Provided is a vinyl alcohol polymer useful for producing an inkjet recording material having an ink collection layer having no surface cracks, high gloss, excellent ink absorption, and high transparency.n n n The vinyl alcohol polymer of the present invention contains a specific polyoxyalkylene group-containing monomer unit, and has a viscosity average degree of polymerization (P) and a polyoxyalkylene group-containing monomer unit content (S) (mol%) relative to all monomer units in the polymer. The number of oxyalkylene repeating units (n) in the product (PxS) and the polyoxyalkylene group-containing monomer unit is a vinyl alcohol polymer that satisfies a specific relationship. |
