(57) [Summary] [PROBLEMS] To be able to be manufactured by conventional manufacturing equipment and to have a long pot life, excellent work survivors, and dry it at a comparatively low temperature even if a crosslinking agent coexists in its aqueous solution. The present invention also provides a polyvinyl alcohol-based resin composition exhibiting excellent water resistance and a paper coating agent using the same. SOLUTION: (A) Diacetone acrylamide copolymer modified polyvinyl alcohol containing 0.1 to 15 mol% of diacetone acrylamide units, (B) a water-soluble hydrazine compound and (C) a water-soluble organic amine or ammonia are blended. And a paper coating agent containing the same as a main component. |
