Abstract
Abstract A process for forming a metallic paint film comprising (a) coating on a substrate surface a metallic paint containing as a vehicle component a modified vinyl-type copolymer obtained by copolymerizing 5-75 weight % of cellulose acetate butyrate with 95-25 weight % of a monomeric component consisting of one or more vinyl-type monomers, (b) if necessary, coating a thermosetting resin-type clear topcoating while said coated metallic paint film is in the unhardened state and (c) then baking the paint film.

Claim 1
Independent Claim
47 words
A metallic paint comprising: (a) a modified vinyl-type copolymer obtained by copolymerizing 5-75% by weight of cellulose acetate butyrate with 95-25% by weight of a monomer component consisting of one or more vinyl-type monomers, as a vehicle component, (b) a metallic powder, and (c) an organic solvent.
Claim 2
Dependent Claim
47 words
A metallic paint comprising: (a) a modified vinyl-type copolymer obtained by copolymerizing 5-75% by weight of cellulose acetate butyrate with 95-25% by weight of a monomer component consisting of one or more vinyl-type monomers, as a vehicle component, (b) a metallic powder, and (c) an organic solvent.
Claim 3
Dependent Claim
36 words
The paint of claim 1 wherein said modified vinyl-type copolymer is obtained by copolymerizing 10-50 weight% of cellulose acetate butyrate with 90-50 weight% of a monomeric component consisting of one or more of said vinyl-type monomers.
Claim 4
Dependent Claim
26 words
The paint of claim 1 wherein said cellulose acetate butyrate has a degree of acetylation of 1-34 weight% and a butyl group content of 16-60 weight%.
Claim 5
Dependent Claim
18 words
