  • Patent number: 12234395
    Abstract: The present invention provides a pressure-sensitive adhesive composition, including: an acrylic copolymer and a crosslinking agent. The acrylic copolymer is a reaction product of a mixture of the following monomers: a first alkyl (meth)acrylate, an alkyl group in the first alkyl (meth)acrylate having at least 6 carbon atoms; a second alkyl (meth)acrylate, an alkyl group in the second alkyl (meth)acrylate having 1 to 5 carbon atoms; and a vinyl carboxylic acid, the weight ratio of the vinyl carboxylic acid to the mixture being 4% to 5%. The crosslinking agent is an organometallic chelating agent. The weight ratio of the organometallic chelating agent to the mixture is 0.05% to 0.25%. The pressure-sensitive adhesive composition does not contain an effective amount of a tackifier. The present invention further provides a pressure-sensitive adhesive solution, a pressure-sensitive adhesive tape, and a method for preparing the same.

  • Publication number: 20230348763
    Abstract: The present invention provides a UV-curable semi-structural adhesive, and a UV-curable semi-structural adhesive tape. The UV-curable semi-structural adhesive comprises: 30-80 parts by weight of a polymer base material comprising a product prepared by polymerization of an (meth)acrylate composition; 20-70 parts by weight of an epoxy resin; and a photoacid generator, wherein the (meth)acrylate composition comprises: 40-65 parts by weight of a first (meth)acrylate monomer containing a secondary hydroxyl group; 35-60 parts by weight of a second (meth)acrylate monomer; and a free-radical polymerization photoinitiator. The (meth)acrylate composition does not gel when used in the package-sealed UV polymerization process for producing semi-structural adhesives, and have good compatiility with epoxy composition, enabling the production of semi-structural adhesives through a solvent-free process.

  • Publication number: 20190010368
    Abstract: The present invention relates to a pressure-sensitive adhesive composition comprising an acrylate copolymer having a side carboxyl that is formed by a first monomer mixture containing a carboxyl-containing monomer, wherein, the content of the carboxyl-containing monomer is 0.1-10 wt. % based on the total weight of the first monomer mixture for forming the acrylate copolymer having the side carboxyl, the glass transition temperature Tg of the acrylate copolymer having the side carboxyl is larger than or equal to ?55° C. and less than or equal to ?30° C. The pressure-sensitive adhesive composition further comprises 1-25 wt. % of an acrylate oligomer with a weight-average molecular weight greater than or equal to 20,000 Da and a glass transition temperature Tg greater than or equal to 25° C., and 1-20 wt. % of a terpene tackifying resin based on the total weight of the acrylate copolymer having the side carboxyl and the acrylate oligomer.

  • Publication number: 20080158246
    Abstract: A method and system are provided for managing digital color for a display device having a display screen. Aspects the exemplary embodiments include receiving input display data comprising digital pixel data, wherein the data for each pixel represents 2D differential color space having X, Y coordinate values; remapping at least a portion of the coordinate values of the input display data locally in coordinates of the differential color space by reading from a memory of the display device color correction data that is configured to correct color errors of the display screen, wherein the color correction data is also represented in the differential color space, but the color correction data is only stored for a subset of X, Y coordinate values comprising the differential color space; interpolating the correction data read from the memory to generate remapped display data; and outputting the remapped display data for subsequent display.
