Title:
COATING MATERIAL FOR FORMING MATTE HARD COAT, AND DECORATIVE SHEET USING SAME
Document Type and Number:
WIPO Patent Application WO/2019/077930
Kind Code:
A1
Abstract:
The present invention relates to a coating material including (A) 100 parts by mass of an acrylic-based curable resin, (B) 5-200 parts by mass of resin particles having an average particle diameter of 0.5-20 µm, (C) 0.05-20 parts by mass of a silicone/acrylic copolymer-based oil-repellent agent, and (D) 1-100 parts by mass of a compound having two or more isocyanate groups in each molecule thereof. Preferably, the acrylic-based curable resin (A) may include structural units (a1) derived from a hydroxyl-group-containing (meth)acrylic acid ester, structural units (a2) derived from a vinyl aromatic compound, and structural units (a3) derived from a (meth)acrylic acid ester, and the acrylic-based curable resin (A) may include the structural units (a1) derived from a hydroxyl-group-containing (meth)acrylic acid ester in the amount of 5-40 mol% with respect to a total of 100 mol% of structural units derived from all the constituent monomers of the acrylic-based curable resin (A).
