Abstract:
Low VOC thermosetting polyester acrylic resins are made by esterification of unsaturated epoxide such as glycidyl methacrylate, and a polyacid which is the half-ester formed by reacting an acid or its anhydride with a polyol is disclosed. The obtained low viscosity resin is useful for making a low or zero VOC gel coat with excellent hydrolytic and weather resistance.

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.
