A urethane oligomer according to a) or b) has: a) at least two backbone residues R issued from a polyisocyanate without the NCO groups, linked between them with a diol residue R(diol without the two OH groups) by two urethane bonds and each backbone residues R carrying (or linked to) at least two urethane segments each containing at least one terminal allyl group, b) at least one backbone residue R issued from a polyisocyanate without the NCO groups, the backbone residue R carrying (or linked to) at least two urethane segments each linked to R by one urethane bond with at least one urethane segment (arm) containing at least one terminal allyl group, and at least one urethane segment (arm) containing at least one terminal (meth)acrylate group. A curable composition containing the urethane oligomer reduces oxygen inhibition in coatings, adhesives, sealants or in resin matrix with good surface properties.

A polyurethane (meth)acrylate oligomer, having a tri-block symmetric structure BAB, comprises a polyether central block A linked by two urethane bonds to respectively two terminal hydrophobic blocs B based on hydrophobic polyester oligomers having a terminal (meth)acryloyloxy alkylene group. A curable composition (1k) comprises the oligomer and may be used for soft touch coatings in electronics, consumer goods and vehicle manufacture, as the resulting cured soft touch coating.
