UV curable crosslinking agents useful in copolymerization

A composition having at least two different types of ethylenically polymerizable groups and having the schematic representation:

• ##STR15## wherein V denotes a vinyl-containing group having the formula:
• ##STR16## A' denotes an acrylic-containing group having the formula:
• ##STR17## S denotes a styrene-containing group having the formula:
• ##STR18## wherein R.sub.1' is an alkyl radical, polyalkylene oxide, poly(perfluoro) alkylene oxide, dialkyl-capped polydimethylsiloxane, dialkyl-capped polydimethylsiloxane modified with fluoroalkyl or fluoroether groups;
• R.sub.2' -R.sub.10' are independently H, or alkyl of 1 to 5 carbon atoms;
• Q is an organic group containing aromatic moieties having 6-30 carbon atoms;
• X, Y, and Z are independently O, NH or S;
• v' is 1, or higher;
• and
• a', s' are independently greater than or equal to 0, and a'+s' is greater than or equal to 1.
