Abstract
A method of enhancing adhesion of an image to at least one surface of a substrate is provided herein. The method includes treating at least a portion of the surface by applying a composition comprising one or more polymers to the portion of the surface. The method further includes drying the composition after applying the composition to the substrate to form a treated substrate. The method further includes printing an image from an electrophotographic printer utilizing liquid toner technology on the treated substrate. The substrate is treated and dried less than about 5 minutes prior to being printed.
Claims20
A method of enhancing adhesion of an image to at least one surface of a substrate, the method comprising:
- treating at least a portion of the surface by applying a composition comprising one or more water soluble polymers to the portion of the surface, wherein each of the one or more polymers comprises a repeat unit, and wherein the repeat unit comprises a negatively charged dipole moment of greater than 2 debyes, and wherein the repeat unit comprises no positively charged dipole moment of greater than 0.8 debyes;
- drying the composition after applying the composition to the substrate to form a treated substrate;
- and
- printing an image from an electrophotographic printer utilizing liquid toner technology on the treated substrate;
- wherein the composition is free of a polymer of ethylene and acrylic acid and a polymer of ethylene and methacrylic acid;
- and
- wherein the composition is free of a binder.
A printed material, comprising:
- a surface treated substrate comprising a print receiving coating, wherein the print receiving coating is coated on at least a portion of at least one side of the substrate, wherein the print receiving coating comprises one or more water soluble polymers, wherein the one or more polymers comprises one or more repeat units have a negatively charged dipole of greater than 2 debyes, and have no positively charged dipole of greater than 0.8 debyes;
- and
- an image on at least a portion of the print receiving coating, wherein the image is printed on the print receiving coating from an electrophotographic printer utilizing liquid toner technology;
- wherein the composition is free of a polymer of ethylene and acrylic acid and a polymer of ethylene and methacrylic acid;
- and
- wherein the composition is free of a binder.
A method of enhancing adhesion of an image to at least one surface of a substrate, the method comprising:
- treating at least a portion of the surface by applying a composition comprising one or more water soluble homopolymers to the portion of the surface, wherein each of the one or more water soluble homopolymers is formed from 2-ethyl-2-oxazoline or methyloxazoline and has a weight average molecular weight of from about 500,000 to about 2,000,000 Daltons;
- drying the composition after applying the composition to the substrate to form a treated substrate;
- and
- printing an image from an electrophotographic printer utilizing liquid toner technology on the treated substrate;
- wherein the composition is free of a polymer of ethylene and acrylic acid and a polymer of ethylene and methacrylic acid;
- and
- wherein the composition is free of a binder.
