Abstract:
A composition for an anti-reflective coating or a light absorbing coating containing a polymer represented by general formula I: ##STR7##whereinR represents a hydrogen atom or an alkyl group; R.sub.1 represents an alkylene group, a substituted alkylene group, a cycloalkylene group, a substituted cycloalkylene group, a phenylene group or a substituted phenylene group; R.sub.2 represents an optionally substituted, vinyl group-containing phenyl group, --OR.sub.4 or --COOR.sub.4, in which R.sub.4 represents an alkyl group having a double bond or epoxy group; R.sub.3 represents a halogen atom, a cyano group, an acetate group, --COOH, --CONH.sub.2, a substituted or non-substituted phenyl group, --COOR.sub.5 or --OR.sub.5, in which R.sub.5 represents a substituted or non-substituted straight-chained, cyclic or branched alkyl group, or an alkyl or aryl group containing an ester or carbonyl group; X is either O or S; Y is either O or NR.sub.6 group in which R.sub.6 is a hydrogen atom or a substituted or non-substituted phenyl or cyclic, straight-chained or branched alkyl group; D is an organic chromophore which absorbs the exposed wavelength (100-450 nm) and represents a substituted or non-substituted, anthracene, anthraquinone, acridine, azobenzene, fluorene, fluorenone, carbazole, N-alkylcarbazole, dibenzofuran, phenanthrene, or pyrene, bound directly or through an alkylene group; and m and n are any numbers greater than 0 and o is any number including zero.
