PURPOSE: To improve the misting, film strengths, and gloss by compounding a specific resin, a monomer having a radical-polymerizable double bond, and a radical polymn. initiator.
CONSTITUTION: An epoxy compd. (e.g. a glycidyl ether epoxy resin) is reacted with a monocarboxylic acid component contg. a monocarboxylic acid having a branched alkyl (ester) group (e.g. isomyristic acid) in an amt. of 0.1-1mol per mol of the epoxy group of the epoxy compd. in the presence of an amine catalyst (e.g. triethylenediamine) at 220-280°C under nitrogen blowing to give a resin. 5-60wt.% resulting resin is compounded 95-40wt.% monomer having a radical-polymerizable double bond [e.g. neopentyl glycol di(meth)acrylate] and, if necessary, 1-30wt.% radical polymn. initiator (e.g. benzoin).
