<p>The invention includes compounds represented by Formula
(1) :
wherein
R represents hydrogen or methyl;
A represents alkylene having from 1 to 12 carbon atoms, wherein in the alkylene, arbitrary -CH 2 - may be replaced by -O-, -S-, -CH=CH-, -CO-, -COO- or -OCO-;
X and Y each independently represent an aromatic ring or a cyclohexane ring, wherein in the rings, arbitrary hydrogen may be replaced by alkyl having from 1 to 3 carbon atoms;
Z independently represents a single bond, -O-, -S-, -COO-, -OCO-, -CON(R 1 )- or -N(R 1 )CO-, wherein R 1 represents hydrogen or methyl; and
m represents an integer of from 0 to 3.</p> |
