PROBLEM TO BE SOLVED: To obtain a resin composition for paper coating, which does no emit produced occurring generate formaldehyde and provides coated paper with improved water resistance. SOLUTION: The resin composition for paper coating is a resin composition obtained by reacting five or six components of (A) a polyamine, (B) (B-1) an aliphatic dibasic carboxylic acid and/or (B-2) a reaction product containing a free carboxy group at the molecular end prepared by reacting 1 mol in number of mols of a glycol with >1 mol in number of mols of an aliphatic carboxylic acid, (C) a urea, (D) a crosslinkable compound and (E) a lactam. The amount of (D) the crosslinkable compound is≥0.001 mol and≤0.25 mol based on 1 mol in number of mols of (A) the polyamine. COPYRIGHT: (C)2008,JPO&INPIT
