Abstract: An optical lens comprising a polyvinylalcohol film layer that is covalently bonded to a bulk polymerizable material during formation of the polymeric lens. The bulk optical lens polymer is preferably a glycol bis(allylcarbonate). Covalent bonding between these materials is achieved via an adhesive mixture that contains (a) a polyurethane to bond with the polyvinylalcohol layer, and (b) a polymethacrylate terpolymer with (i) pendant hydroxy groups that bind to the urethane, and (ii) pendant allyl groups that covalently bond to the bulk polymer. This strong covalent bonding reduces the chance of delamination of the lens during surfacing, polishing, and edging, and preserves its integrity during the lifetime of the finished eyewear.

Abstract: The present invention relates to an aqueous laminating adhesive composition and a method of using thereof. More particularly, the invention relates to an aqueous laminating adhesive composition comprising at least one aqueous polyurethane polymer dispersion (A), at least one aqueous non-polyurethane polymer dispersion (B) prepared by free radical polymerization, and at least one water dispersible polyfunctional crosslinking agent (C). Improved bonded properties of dry laminated flexible film substrates such as polyolefin, polyester and polyamide, as well as cellophane, metals or paper are obtained.

Abstract: A laminated structure (1) has a heat sealant layer (2), an antistatic layer (3) of a bisammonium organic sulfur semiconductor formed on one surface of the heat sealant layer (2). An oriented resin layer (14) is formed on the other surface of the heat sealant layer (2). The laminated structure (1) is adhered to a container with a side thereof on the side of the antistatic layer (3) to the container.

Abstract: A coating is provided for a substrate comprising a polyisocyanate; an amine donor and/or hydroxyl donor; an isocyanatosilane adduct having terminal isocyanate groups and at least one hydrolyzable alkoxy group bonded to silicon; and optionally a polymer selected from the group consisting of polyethylene oxide, polyvinyl pyrrolidone, polyvinyl alcohol, polyethylene glycol, and polyacrylic acid. The coating can accommodate a drug so that when the coating is applied to a medical device, the medical device becomes drug-releasing when in contact with aqueous body fluid. A coated article as well as a method for preparing the coating is also provided.

Abstract: An ink-fouling preventing sheet which is attached to a feed or delivery cylinder that supports and moves a printed paper in an offset press. The sheet comprises a flexible sheet base; an adhesive layer formed on the base; many small balls partially buried in the adhesive layer; a primer layer applied over the exposed convex portions of the small balls in the adhesive layer; and a set resin layer made of a silicone-modified urethane resin and applied on the primer layer to take the convex shapes of the small balls.

Abstract: Provided herein are novel polymeric coating materials for direct digital imaging by laser. More specifically the novel coating materials are thermally reactive near infrared absorption polymers designed for use with near infrared laser imaging devices. This invention further extends to the preparation and methods of use of the novel materials. The invention is particularly useful in the preparation of lithographic printing plates for computer-to-plate and digital-offset-press technologies. The invention extends to photoresist applications, to rapid prototyping of printed circuit boards and to chemical sensor development.
