LIGHT-SENSITIVE RECORDING MATERIAL Russian patent published in 2007 - IPC G03C1/735 G03C5/06 

FIELD: heat development non-silver light-sensitive recording materials, meant for producing images under effect from laser radiation or during exposition through a negative by contact or projection method.

SUBSTANCE: light-sensitive recording material is described, includes light-sensitive component - cyclopentadienyltricarbonylmanganese or its derivative; color-forming component, such as phenol, 1-naphthol, 4-alcoxynaphthol, 4-alkylnaphthol, 2-alkylnaphthol, 4-oxydiphenylamine, 4-aminephenol, or a mixture of 4-phenylenediamine or its derivative - diaminedurene, 4-diethylamineaniline, 4-aminediphenylamine or 4-amine-4-methoxydiphenylamine, with color-forming component, such as phenol, 2-methoxyphenol, 3-methoxyphenol, 4-methoxyphenol, 3-diethylaminephenol, 3,5-dimethoxyphenol, 1-naphthol, 2-athylnaphthol and 3-methyl-5-phenylpyrazolone-4; and polymer binding agent, containing no halogen or free carbonyls, or sulphogroups, ensuring penetrability for air oxygen.

EFFECT: suggested material has increased light sensitivity (up to 2,5 · 10⁴ J/cm²), features lasting preservation of properties (absence of veil for up to two years) and broad color gamma of resulting images.
