Abstract
A color filter array element, preferably for use in a color electro-optical display device such as a liquid crystal display device, comprises a support having thereon a polymeric dye image-receiving layer containing a thermally transferred image comprising a repeating pattern of colorants and a photopolymerizable overcoat layer. Areas of the overcoat layer which have not been subjected to conditions that effect polymerization of the layer are selectively removable together with the corresponding underlying areas of the image-receiving layer. In a preferred embodiment the photopolymerizable overcoat layer contains at least about 25 weight percent of 3,4-epoxycyclohexylmethyl-3,4-epoxycyclohexylcarboxylate and at least about 4 weight percent of a triarylsulfonium salt.
