Abstract

A crosslinked polymeric composition of hydrolyzed poly(2-alkyl-2-oxazoline) is particularly useful for making high print quality color ink-jet films which are substantially water resistant.

Claims (15)

1 . A crosslinked polymeric composition of hydrolyzed poly(2-alkyl-2-oxazoline).

2 . A composition according to claim 1 wherein poly(2-alkyl-2-oxazoline) is partially hydrolyzed in an amount of about 1-75%.

3 . A composition according to claim 2 wherein said amount is about 5-40%.

4 . A composition according to claim 1 which is about 1-50% crosslinked.

5 . A composition according to claim 1 which is a crosslinked hydrolyzed product of poly(2-ethyl-2-oxazoline).

6 . A composition according to claim 1 which is a crosslinked random copolymer composed of the hydrolyzed unit of ethyleneimine and an unhydrolyzed unit of N-propronyl ethyleneimine.

7 . A composition of claim 1 wherein the crosslinking agent is a polyaziridine, a polyepoxide, a melamine/formaldehyde, a polycarboxylic acid, ammonium zirconium carbonate, or a polyaldehyde.

8 . A composition according to claim 1 in admixture with a film-forming polymer.

9 . A composition of claim 7 wherein said film-forming polymer is polyvinyl alcohol, polyvinyl pyrrolidone, gelatin, polyurethane, latex or cellulose.

10 . A color printable substrate according to claim 1 having the composition of claim 1 coated thereon.

11 . A method of making the composition of claim 1 which comprises hydrolyzing poly(2-alkyl-2-oxazoline) and crosslinking the hydrolyzed product.

12 . A method according to claim 11 wherein the hydrolyzing step is carried out in acid or base.

13 . A method according to claim 12 wherein crosslinking is effected by coating the hydrolyzed product onto a substrate and optionally heating.

14 . A composition of claim 1 which is in the form of an aqueous solution or hydrogel.

15 . A composition of claim 1 which is substantially free of propionic acid.
