A method for treating a plastic surface to facilitate the adhesion of a coating. Specifically, the plastic surface is cleaned to remove surface contaminants. The resulting clean surface is then treated by a surface treatment, to thereby produce a treated surface suitable for receiving a coating. In some embodiments, the plastic surface treatment facilitates the adhesion of ink used in UV inkjet printing on plastic surfaces, including surfaces that are textured or irregularly shaped. In one embodiment of the invention, the plastic surface is a surface of a high density polyethylene (HDPE) plastic seat that is used for telescopic seating.

The invention relates to compositions for forming two and three-dimensional artwork, pictures, works of design and architectural works that are interactive, responsive or able to change. These compositions can include at least one nanomaterial. They can include a light emitter that is one or a combination of: an OLED; a light-emitting display screen that is partially or entirely transparent or translucent; a light-emitting display screen capable of flexing or folding; or a thin light-emitting display screen. In different embodiments, the composition includes electronic paper; a visible tangible transparent or translucent form or display capable of aesthetic change; a visible interactive or responsive intangible hologram; or an organic transistor, a transparent transistor, an organic light-emitting transistor (OLET) or a transistor that is a combination of these; or a conductive polymer. Aesthetic works of the invention are created, developed, changed, reworked or recreated interactively, in a responsive process, repeatedly or continuously.

An ink composition for screen printing for a glass substrate includes a solvent with a boiling point at least 170° C. at least 70 mass % of the total solvent and a prepolymer or polymer with a weight-average molecular weight of at least 2000 at least at 2 mass % with respect to total ink composition, and with a viscosity of 5 to 180 Pa.Math.s measured with a BH-type rotating viscosimeter at 25° C. and thixotropic index (TI value) of 2.0 to 8.0, the measured flow radius value being 13.0 to 24.0 mm after 1 minute from start of measurement by a flow property measuring method using a spread meter at 25° C. according to JIS K5701-1:2000, satisfying “F60”−“F45”≦1.0 mm, where “F60” and “F45” are measured flow radius values after 1 minute and 45 seconds, respectively, from start of measurement, and containing a coupling agent compound.

A process including the steps of: providing a water soluble film; providing an ink including between about 5% and about 30% by weight a solvent selected from the group consisting of diols, cyclic polyols, diglycols, triols, polyols, and mixtures thereof; and applying the ink onto the water soluble film.

A laminate that possesses dye sublimation properties, particularly for use as tagless labels and embellishments for garments, apparel, fabric items and so forth such as sportswear fabrics, clothing and accessories is provided. The laminate includes a dye sublimation ink layer that overlies a substrate in which the dye sublimation ink interacts with the substrate's chemical make-up.

This invention is about a digital printing method of cover sheet of a flexible material of required features of density, flexibility and thickness. This method includes steps of printing a cover sheet of woven or non-woven fabric, by using digital or computerized printing techniques, either direct printing or by transfer paper printing or sublimation printing technique. The printed side of the cover sheet is laminated or coated with a clear film of flexible transparent material like polyurethane, thermoplastic polyurethane, polyethylene or polyvinylchloride. This laminated or sealed printed and coated cover sheet may be fixed to different fabric, foam or of outer surface layer of an article at which printing is required. The said article may be sport's good, sport's wears, dresses, footwear, furniture covering sheets and vehicle items covers etc. The novel method of making cover sheet enables customized printing at required articles at user request with many design printing possibilities. While use of water based ink for digital printing provides an environment friendly, efficient, and durable method of printing the cover sheets of these products.

An object of the present invention is to provide an active energy ray-curable lithographic ink that exhibits good adhesion to a plastic film and does not cause a decrease in the adhesion capability even during hot-water treatment. The present invention encompasses an active energy ray-curable lithographic ink containing (a) a polyurethane and (b) a polymerizable monomer.

An actinic radiation curable composition comprising a carboxylated acrylate, a urethane acrylate, a monomer, and a photoinitiator is disclosed herein, which both provides satisfactory adhesion to a substrate surface and may be effectively removed by caustic wash. Also provided is a method of printing, comprising applying an actinic radiation curable composition as disclosed herein onto a surface of a substrate, curing the applied composition, and applying an ink on the cured composition.
