ABSTRACT:
A compound represented by the following general formula (1): (1) wherein A represents an alkenyl ether group which may be substituted; B represents a linear or branched alkylene group having 1 to 15 carbon atoms which may be substituted; m represents an integer from 0 to 30; when m is larger than 1, B may be different from each other; D represents a single bond or a linear or branched alkylene group having 1 to 10 carbon atoms which may be substituted; E represents any one of an aromatic ring which may be substituted, a condensed ring which may be substituted, and a structure formed by bonding through single bonds at most three aromatic rings which may be substituted; R represents a hydrogen atom, a linear or branched alkyl group having 1 to 5 carbon atoms which may be substituted, or an aromatic ring which may be substituted; n represents a positive number larger than 1; a COOR group in the formula is substituted into the aromatic ring of E; and a hydrogen atom in the aromatic ring, which is not substituted with COOR, may be substituted.
