Zusammenfassung:	It is intended to provide a novel polyvinyl alcohol resin which is excellent in viscosity stability of an aqueous solution, high speed coatability, reactivity with a cross-linking agent and water solubility. The invention relates to the polyvinyl alcohol resin containing a structural unit having as a side chain a carboxyl group-containing long-chain alkyl group represented by the general formula (1). (1) (In the formula, R1 and R2 independently represent a hydrogen atom or an alkyl group, R4, R5 and R6 independently represent a hydrogen atom or an alkyl group, R3 represents a hydrogen atom, an alkyl group or an alkali metal and n represent a positive integer.) L'invention concerne une nouvelle résine d'alcool polyvinylique qui est excellente en ce qui concerne la stabilité de la viscosité d'une solution aqueuse, l'aptitude à l'application en revêtement à haute vitesse, la réactivité avec un agent de réticulation et la solubilité dans l'eau. L'invention concerne la résine d'alcool polyvinylique contenant une unité structurale ayant, comme chaîne latérale, un groupe alkyle à longue chaîne contenant un groupe carboxyle, représenté par la formule générale (1). (1) (Dans la formule, R1 et R2 représentent indépendamment un atome d'hydrogène ou un groupe alkyle, R4, R5 et R6 représentent indépendamment un atome d'hydrogène ou un groupe alkyle, R3 représente un atome d'hydrogène, un groupe alkyle ou un métal alcalin et n représente un entier positif).
