<p>A compound represented by the following formula:- <CHEM> wherein R is a C3-C24 olefinically unsaturated organic radical having functionality which renders the nitrogen atom electron deficient, the olefinic unsaturation functionality being polymerizable, R<1> is hydrogen or a C1-C4 alkyl radical, or R and R<1> together with the nitrogen atom can form an olefinically unsaturated 5 to 7-member ring which has functionality that renders the nitrogen atom electron deficient and the olefinic unsaturation functionality is polymerizable, R<2> and R<3> are hydrogen, a C1-C4 alkyl or acyl radical, or R<2> and R<3> together are a C2-C4 alkylene group, R<4> is hydrogen or a C1-C4 alkyl, acyl, ester, amide or acid group, and n is an integer from 1 to 10, provided n is not 1 when R is (meth)acryloyl, R<2> and R<3> are methyl and R<1> and R<4> are hydrogen.</p> |
