Document Type and Number:
WIPO Patent Application WO/2007/122706
Kind Code:
A1
Abstract:
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
