    Abstract: A urethane (meth)acrylate oligomer which has a low viscosity and gives a flexible cured product having a low surface tackiness, is provided. It is obtainable by reacting a polyol component comprising a polyoxyalkylene polyol which has from 2 to 4 hydroxyl groups, a hydroxyl value VOH (mgKOH/g) of from 5 to 115 and a total degree of unsaturation VUS (meq/g) satisfying VUS≦(0.45/VOH)+0.02, with a polyisocyanate compound and a hydroxylated (meth)acrylate compound.

    Abstract: The invention provides a photo-curable composition for manufacturing thick layers of homogeneous grey to black colour with excellent physical properties as required for use in high tech applications such as for example powder coatings. Such compositions were highly desirable but yet unachieved in the art. The instant composition comprises a radiation curable material as well as both an iron oxide and a phthalocyanine pigment. It has a lightness (L*) of from 0 to 90 and a chroma (C*) of from 0 to 30. The process of hardening said composition by irradiation with light of the wavelength from 150 to 600 nm is also claimed.
