC G03C1/12 

Abstract SU 1840098 A1

FIELD: light-sensitive materials.

SUBSTANCE: invention relates to manufacturing photographic materials suitable for holograph construction in infrared region of spectrum. Material comprises substrate and silver halide emulsion layer with pBr 5-7 and containing emulsion with average size of silver halide microcrystals 0.03-0.08 μm; optionally chain-substituted sensitized dye 6,7,6',7'-dibenzothiatricarbocyanine; activator: bistriazinyl derivative - p,p'-diaminostilbene; O,O'-disulfonic acids; stabilizer: triazaindolicine derivative; and reducer: aminooxy- or hydroxy-derivatives of aromatic series.

EFFECT: increased resolving power and sensitivity to emission of injection lasers within a wavelength range 820-920 nm.
