Abstract
Official abstract text for this publication.
The present invention relates to a matte coating agent containing 1 to 150 parts by mass of resin particles A having a volume average particle diameter of 1 to 5 μm, 1 to 150 parts by mass of resin particles B having a volume average particle diameter of 5 to 10 μm, and 1 to 150 parts by mass of resin particles C having a volume average particle diameter of 10 to 20 μm based on 100 parts by mass of a polyurethane resin, the total content of the resin particles A, the resin particles B, and the resin particles C being 3 to 250 parts by mass based on 100 parts by mass of the polyurethane resin, and the volume average particle diameter becoming larger sequentially from the resin particles A to the resin particles B to the resin particles C.
First claim

1 . A matte coating agent, comprising: 1 to 150 parts by mass of resin particles A having a volume average particle diameter of 1 to 5 μm, 1 to 150 parts by mass of resin particles B having a volume average particle diameter of 5 to 10 μm, and 1 to 150 parts by mass of resin particles C having a volume average particle diameter of 10 to 20 μm based on 100 parts by mass of a polyurethane resin, wherein the total content of the resin particles A, the resin particles B, and the resin particles C is 3 to 250 parts by mass based on 100 parts by mass of the polyurethane resin, and wherein the volume average particle diameter becoming larger sequentially increases from the resin particles A to the resin particles B to the resin particles C. 2 . The matte coating agent according to claim 1 , further comprising: 1 to 20 parts by mass of a silica A having a volume average particle diameter of 1 to 5 μm and 1 to 20 parts by mass of a silica B having a volume average particle diameter of 5 to 15 μm based on 100 parts by mass of the polyurethane resin, wherein the volume average particle diameter of the silica B being is larger than the volume average particle diameter of the silica A. 3 . The matte coating agent according to claim 1 , wherein the resin particles A, the resin particles B, and the resin particles C are polyurethane resin particles. 4 . The matte coating agent of claim 1 , further comprising an aqueous solvent. 5 . A skin material, comprising: a thermoplastic resin base material having a film comprising the matte coating agent of claim 1 .
