Abstract: Disclosed is the use of a particulate material in a polymer article, or a polymer composition containing the particulate material, in particular a masterbatch, as well as of a polymer film composition, for reducing the transmission of near-infrared radiation and for allowing transmission of visible light through the article, whereby i. the particulate material is based on crystalline titanium dioxide, ii. the particles of the particulate material are coated with an organic and/or inorganic coating layer, iii. at least 20% by weight of the particulate material particles have a particle size of at least 400 nm and at most 1000 nm, and iv. at least 1.5% by weight and at most 40% by weight of the particles in the particulate material have a particle size of less than 400 nm and at least 280 nm.

Abstract: The invention relates to hydroxy-functional (meth)acrylic copolymers having an OH value from 40 to 260 mg KOH/g, a number average molecular mass (Mn) from 1500 to 20000 g/mole and a glass transition temperature Tg from −40° C. to 80° C., containing A) polymerized monomers of at least one epoxy-functional, olefinically unsaturated monomer, B) at least one compound having a carboxyl group and at least one hydroxyl group in the molecule that is reacted with the epoxy functional group of the polymerized olefincially unsaturated monomers, C) at least one additional polymerized olefinically unsaturated monomer capable of radical polymerization which is different from component A) and D) optionally at least one lactone reacted with the polymer. It also relates to processes for making the copolymers and to coating compositions that contain the hydroxy-functional (meth)acrylic copolymers and to the use thereof in multi-layer automotive coatings.

Abstract: The invention relates to solvent-based coating compositions, comprising at least one hydroxy-functional (meth)acrylic copolymer I having an OH-value from 40 to 260 mg KOH/g, and a number average molecular mass (Mn) from 1,300 to 20,000 g/mol, which comprise the following polymerized components:
