Description

(54) LIGHT-SENSITIVE COMPOSITION

The invention relates to photosensitive compositions and recording materials based on them, in particular for the mapping industry. A photosensitive composition comprising a ferrocene, a halogen hydrocarbon and a solvent is known. It makes it possible to obtain on paper or plastic yellow-brown and violet copies that are easily washed off with water and with solvents such as alcohol, acetone, etc. The disadvantages of this composition are the low quality of the reproductions obtained, the instability of the images, the easy washability of them with water and other solvents, and the lack of density of the images that make it difficult to re-reproduce. The purpose of the invention is to improve the clarity and stability of copies of various colors of improved quality based on ferrocene-containing photosensitive compositions. It is proposed to introduce ferropen in the photosensitive composition as a ferrocene compound, an electron-donor and / or electron-withdrawing substitutions, such as a monostil-monoacetyl dystil-diacetyl or Y, K-dimethyl-aminoferrocene and additionally a tinting compound, indole, and / or p-naphthol, and / or resorcinol in the following proportion of components, wt.%: Ferrocene, containing an electron-donating and / or electron-withdrawing substituent1-35 Halogenated hydrocarbon 0.5-35 Toning compound 0.1-50 Solvent Remaining B Acetone, methyl ethyl ketone, gasoline, hectane, alcohol or water are used as solvents. On the basis of such a photosensitive composition, negative (positive) images can be obtained on paper of various grades (drawing, printing, Whatman paper), plates (polyester, polyethylene, hostafan, etc.), plates with an engraving layer or metals- (aluminum and zinc plate). Use in the composition of poorly water-soluble ferrocene compounds provides

clear images, indelible water and solvents (gasoline, alcohol 1 deton). Toning additives make it possible to obtain on the same recipes copies of different colors (green, red, brown, violet, black), which can be used to obtain multi-color images (for example, in the map printing industry).
