Abstract: The present invention relates to thermosetting powder coating compositions comprising of at least one bismuth-containing inorganic pigment, at least one organic phosphorous stabilizer, at least one thermally polymerizable thermosetting powder coating resin and at least one crosslinker. The inventive thermosetting powder coating compositions are advantageously used where there is a need for heat resistant coatings and where only minor surface modifications during over bake conditions are acceptable. The invention also relates to the use of the inventive thermosetting powder coating compositions for the preparation of powdered paints and varnishes for the making of coatings and to coatings obtained therewith.

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.
