Abstract: In nanoimprinting processes, photo-cured products often separate from the substrate and stick to the mold due to insufficient adhesion between the photo-cured product and the substrate. This causes a defect of pattern separation. An adhesion layer composition used for forming an adhesion layer between a substrate and a photocurable composition includes a compound (A) having at least two functional groups, and a solvent (B). The functional groups include at least one functional group capable of being bound to the substrate, selected from the group consisting of hydroxy, carboxy, thiol, amino, epoxy, and (blocked) isocyanate, and at least one hydrogen donating group as a functional group capable of being bound to the photocurable composition.

Abstract: An adhesive tape is provided comprising a duct tape having an adhesive surface and a non-adhesive surface, a white ink printed on the non-adhesive surface of the duct tape, and a colored ink printed on top of the printed white ink. The white ink and the colored ink are digitally printed and UV curable. A self-wound roll of adhesive duct tape having digitally printed ink on the non-adhesive surface of the duct tape is also provided.

Abstract: An apparatus to be affixed to a vehicle to conceal a damaged portion of the vehicle where the apparatus has an exterior surface with a color base coat of paint covered with a clear coat finish, which color base coat of paint exactly matches the color base coat of paint on the vehicle and the clear covering serves to further match the color of the paint on the vehicle which in turn has a clear coat covering. The invention serves to conceal minor damage to the vehicle until the damage such as a ding, dent, scratch etc can be repaired.

Abstract: A transparent coating is used on an optical information disk. The optical information disk is an injection-molded piece of clear poly-carbonate plastic and is impressed with microscopic bumps which are arranged as a single, continuous, extremely long spiral track of data. A thin, reflective aluminum layer is sputtered onto the optical information disc so that the thin, reflective aluminum layer covers the bumps. A thin acrylic layer is sprayed over the thin, reflective aluminum layer in order to protect it. The transparent coating is a composite material which is made of silica as the discontinuous phase and of a polytetrafluoro-ethylene-derived organic polymer as the continuous phase which leads to a fluorine-containing silica-based product. The transparent coating is applied by spin or dip from specific solutions at room temperature followed by a mild and short heat treatment.

Abstract: An optical information medium comprises a supporting substrate, an information recording surface 4 on the supporting substrate and a light-transmitting layer of resin on the information recording surface. Recording light and/or reproducing light are incident on the information recording surface through the light-transmitting layer. The light-transmitting layer is obtained by curing a resin layer containing an ultraviolet-curing cationic resin. If the light-transmitting layer is formed by repeating the cycle of resin coating and curing or drying a plurality of times, the uniformity of thickness of the light-transmitting layer can be much more improved and the amount of warpage can be much more reduced. Repetition of the cycle of resin coating and curing or drying is also effective for resins other than the ultraviolet-curing cationic resin.

Abstract: A phase change optical recording medium has on a substrate a recording layer consisting essentially of a Sb base thin film and a reactive thin film. The Sb base thin film is formed by depositing a Sb base material containing at least 95 at % of Sb to a thickness of 70-150 Å. The reactive thin film is formed of a material which forms a phase change recording material when mixed with Sb. The reactive thin film is typically formed of an In—Ag—Te or Ge—Te material. Stable write/read characteristics are accomplished at the first overwriting, initializing operation is eliminated, and rewriting is impossible at the same linear velocity as recording.
