Photosensitive trihalomethyl-s-triazine compound and photopolymerizable composition

摘要

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): (I) wherein X represents a chlorine atom or a bromine atom; Y represents an alkyl group, a CF3 group, a CF2Cl group, an alkyl group substituted with a group or an atom other than hydrogen atoms, a C6F5 group, or a group represented by -Z-CO-OR3 or -C6H4-R4, in which R3 represents a hydrogen atom or alkyl group, Z represents -C2H4-, -C3H6-, -CH=CH-, or o-phenylene group, and R4 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; R1 and R2 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): ntly represent a hydrogen atom, an alkyl group, a substituted alkyl group, or a substituted aryl group, (III) wherein R7 and R8 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 R5 and R7 may be connected to R6 and R8 respectively, to form a ring.
