ABSTRACT:
A process for producing a curable resin is provided which comprises the steps of polymerizing a five-member cyclic compound (A) having an unsaturated conjugated double bond and represented by the general formula (A) given below; ##STR1## (wherein R is an organic residue having from 1 to 3 carbon atoms; m and n are integers and are in the relation of m+n=6)
or Diels-Alder addition product thereof (A) with at least one phenolic compound (B) selected from the group consisting of monohydric and polyhydric phenols and alkyl substituents thereof to obtain a resin (I) having at least one phenolic hydroxyl group and an average molecular weight of from 300 to 2000; hydrogenating said resin (I) to convert the aromatic ring of the phenolic compound unit into the cyclohexane structure thereby to obtain a resin (II); and esterifying said resin (II) with an .alpha., .beta.-unsaturated carboxylic acid (C). A curable coating composition is also provided which comprises as vehicle the above curable resin.
