ULTRAVIOLET-INSULATING COATING MATERIAL AND PROCESSED PRODUCT PROVIDED WITH ULTRAVIOLET-INSULATING FILM

摘要

PROBLEM TO BE SOLVED: To obtain a coating material in which the constituent ultraviolet- insulating agent is stably dispersed in the vehicle by using a resin powder containing a metal oxide having a specified particle diameter as the ultraviolet- insulating agent. SOLUTION: This material comprises a resin powder (B) including an ultraviolet-intercepting agent having a dispersed particle diameter of 0.03-0.1μm and a vehicle component. In particular component A is desirably zinc oxide, titanium oxide or cerium oxide. Component B is prepared by simultaneously dispersing and polymerizing a resin-forming monomer (desirably a vinyl monomer having at least two ethylenically unsaturated bonds in the molecule, such as ethylene glycol dimethacrylate). The mean particle diameter of component B containing component A is 0.1-50μm. This material gives excellent ultraviolet- intercepting coating films not problematic in poor dispersion and insufficient durability inherent in ultraviolet-intercepting coating materials containing conventional unincluded metal oxides and excellent in transparency.
