ABSTRACT:
An unsaturated polyester compound having an ethylenically unsatureated group in its terminal and hydroxymethyl group in its side chain is obtained by the reaction of (a) a compound containing at least two oxetane rings in its molecule with (b) a compound containing at least two carboxyl groups in its molecule and (c) an unsaturated monocarboxylic acid in the presence of a reaction promotor in such a proportion that the ratio of said compound (b) to said compound (a) falls in the range of 0.1<(b)/(a)<1. BY further reacting (d) a polybasic acid anhydride with the resultant unsaturated polyester compound (A′), there is obtained an actinic energy ray-curable resin which is soluble in an aqueous alkaline solution. A photocurable and/or thermosetting composition is obtained by mixing the unsaturated polyester compound (A′) and/or the actinic energy ray-curable resin with a polymerization initiator (B).
