Abstract
The present invention provides a water-resistant surface coating formulation comprising a reaction product obtained by subjecting an acrylamide polymer to a crosslinking reaction with 0.1 to 20 parts by mole, per 100 parts by mole of amido groups in the acrylamide polymer, of a glyoxalmonoureine; a method for improving the water resistance of paper by using the formulation; and coated paper so obtained. As a result of improved water resistance of the coating formulation, this invention makes it possible to conduct coating work stably.
