  • Optically clear adhesives for durable plastic bonding
    Patent number: 10214666
    Abstract: The present invention is a copolymer of a monomer mixture including about 25 to about 80 parts by mass of an alkyl (meth)acrylate, approximately 15 to approximately 50 parts by mass of a hydroxyl group-containing monomer, and approximately 5 to approximately 25 parts by mass of a macromer having a glass transition temperature (Tg) of approximately 50° C. or higher. The copolymer contains substantially no acidic groups.
    Type: Grant

  • OPTICALLY CLEAR ADHESIVE AND OPTICAL LAMINATE
    Publication number: 20170240782
    Abstract: Problem: To provide an optically clear adhesive with a high dielectric constant having an excellent balance of adhesive strength and cohesive strength as well as excellent optical characteristics, and an optical laminate containing the same. Solution: The optically clear adhesive of an embodiment of the present disclosure comprises a polymer of an acrylic monomer composition containing a hydroxyl group-containing monomer and at least 0.09 mass % and less than 50 mass % of a monofunctional alkyl (meth)acrylate, wherein the number of moles of OH in 100 g of the adhesive is at least 0.3 and at most 0.90.

  • Conductive trace hiding materials, articles, and methods
    Patent number: 9477354
    Abstract: An article includes a patterned substrate including a substrate surface with an inorganic electro-conductive trace adjacent thereto (wherein the substrate and the inorganic material of the trace each has an index of refraction), and a layer including a polymerized acrylate matrix adjacent to at least a portion of the surface of the substrate and the inorganic electro-conductive trace, wherein the layer has an index of refraction that is within ±10% of the average of the indices of refraction of the substrate and the inorganic material of the trace.
