Beschreibung
Zusammenfassung:	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. La présente invention concerne un matériau pour matrice noire photosensible contenant un polymère soluble alcalin, un (méth)acrylate polyfonctionnel photopolymérisable ou un mélange des deux, un pigment à base d'oxyde métallique revête de silice capable d'arrêter la lumière, un trialcoxyorganosilane intervenant comme agent de couplage, un photoamorceur, une quantité suffisante de solvant pour permettre l'application par centrifugation, et une masse inférieure à 3% d'un colorant soluble dans le solvant. Cette composition convient particulièrement à la confection de matrices noires pour écrans plats. L'invention concerne également le procédé d'élaboration de la composition par mélange des ingrédients.
