BLACK MATRIX FOR COLOUR FILTERS

摘要

Actinically modifiable composition 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, preferably = 1.2 and more preferably = 1.4 in the entire wavelength range 430 - 650 nm per 1 µm layer thickness; and ° the colorant or 50 - 100% by weight, preferably 60 - 100% by weight and more preferably 70 - 100% by weight of the colorant mixture comprises a colorant obtainable by reaction of a compound of the formula (i) with a compound of the formula (ii) in a molar 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, wherein the black colorant is likely a product of the formula (iii) or a tautomer or isomer thereof. Likewise claimed are the use of this composition for producing colour filters, colour filters themselves and also a process for producing colour filters.
