PURPOSE:To obtain a polyester excellent in color tone, resistances to pinhole, heat, and impact, and moldability such as film-forming properties. CONSTITUTION:This modified polyester is produced from an acid component comprising 80-95mol% arom. dicarboxylic acid and 5-20mol% dimerized fatty acid having an iodine value of 20g/100g or lower and a glycol component mainly comprising ethylene glycol and has a glass transition point of lower than 55 deg.C and a melt viscosity MV (P) at 280 deg.C satisfying the relation: 500<=MV<=4,000. |
