Abstract:
1. Actinically modifiable composition for producing a black matrix comprising, all based on the entire composition, 10-70% by weight of a colorant or a mixture of colorants; 90-30% by weight of actinically reactive binder material consisting of components selected from the group consisting of binders, binder precursors, dispersants, photoinitiators and stabilizers, although optionally from 0% to 30% by weight of the actinically reactive binder material can be non-reactive components; and 0-10% by weight of further, non-reactive constituents; characterized in that the composition has an optical density 1.0, in the entire wavelength range 430-650 nm per 1 μm layer thickness; and the colorant or 50-100% by weight, the colorant mixture comprises a colorant obtainable by reaction of a compound of the formula with a compound of the formula in a molar ratio of 1:2, or by reaction of a compound of the formula with 2 to 5 compounds of the formula in a molar (i):(iii) overall ratio of 1:2, in the presence of a catalyst having a pK value≦4.5 in water at 25° C., or a mixture of such colorants, where R R R or R 3 and R 4 , R 4 and R 5 or R 5 and R 6 in pairs together form a C 1 -C 6 alkylenedioxy, C 3 -C 6 alkylene, C 3 -C 6 alkenylene or 1,4-butadienylene radical, each unsubstituted or substituted one or more times by F, OR 8 , NO 2 , oxo, thioxo or SO 3 H; R each R or two vicinal R or two geminal or vicinal R each R or two vicinal R or two geminal or vicinal R R R R
