摘要：An object of the present invention is to provide a new acetoacetic ester group-containing polyvinyl alcohol-based resin that contains less amount of water-insoluble

matter and is excellent in transparency and viscosity stability when converted into anaqueous solution, and that realizes excellent water resistance by combined use of acrosslinking agent. The invention provides an acetoacetic ester group-containingpolyvinyl alcohol-based resin containing a structural unit represented by the generalformula (1): wherein at least one of R1 and R2 represents an acetoacetyl group, R3, R4,R5, R6, R7 and R8 each independently represents an arbitrary substituent, and Xrepresents a single bond or an arbitrary bonding chain.
