Photosensitive trihalomethyl-s-triazine compound and photopolymerizable composition

Abstract

A photosensitive trihalomethyl-s-triazine compound and a photopolymerizable composition containing the photosensitive trihalomethyl-s-triazine compound. The photosensitive trihalomethyl-s-triazine compound is represented by formula (I): ##STR1## wherein X represents a chlorine atom or a bromine atom; Y represents an alkyl group, a CF.sub.3 group, a CF.sub.2 Cl group, an alkyl group substituted with a group or an atom other than hydrogen atoms, a C.sub.6 F.sub.5 group, or a group represented by --Z--CO--OR.sup.3 or --C.sub.6 H.sub.4 --R.sup.4, in which R.sup.3 represents a hydrogen atom or alkyl group, Z represents --C.sub.2 H.sub.4 --, --C.sub.3 H.sub.6 --, --CH.dbd.CH--, or o-phenylene group, and R.sup.4 represents a hydrogen atom, a hydroxyl group, an alkyl group, a substituted alkyl group, an aryl group, an alkoxy group, a substituted alkoxy group, a halogen atom, an alkoxycarbonyl group, a cyano group, an acyl group, a nitro group, a formyl group, a mercapto group, an alkylthio group, or a dialkylamino group; R.sup.1 and R.sup.2 each independently represent a hydrogen atom, a hydroxyl group, an alkyl group, an aryl group, an alkoxy group, a substituted alkoxy group, an acyloxy group, a halogen atom, an alkoxycarbonyl group, a cyano group, a nitro group, a carboxyl group, or a group represented by formula (II) or (III): ##STR2## wherein R.sup.5 and R.sup.6 each independently represent a hydrogen atom, an alkyl group, a substituted alkyl group, or a substituted aryl group, ##STR3## wherein R.sup.7 and R.sup.8 each independently represent a hydrogen atom, an alkyl group, a substituted alkyl group, an aryl group, a substituted aryl group, or an acyl group, and wherein R.sup.5 and R.sup.7 may be connected to R.sup.6 and R.sup.8 respectively, to form a ring.
