    • Liquid coating compositions adapted to be cured by exposure to ionizing radiation are disclosed in which a liquid vehicle of coating viscosity having an ethylenically unsaturated portion comprising one or more polyethylenically unsaturated materials adapted to cure on radiation exposure, pigment dispersed in the vehicle, and an acrylate-functional radiation-curable dispersant having free carboxyl group for wetting the pigment and assisting in the stable dispersion of the pigment in the vehicle. This dispersant is an acrylate-functional carboxylic acid amide carrying free carboxyl groups, especially an adduct of a polyacrylate and a stoichiometric deficiency of a primary amine to provide a secondary amine having acrylate functionality, the secondary amine functionality being reacted with a polycarboxylic acid anhydride to form amide groups therewith.

    • This invention concerns the production of textured surfaces, and in particular to compositions for producing such surfaces. The compositions include a radiation-curable component, an adhesion promoter for promoting adhesion to a substrate, and a texture-modifying amount of microspheres substantially homogeneously dispersed therein. The microspheres can be of glass, ceramic or polymeric materials, and they can be solid or hollow. Various adhesion promoters can be used, and in general the choice will depend upon the curable system used. For example, certain polymers, monomers or unreactive volatile solvents can be used as adhesion promoters with free-radical curable compositions. Texturing can be effected on the surface of a variety of materials, for example on plastics or cellulosic substrates.
    • 本发明涉及纹理表面的生产,并且特别涉及用于生产这种表面的组合物。 该组合物包含可辐射固化组分,用于促进与基底粘合的粘合促进剂,以及基本均匀分散于其中的结构改变量的微球。 微球体可以是玻璃,陶瓷或聚合物材料,它们可以是实心或空心的。 可以使用各种助粘剂,并且通常选择取决于所用的可固化体系。 例如,某些聚合物,单体或非反应性挥发性溶剂可用作具有自由基可固化组合物的增粘剂。 可以在多种材料的表面上进行纹理化,例如在塑料或纤维素基材上。
