    摘要： A method for determining coat weight of a printed transparent electrophotographic composition is described, in which a calibration composition is added to a transparent liquid electrophotographic composition to produce a test composition, the calibration composition comprising a carrier liquid, a polymer resin, and at least 5 wt. % of an optical brightening agent based on the total solids content of the calibration composition. The test composition is electrophotographically printed onto a test substrate to produce the printed transparent electrophotographic ink composition; the fluorescence of the printed transparent electrophotographic composition is measured; and the coat weight of the printed transparent electrophotographic composition is determine based on the fluorescence of the printed transparent electrophotographic composition.

    摘要： Described herein is a two-component coating system. The two-component coating system may include a base component and a hardener component. The base component may include: up to 55 wt. % hydroxyl terminated polyester and/or hydroxyl terminated polyether; up to 3 wt. % hydroxyl terminated polysiloxane; and a solvent selected from aromatic hydrocarbons, ketones, esters and combinations thereof, wherein the hydroxyl terminated polyester and/or hydroxyl terminated polyether and the hydroxyl terminated polysiloxane are dissolved in the solvent. The hardener component may include: up to 80 wt. % polyisocyanate; and a solvent selected from aromatic hydrocarbons, ketones, esters and combinations thereof, wherein the polyisocyanate is dissolved in the solvent.

    摘要： Herein is disclosed a method of electrostatic printing and glossing comprising: forming a first toner image on a print substrate by electrostatically printing an electrostatic ink comprising a first resin component comprising an ethylene acrylic acid resin, an ethylene methacrylic acid resin or combinations thereof; forming a second toner image disposed on the first toner image on the print substrate by electrostatically printing a liquid electro photographic (LEP) printing composition comprising a first resin component comprising an ethylene acrylic acid resin, an ethylene methacrylic acid resin or combinations thereof, and a second resin component present in an amount of about 20% to about 80% by weight of total solids content of the LEP printing composition, the second resin component having a melting point of from about 50° C. to about 75° C., which is below the melting point of the first resin component, or from about 140° C. to about 180° C., which is above the melting point of the first resin component; heating the print substrate to at least partially melt the first or second toner image.
