Abstract

An inkjet ink container is disclosed comprising a polymer compound comprising an oxygen scavenging composition. The oxygen scavenging composition is selected from the group consisting of copolymers of polycondensate segments and oxygen scavenging moiety segments; oxygen scavenging unsaturated polymers; oxygen scavenging dendrimers; molecular hydrogen generators; and combinations thereof.

Claims (17)

1. An inkjet ink container comprising a polymer compound comprising an oxygen scavenging composition,

wherein the oxygen scavenging composition is selected from the group consisting of:

(a) copolymers of polycondensate segments and oxygen scavenging moiety segments;

(b) oxygen scavenging unsaturated polymers;

(c) oxygen scavenging dendrimers;

(d) molecular hydrogen generators; and

(e) combinations thereof.

2. The container of claim 1 , wherein the polymer compound comprises a thermoplastic resin selected from the group consisting of polyesters, polyamides, polyolefins, polycarbonates, polystyrenes, polyacrylates, thermoplastic elastomers of all types, and combinations thereof.

3. The container of claim 2 , wherein the polyester comprises polyethylene terephthalate, polybutylene terephthalate, polylactides or polyhydroxyalkanoates.

4. The container of claim 1 , wherein the inkjet container is a print cartridge body.

5. The container of claim 1 , wherein the inkjet container is an ink supply container for connection with a print cartridge body.

6. The container of claim 1 , wherein the container is an ink supply container of any size or shape in which inkjet ink is stored before association with an inkjet printer.

7. The container of claim 6 , wherein the container is an ink supply container of ink in bulk.

8. The container of claim 1 , wherein the oxygen scavenging composition scavenges for

(a) oxygen molecules within the volume of the container not occupied by the ink,

(b) oxygen molecules within walls of the container, and

(c) oxygen molecules permeating through the container walls.
