Abstract
A vinyl alcohol polymer is provided that is particularly useful for efficiently producing an inkjet recording material having an ink-receiving layer which is not cracked on its surface, which is highly glossy, which can absorb ink well and which is highly transparent, wherein the vinyl alcohol polymer has specific polyoxyalkylene group-containing monomer units and where the product of the viscosity-average degree of polymerization, P, of the vinyl alcohol polymer and the content, S (mol %), of polyoxyalkylene group-containing monomer units, P×S, and the number, n, of the oxyalkylene repeating units in the polyoxyalkylene group-containing monomer unit satisfy specific relational formulae.
