Abstract
The invention describes curable liquid acryloyl group containing compositions, which are produced by reacting monofunctional vinyl compounds and multifunctional acrylic esters with β-dicarbonyl group containing compounds having two activated hydrogen atoms in its methylene position. These material can be polymerized or crosslinked by free radical polymerization, UV (ultraviolet) or electron-beam radiation. The curable liquid compositions are suitable for producing curable coatings, printing inks, adhesives, or moulding compositions.
Claims33
A curable liquid acryloyl group containing resin composition obtained by reacting
- (a) at least one monofunctional vinyl compound, and
- (b) at least one multifunctional acrylic ester, with
- (c) at least one P-dicarbonyl group containing compound or resin, in which the β-dicarbonyl group has two activated hydrogen atoms in its methylene position,
- wherein the equivalent ratio of the vinyl group of the monofunctional vinyl compound (a) to the activated hydrogen atom of the compound or resin (c) is in the range from 0.01:1 to 0.9:1 and
- the equivalent ratio of all unsaturated groups from both monofunctional vinyl compound (a) and multifunctional acrylic ester (b) to the activated hydrogen atom of the compound or resin(c) is >1.05:1.
