Claims19
A method of enhancing adhesion of an image to at least one surface of a substrate where the image was from an electrophotographic printer utilizing liquid toner technology and the image was based on a liquid toner, the method, comprising treating at least a portion of a substrate prior to printing with a composition comprising a water soluble or water dispersible binder and a water soluble or water dispersible binder additive, wherein the binder additive comprises a polymer comprising one or more repeat units, wherein the one or more repeat units has a localized strong, negatively charged dipole and no strongly positively charged dipole.
A method of enhancing adhesion of a liquid toner based image to at least one surface of a substrate, comprising:
- (a) surface treating at least a portion of at least one surface of a substrate with a composition comprising a binder and a binder additive to form a print receiving coating on at least a portion of the at least one surface of the substrate;
- and
- (b) liquid electrophotographic printing an image on at least a portion of the print receiving coating using a liquid toner;
- wherein the binder additive comprises a polymer comprising one or more repeat units, wherein the one or more repeat units has a localized strong, negatively charged dipole and no strongly positively charged dipole.
A printed material, comprising:
- (a) a treated substrate comprising a substrate treated with a composition comprising a binder and a binder additive to form a treated substrate, and
- (b) an image on at least a portion of one surface of the treated substrate, wherein the image is printed on the treated substrate using a liquid electrophotographic printer and a liquid toner;
- wherein the binder additive comprises a polymer comprising one or more repeat units, wherein the one or more repeat units has a localized strong, negatively charged dipole and no strongly positively charged dipole.
