Abstract
A print medium for ink-jet printing comprises a photobase substrate, a porous ink-receiving layer and a subbing layer. The photobase substrate can include paper and a moisture barrier layer coated on at least one side of the paper. The porous ink-receiving layer can include metal oxide or semi-metal oxide particulates treated with an organosilane reagent and aluminum chlorohydrate, and a polyvinyl alcohol binder. The subbing layer can be disposed between the moisture barrier layer of the photobase and the ink-receiving layer and include a polyvinyl alcohol or a copolymer of a polyvinyl alcohol.

21. A method of preparing a print medium for ink jetprinting, comprising:
-
a) coating a subbing layer including polyvinyl alcohol or a copolymer of polyvinyl alcohol on a moisture barrier of a photobase substrate; b) treating metal oxide or semi-metal oxide particulates with an organosilane reagent and an aluminum complex to form treated particulates; and c) coating the treated particulates on the subbing layer using a binder of polyvinyl alcohol or copolymer of polyvinyl alcohol, thereby forming an ink-receiving layer. - View Dependent Claims (22, 23, 24, 25)
