Abstract

Abstract The present invention provides a process for painting a polyolefinic resin component comprising washing the surface of the polyolefinic resin component, directly coating at least one time the surface with the following paint, and forming topcoat on the surface, the paint being a mixture of a main component containing principally a polymer resin having a hydroxyl number of 20-150, which is obtained by polymerizing (A) Chlorinated polyolefin, (B) Acrylic monomer and (C) Polyester prepolymer and a curing agent of (D) polyfunctional isocyanate compound.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 144 words
A process for painting a polyolefinic component comprising washing the surface of the polyolefinic resin component, and coating the surface at least once with the following paint, the paint being a mixture comprising a polymer resin having a hydroxyl number of 20 to 150, which is obtained by polymerizing the following ingredients (A), (B) and (C), and a curing agent (D): (A) chlorinated polyolefin, 5 to 50% by weight. (B) acrylic monomer having hydroxyl groups or a mixture of the above acrylic monomer and an ethylene monomer which is able to copolymerize with the above acrylic monomer, 5 to 80% by weight. (C) polyester prepolymer having ethylene terminal double bonds and a number-average molecular weight of 500 to 3000, 1 to 50% by weight. (D) polyfunctional isocyanate compound having NCO groups per hydroxyl group of the polymer resin of NCO/OH = 0.4 to 2.0.
Claim 2
Dependent Claim 122 words
A paint for painting a polyolefinic resin component, the paint comprising a polymer resin having a hydroxyl number of 20 to 150, which is obtained by polymerising the following ingredients (A), (B) and (C), and a curing agent (D): (A) chlorinated polyolefin, 5 to 50% by weight. (B) acrylic monomer having hydroxyl groups or a mixture of the above acrylic monomer and an ethylene monomer which is able to copolymerize with the above acrylic monomer, 5 to 80% by weight. (C) polyester prepolymer having ethylene terminal double bonds and a number-average molecular weight of 500 to 3000, 1 to 50% by weight. (D) polyfunctional isocyanate compound having NCO groups per hydroxyl group of the polymer resin of NCO/OH = 0.4 to 2.0.
Claim 3
Dependent Claim 85 words
A polymer resin for use in a paint according to claim 2, the polymer resin being obtained by polymerising the following ingredients: (A) chlorinated polyolefin, 5 to 50% by weight. (B) acrylic monomer having hydroxyl groups or a mixture of the above acrylic monomer and an ethylene monomer which is able to copolymerize with the above acrylic monomer, 5 to 80% by weight. (C) polyester prepolymer having ethylene terminal double bonds and a number-average molecular weight of 500 to 3000, 1 to 50% by weight.
