Abstract
A coat resin composition comprising a polyester (A) comprising an acid component comprising an aromatic dicarboxylic acid in a proportion of 50-100% by mole relative to the entire acid component and other carboxylic acid(s) in a proportion of 50-0% by mole relative to the entire acid component, and a glycol component comprising 2-methyl-1,3-propanediol and/or 1,3-propanediol in a proportion of 1-25% by mole relative to the entire glycol component and an alkylene glycol having 5 to 10 carbon atoms in a proportion of 75-99% by mole relative to the entire glycol component, or an alicyclic glycol in a proportion of 20-85% by mole relative to the entire glycol component, an addition product of bisphenol A with alkylene oxide in a proportion of 80-15% by mole relative to the entire glycol component and other glycol(s) in a proportion of 0-50% by mole relative to the entire glycol component, wherein the total of the glycols is 100% by mole, the polyester (A) having a reduced viscosity of not less than 0.2 dl/g; and a curing agent (B) reactive with the polyester (A), in a proportion of (A)/(B)=99/1--50/50 (weight ratio). The present invention provides coating resin compositions capable of …
