Abstract
Abstract An aqueous coating composition which comprises (A) at least one aqueous resin selected from acryl, alkyd, polyester, acryl-modified alkyd and acryl-modified polyester resins, (B) at least one component selected from water-insoluble resinous particles having an average grain diameter of 0.01 to 0.1 mu , obtained by a polymerization of ethylenically unsaturated compound(s), and (C) optional additives, the weight ratio of said (A) to (B) (in solid) being 99:1 DIFFERENCE 15:85. This aqueous paint is especially useful as a top-coat.

Claim 1
Independent Claim
69 words
An aqueous coating composition comprising: (A) at least one aqueous resin selected from the group consisting of acryl resins, alkyd resins, polyester resins, acryl-modified alkyd resins and acryl-modified polyester resins and (B) at least one component selected from water-insoluble resinous particles having an average grain diameter of 0.01-0.1μ, obtained by polymerization of at least one ethylenically unsaturated compound, the solid weight ratio of said (A) to (B) being 99:1-15:85.
Claim 2
Dependent Claim
69 words
An aqueous coating composition comprising: (A) at least one aqueous resin selected from the group consisting of acryl resins, alkyd resins, polyester resins, acryl-modified alkyd resins and acryl-modified polyester resins and (B) at least one component selected from water-insoluble resinous particles having an average grain diameter of 0.01-0.1μ, obtained by polymerization of at least one ethylenically unsaturated compound, the solid weight ratio of said (A) to (B) being 99:1-15:85.
