| 摘要 |
<p>The invention relates to a polymer having at least one group derived from a carboxylic ester of a hydroxyalkylamide and an α, β-ethylenically unsaturated carboxylic acid and a radiation curable composition comprising this polymer. A coating composition comprising this composition has a high rate of polymerisation and results in coatings having the desired chemical and mechanical properties.</p> |
