Water resistant composition, coating agent, and recording material

摘要

Provided are a water resistant composition comprising a uniform mixture of (A) at least one of modified polyvinyl alcohol containing from 1 to 20 mol% of alpha -olefin units with not more than 4 carbon atoms, modified polyvinyl alcohol containing from 0.01 to 1 mol% of silyl groups, and modified polyvinyl alcohol containing from 1 to 20 mol% of alpha -olefin units with not more than 4 carbon atoms and from 0.01 to 1 mol% of silyl groups and (B) an organotitanium compound having a chelating ligand, wherein the blend ratio of the component (A) to the component (B), (A)/(B) falls between 99.99/0.01 and 60/40 by weight; a coating agent comprising the composition; a thermal recording material having a coat layer of the composition; and an ink-jet recording material having an ink-absorbing layer of the composition.
