Colored filter element containing layers of polymerizable composition

Claim 1

A color filter prepared by providing red, green and blue image elements, comprising a photosensitive resin and a pigment, and a black matrix on a transparent substrate and further providing a transparent electrode layer either on the image elements thus formed or on said transparent substrate, said photosensitive resin comprising a polyfunctional acrylate monomer, an organic polymer binder and a photopolymerization initiator, said photopolymerization initiator consisting of at least one member selected from the 2-mercapto-5-substituted thiadiazole compounds represented by the following general formula (I) and/or general formula (II), a phenyl ketone compound represented by the following general formula (III), and a 2,4,5-triphenylimidazolyl dimer composed of two lophine residues combined to each other through intermediation of a single covalent bond: ##STR7## wherein R 1 represents alkyl group, alkylthio group or aralkylthio group, and R 2 represents substituted or unsubstituted alkylene group; ##STR8## wherein X 1 , identical or different, represents hydrogen atom, alkyl group having 1 to 6 carbon atoms, alkoxycarboxy group having 1 to 6 carbon atoms, alkoxycarbonyl group having 1 to 6 carbon atoms, alkyl-disubstituted-amino group having 1 to 6 carbon atoms or halogen atom, and R 3 represents hydrogen atom or a group represented by the following general formula (IV): ##STR9## wherein Y represents single bond or a group of the following formula ##STR10## wherein R 4 represents hydrogen atom or OR 5 , and R 5 represents hydrogen atom or alkyl group having 1 to 6 carbon atoms.
