摘要： This invention provides a vinyl alcohol polymer-containing coating agent for paper, which, despite the fact that a curing step after coating the coating agent onto a paper surface can be omitted, can form a layer (for example, a coating layer or a color developing layer) having excellent water resistance and having no significant susceptibility to yellowing with the elapse of time. The coating agent is an aqueous composition comprising a vinyl alcohol polymer (A) satisfying a formula ";X + 0.2Y > 95", wherein X represents the content of vinyl alcohol units, % by mole; and Y represents the content of ethylene units, % by mole, and an addition condensation product (B) between ethylene urea and glyoxal. In the addition condensation product (B), the content of the terminal aldehyde group per g of the solid is 1.2 to 3.0 (mmol). The weight ratio on a solid basis between the vinyl alcohol polymer (A) and the addition condensation product (B) is in the range of (A) : (B) = 99 : 1 to 50 : 50. In the above formula, X
