Title:
COATING COMPOSITION AND DECORATIVE SHEET USING THE SAME
Document Type and Number:
Japanese Patent JP2020128486
Kind Code:
A
Abstract:
To provide a coating composition which maintains transparency and ultraviolet shielding properties of a coating film and can suppress the occurrence of bleeding without deterioration of a coating film caused by the oxidative decomposition action of zinc oxide.SOLUTION: There is provided a coating composition which is a two-liquid type coating composition comprising a composite resin in which a polysiloxane segment having an epoxy group and a vinyl-based polymer segment are bonded by a specific bond, a polyisocyanate as a curing agent and zinc oxide having an average particle diameter of 0.5 to 250 nm, wherein the mass ratio of the polysiloxane segment (a1) in the solid content of the composite resin (A) is 20 to 70 mass%, the epoxy equivalent of the solid content of the composite resin (A) is 900 to 17000 g/eq, the hydroxyl value of the vinyl-based polymer segment (a2) is 50 to 200 mgKOH/g and the mass ratio of the polyisocyanate (B) is 5 to 50 mass% in the solid content.SELECTED DRAWING: None
