UV curable blend compositions and processes |
摘要 |
An ultraviolet curable blend composition comprising (exclusive of any solvent present): (a) about 35% to about 65% by weight of a first acrylated aliphatic urethane having a molecular weight of between about 500 and 2000 and formed by the reaction of (i) a first multifunctional acrylate with a molecular weight of between about 190 and 500 and containing at least three polymerizable unsaturated groups per molecule, with (ii) an aliphatic urethane based on a polymer of allyl carbomonocycle diisocyanate with alkanepolyol polyacrylates; (b) about 5% to about 25% by weight of a second acrylated aliphatic urethane having a molecular weight of about 1200 to about 2600 and formed by the reaction of a second multifunctional acrylate with a molecular weight of about 110 to about 500 with an aliphatic urethane based on a polyether and having a molecular weight of about 800 to about 2200; (c) about 10% to about 55% by weight of a third multifunctional acrylate having a molecular weight of between about 170 and about 1000 and containing at least two polymerizable unsaturated groups per molecule; and (d) a photopolymerization initiator and/or sensitizer. Also described are preferred processes and coated articles involving preferred compositions.
