Abstract
This invention offers a coating resin composition which exhibits excellent drawing processability, processability and hardness and forms a coat having good processability, hardness, scuff resistance, impact resistance, stain resistance and blocking resistance even in clear or low pigment concentration. Disclosed herein is a coating resin composition containing a polyester resin (A) which has a glass transition point of 10-80.degree. C., reduced viscosity of not less than 0.2 dl/g and specific gravitity of 1.21-1.30 and mainly comprises aromatic dicarboxylic acid including terephthalic acid, 2-methyl-1,3-propanediol and/or 1,3-propanediol and alkylene glycol with 5-10 carbon atoms and/or alicyclic glycol and a hardener (B) which is reactive with said polyester resin (A).
