<p>PROBLEM TO BE SOLVED: To provide a hot melt adhesive composition using an aliphatic polyester that is excellent in application workability, fitness for instantaneous adhesion, and initial-stage adhesion characteristics, and that is suitable for bonding papers and biodegradable plastics. SOLUTION: The resin composition comprises an aliphatic polyester component (A) obtained by polycondensation of at least an aliphatic dicarboxylic acid, an anhydride thereof, or a diester thereof (a), 20-70% in molar ratio per (a) of an aliphatic dicarboxylic acid having an alkyl or alkenyl group in the side chain, an anhydride thereof, or a diester thereof (b), and an aliphatic glycol (c), and an aliphatic polyester component (B) obtained by polycondensation of at least an aliphatic dicarboxylic acid, an anhydride thereof, or a diester thereof (a), and an aliphatic glycol (c).</p> |
