Abstract
A cellulose polymer network crosslinked with metal ions selected from the group consisting of: Al.sup.+3, Zr.sup.+4, and Ti.sup.+4, the crosslinked cellulose polymer network having incorporated therein a colloidal sol containing metal oxide-hydroxide particles wherein the metal is Al, Zr, or Ti. The inventive material is optically clear and can be used to cast microporous films, either supported or unsupported, which are useful as coatings on ink jet recording materials.
