A photosensitive black matrix material containing an alkali soluble polymer, a photopolymerizable polyfunctional (meth)acrylate or mixture thereof, a silica coated metal oxide pigment to block light, a trialkoxyorganosilane coupling agent, a photoinitiator, sufficient solvent to render the composition spin coatable and less than 3 wt % of a dye soluble in the solvent. The resulting composition is useful for forming black matrices for display panels such as flat panel displays. The process for forming the composition consisting of mixing the ingredients is also claimed. |
