COMPOSITION FOR VISIBLE-LIGHT TRANSPARENT MATERIAL WITH PHOTOCORRECTIVE PROPERTIES Russian patent published in 2003 - IPC

FIELD: light sensitive materials. SUBSTANCE: invention relates to (co)polymer and/or oligomer compositions and concerns composition for preparation of luminescent materials and those selectively absorbing optical emission. Composition for visible-light transparent coating with photocorrective properties contains (co)polymer and/or oligomer in solvent (95.0-99.9%) and chemical additive (0.01-5.0%) with photocorrective properties containing complex compound with general formula [A(COO)_x]₃Eu•B, where A represents alkyl radical having 1-4 carbon atoms, x basicity of acid (1 or 2), and B represents substance forming with europium compound selected from 1,10-phenanthroline, α,α-dipyridyl, picoline, tetrahydrofurane, dihexylsulfoxide, quinoline and its derivatives, and anthracene and its derivatives. Solvent is an organic solvent or water. Weight ratio of (co)polymer and/or oligomers to organic solvent is (9.9-35.0):(60.0-90.0). Chemical additive can be europium carboxylate and, additionally, organic or mineral luminophores in total amount up to 5%. EFFECT: increased light transmission and UV emission absorption capacity. 5 cl, 2 tbl, 31 ex
