Abstract
A print medium having increased resistance to gasfade. An inhibitor comprising a sulfur-containing polymer is incorporated into the print medium. The sulfur-containing polymer is poly(1,4-phenylene sulfide) or poly(1,3-phenylene sulfide). The inhibitor is present in at least a surface of the print medium and may be present in the print medium in a concentration from approximately 0.25% by weight per cm2 of the print medium to approximately 30% by weight per cm2 of the print medium. A method of forming the print medium is disclosed as is a method of producing a printed image having increased resistance to gasfade.
Claims16
A print medium having increased resistance to gasfade, comprising:
- a melt-coated, discrete, topmost inhibitor layer on at least one surface of the print medium, the layer including at least one odorless sulfur-containing polymer, wherein the at least one polymer has a molecular weight greater than approximately 1000, wherein the at least one polymer is selected from the group consisting of poly(1,4-phenylene sulfide), poly(1,3-phenylene sulfide), and combinations thereof, and wherein the print medium comprises a plain paper, a porous print medium, or a swellable print medium.
A print medium having increased resistance to gasfade, comprising:
- a melt-coated discrete inhibitor layer on at least one surface of the print medium, the layer including at least one poly(phenylene sulfide), wherein the at least one poly(phenylene sulfide) has a molecular weight greater than approximately 1000, and wherein the at least one poly(phenylene sulfide) is present at a concentration from approximately 0.25% by weight per cm2 of the print medium to approximately 30% by weight per cm2 of the print medium.
A method of forming a print medium having increased resistance to gasfade, comprising:
- providing a medium comprising a plain paper, a porous medium, or a swellable medium;
- melting an ozone inhibitor selected from at least one odorless sulfur-containing polymer, wherein the polymer has a molecular weight greater than approximately 1000, and wherein the polymer is selected from the group consisting of poly(1,4-phenylene sulfide), poly(1,3-phenylene sulfide), and combinations thereof;
- and
- applying the melted inhibitor as a topmost, discrete layer on at least one surface of the medium, thereby forming the print medium having increased resistance to gasfade.
A method of producing a printed image having increased resistance to gasfade, comprising:
- depositing inkjet ink onto a medium, the medium comprising a plain paper, a porous medium, or a swellable medium;
- melting an ozone inhibitor selected from at least one odorless sulfur-containing polymer, wherein the polymer has a molecular weight greater than approximately 1000, and wherein the polymer is selected from the group consisting of poly(1,4-phenylene sulfide), poly(1,3-phenylene sulfide, and combinations thereof;
- and
- applying the melted inhibitor as a topmost, discrete inhibitor layer onto at least one surface of the medium, thereby producing the printed image haying increased resistance to gasfade.
A print medium having increased resistance to gasfade, comprising:
- a melt-coated, topmost, discrete inhibitor layer on at least one surface of the print medium, including at least one odorless poly(phenylene sulfide);
- wherein the at least one poly(phenylene sulfide) has a melting point ranging from approximately 125° C. to approximately 400° C. and a glass transition temperature ranging from approximately 75° C. to approximately 250° C., and wherein the print medium comprises a plain paper, a porous print medium, or a swellable print medium.
A print medium having increased resistance to gasfade, comprising:
- a melt-coated topmost, discrete, inhibitor layer on at least one surface of the print medium, the layer including an at least one odorless sulfur-containing polymer;
- wherein the at least one polymer is present in a concentration from approximately 0.25% by weight per cm2 of the print medium to approximately 30% by weight per cm2 of the print medium;
- wherein the at least one polymer is selected from the group consisting of poly(1,4-phenylene sulfide), poly(1,3-phenylene sulfide), and combinations thereof;
- and wherein the print medium comprises a plain paper, a porous print medium, or a swellable print medium.
A print medium having increased resistance to gasfade, comprising:
- a melt-coated topmost, discrete inhibitor layer on at least one surface of the print medium, the layer including at least one odorless sulfur-containing polymer, the at least one polymer being selected from the group consisting of poly(1,4-phenylene sulfide), poly(1,3-phenylene sulfide), and combinations thereof.
