Document Type and Number:
Japanese Patent JP4041968
Kind Code:
B2
Abstract:
A primer composition comprises a vinyl copolymer obtainable through copolymerization of ultraviolet-absorbing vinyl monomer (5-40 wt.%); alkoxysilyl group-containing vinyl monomer (1-50 wt.%) and other monomer copolymerizable with the above monomers (10-94 wt.%); curing agent capable of reacting with the vinyl copolymer; and thermoplastic vinyl resin having a glass transition temperature of >=80[deg]C. Independent claims are also included for: (a) a method for providing a plastic substrate with a weather resistant, abrasion resistant coating, comprising applying an organic solvent solution of a primer composition as above onto a plastic substrate; evaporating the solvent and curing the primer coating; applying an organopolysiloxane composition to the primer coating, comprising a hydrolysate or co-hydrolysate of an organooxysilane having a general formula (R 4>) mSi(OR 5>) 4 - m; and heating at a temperature enough for the composition to cure; and (b) a resin coated article comprising resin layers, where a first layer that is contiguous to the substrate is a cured resin layer of a primer composition as above, and a second layer that is contiguous to the first layer is a cured resin layer of an organopolysiloxane composition comprising a hydrolysate or co-hydrolysate of an organooxysilane as above, and optionally colloidal silica. R 4>1-10C organic group; R 5>H or a monovalent organic group; m : 0, 1 or 2.
