POLYNUCLEAR EPOXY COMPOUND, RESIN OBTAINED THEREFROM CURABLE WITH ACTINIC ENERGY RAY, AND PHOTOCURABLE/THERMOSETTING RESIN COMPOSITION CONTAINING THE SAME

WIPO Patent Application WO/2001/053375

A1

A linear polynuclear epoxy compound comprising regular repetitions of aromatic rings of different kinds, especially one having a high softening point which is an alternating copolymer in which a biphenyl or bisphenol skeleton and a naphthalene skeleton occur alternately. By reacting the polynuclear epoxy compound with a monocarboxylic acid having an unsaturated group, a linear polynuclear epoxy acrylate compound is obtained which is photocurable and thermosetting. Furthermore, by reacting the polynuclear epoxy acrylate compound with a polybasic acid anhydride, a resin is obtained which is curable with active energy rays and is soluble in aqueous alkali solutions. Also provided is an alkali-developable photocurable/thermosetting resin composition which comprises (A) the resin curable with active energy rays, (B) a photosensitive (meth)acrylate compound, (C) a photopolymerization initiator, and (D) a polyfunctional epoxy compound.
