Abstract

NEW MATERIAL:A 2-(4-dialkylaminophenyl)naphtho[1,8-bc]furan-5-one of formula I: (R is 1W6C alkyl group).
USE: Photopolymerization initiators which form photopolymerizable compositions with compounds capable of effecting addition polymerization having ethylenically unsaturated double bonds. The compound of formula I can be obtained at a low cost compared with the conventional polymerization initiators.
PROCESS: 0.1W10moles of a p-dialkylaminobenzoic acid of formula II is condensed with one mole of 1,5-dihydroxynaphthalene in a polyphosphoric acid at room temperature to 200°C to give the objective compound of formula I. Polyphosphoric acid consisting mainly of tri- and tetrametaphosphoric acids is generally used.
