Patent ID: 7297382

Claim:
An ink jet recording material comprising a support and at least one ink receiving layer containing a water-soluble or water-dispersible polymer, wherein said polymer comprises a repeating monomeric unit having a moiety capable of chelating boric acid by means of at least one nitrogen containing functional group and at least one hydroxyl group thereby forming a five- or six-membered ring and wherein said repeating monomeric unit is represented by formula (II): wherein, R 1 is selected from the group consisting of a substituted saturated aliphatic group, an unsubstituted saturated aliphatic group, a substituted unsaturated aliphatic group, a substituted or unsubstituted aryl group, and a substituted or unsubstituted heteroaryl group; R 2 is selected from the group consisting of hydrogen, a substituted or unsubstituted, saturated or unsaturated aliphatic group, a substituted or unsubstituted aryl group, and a substituted or unsubstituted heteroaryl group; L 2 represents a linking group containing two or three carbon atoms which may be further substituted or may be part of a ring; any of L 2 , R 1 and R 2 may combine to form a ring, and at least one of L 2 , R 1 and R 2 comprises an ethylenically unsaturated polymerizable group.
