摘要 |
<p>Photocurable coating compositions comprising polyfunctional ethylenically unsaturated cellulosic polyesters having an average of at least 1.5 terminal alpha,beta-ethylenic unsaturations per substituted position of anhydroglucose unit of the polymer, a process for making them by reacting about 48 to about 69 weight percent of a cellulosic polymer having isocyanate-reactive hydroxyl functionality with about 52 to about 31 weight percent of a hydroxyl-reactive poly(alpha, beta-ethylenically unsaturated) isocyanate produced from a polyisocyanate having an average of at least three hydroxyl-reactive isocyanate groups, and their use as curable coatings, are disclosed.</p> |
