METHOD OF PREPARING COMPOSITION FOR REGISTERING LAYER OF THERMODEVELOPING PHOTOMATERIAL Russian patent published in 1995 - IPC

Abstract RU 2041483 C1

FIELD: photographic materials. SUBSTANCE: method involves grinding silver stearate and phthalimide in isopropanol solution of polyvinylbutyral, addition to the prepared suspension of lithium bromide, reductant and optic sensibilizing agent-dye of the formula (I) where R1, R3 lower alkyl; R2- =CH-CH=C(CH3) or where X halogen. Before dye supersensibilizing agent can be added disodium salt of 4,4′-bis-(4,6-diphenoxy-1,3,5-triazinyl-2-amino)-stilbene- 2,2′-disulfoacid. EFFECT: enhanced photosensitivity of material at the wavelength range 760-860 nm. 2 cl, 1 tbl
