Abstract:
A resin solution composition for paints or adhesives which comprises an acid-modified butene-1/&agr;-olefin copolymer obtained by modifying a butene-1/&agr;-olefin copolymer with an unsaturated carboxylic acid or an acid anhydride thereof,wherein the butene-1/&agr;-olefin copolymer comprises 65 to 85 mol % butene-1 component and 15 to 35 mol % &agr;-olefin component as polymerizable components, the &agr;-olefin component having 2 to 8 carbon atoms and being other than butene-1 component, wherein the acid-modified butene-1/&agr;-olefin copolymer has a weight average molecular weight (Mw) in the range of 50,000 to 200,000, wherein the acid-modified butene-1/&agr;-olefin copolymer comprises the unsaturated carboxylic acid or the acid anhydride thereof in a proportion of 0.5 to 5% by weight, and wherein the acid-modified butene-1/&agr;-olefin copolymer is dissolved in an organic solvent, in a solid content of 10 to 30% by weight.
