<P>PROBLEM TO BE SOLVED: To provide a method for producing a compound containing an unsaturated group and capable of suppressing the formation of precipitate. <P>SOLUTION: A compound containing an unsaturated group is produced by reacting epoxy acrylate with an acid anhydride in a solvent containing a dialkylene glycol monoalkyl ether. The dialkylene glycol monoalkyl ether is preferably expressed by formula (1): R<SP>1</SP>-O-C<SB>n</SB>H<SB>2n</SB>-O-C<SB>n</SB>H<SB>2n</SB>-OH (R<SP>1</SP>is a 1-8C straight chain, branched or cyclic alkyl group or an aryl group; and n is an integer of 2-5). <P>COPYRIGHT: (C)2007,JPO&INPIT |
