  • Publication number: 20120141180
    Abstract: Treatments are described for surfaces of substrates to improve adhesion with a phase change ink. A method of forming an image on a coated substrate with a phase change ink includes treating a surface of the coated substrate with a corona discharge treatment, a plasma treatment and/or an electron-beam treatment prior to image formation, and subsequently forming an image on the surface of the treated coated substrate with a phase change ink, wherein the image formed on the substrate has an LV Index that is reduced compared to that of an image formed on the untreated substrate. A phase change ink printing apparatus includes a corona discharge, plasma and/or electron-beam treatment device; and a phase change ink printing device, wherein the corona discharge, plasma and/or electron-beam treatment device is located upstream, in a process direction, from the phase change ink printing device.

  • Patent number: 7906581
    Abstract: Methods, apparatuses, and systems for manufacturing a hot melt adhesive containing an adhesion promoter in a continuous mode include supplying a melted, hot melt adhesive to a mixing device at a first predetermined rate while simultaneously supplying an adhesion promoter to the same mixing device at a second predetermined rate to form a homogeneous admixture containing the hot melt adhesive and adhesion promoter. The hot melt adhesive/adhesion promoter mixture is subsequently reacted in at least one tubular reactor at a predetermined temperature for a predetermined residence time to allow the adhesion promoter to chemically bond with the hot melt adhesive and form an adhesive-promoter-treated hot melt adhesive. The adhesion-promoter-treated hot melt adhesive is collected in a product receiver and may be further processed.

  • Publication number: 20100196682
    Abstract: A surface treatment method of oil contaminated xerographic prints which increases the surface energy of the print to levels close to the values corresponding to the original uncontaminated paper. Subjecting the contaminated surface to both ultraviolet (UV) radiation and ozone can change the chemical structure of the surface of the paper in such a way that a highly polar surface is created as a consequence of this treatment, leading to enhanced adhesion properties of the xerographic print.

  • Publication number: 20100196819
    Abstract: Provided herein is a surface treatment method of oil contaminated xerographic prints which increases the adhesion of the print to levels close to the values corresponding to the original uncontaminated paper. Subjecting the contaminated surface to corona treatment alone and in combination with ultraviolet (UV) radiation and ozone can change the chemical structure of the surface of the paper in such a way that a highly polar surface is created as a consequence of this treatment, leading to enhanced adhesion properties of the xerographic print.

  • Patent number: 7754812
    Abstract: An adhesion promoter for a hot melt adhesive or a pressure sensitive adhesive prepared by admixing a hydrolytic silane compound with an aqueous buffer solution. The adhesive is able to bind at very low surface free energy substrates, such as Xerographic prints contaminated by silicone fuser oil. The hot melt adhesive maintains a substantially stable viscosity at temperature ranging from about 100° C. to about 200° C.

  • Publication number: 20090184157
    Abstract: Exemplary embodiments provide a pressure-seal cohesive and method for making and using the pressure-seal cohesive to form mailer type business forms. The disclosed pressure-seal cohesive can provide an improved cohesive sealing of the mailer forms. In particular, the pressure-seal cohesive can include at least one silane promoter admixed with at least one aqueous pressure sensitive compound formulation that contains pressure sensitive cohesive and/or adhesive compounds. The admixed silane promoter can have a concentration ranging from about 0.5% to about 2.5% weight percent of the pressure-seal cohesive to improve the compatibility of the pressure sensitive compounds, even if they are contaminated by the fuser oils (e.g., functionalized PDMS oil) during digital printing processes (e.g., on Xerox iGen3).
