  • Publication number: 20120288972
    Abstract: The present invention provides an ink jet printable phosphor ink composition for LED packaging that enables precision control of the amount and position of phosphor layers on the LED device or the LED device packaging. The ink includes both a UV-curable resin component and a thermally curable resin component. A phase-separation component prevents phase separation of the UV-curable resin component and the thermally curable resin component. Phosphor particles on the order of less than approximately 2 microns are uniformly dispersed throughout the ink composition. The phosphor ink composition is deposited through either thermal or piezoelectric ink jet printing; a thin layer is deposited in a desired pattern. UV curing (and, optionally, thermal curing) is used to fix each layer followed by subsequent deposition and curing. In this manner, undesirable phosphor settling does not occur and layers are selectively built up to form precise phosphor distributions.

  • Patent number: 8178198
    Abstract: An adhesive sheet includes a substrate and an energy-ray curable adhesive layer formed on the substrate. The energy-ray curable adhesive layer includes an energy-ray curable acrylic copolymer and a urethane acrylate. The energy-ray curable acrylic copolymer is formed by copolymerizing at least one of either a dialkyl(meth)acrylamide that has an alkyl group with carbon number of not more than 4, a phenol EO modified (meth)acrylate that has an ethylene glycol chain with a phenyl group bonded to the ethylene glycol chain, a (meth)acryloyl morpholine, or a (meth)acrylate that has an aceto-acetoxyl group, in total of 1 to 30 weight percent of all monomers to form the energy-ray curable acrylic copolymer. The energy-ray curable acrylic copolymer further includes a side chain with an unsaturated group.

  • Patent number: 8168689
    Abstract: A high optical contrast pigment and colorful photosensitive composition employing the same are disclosed. The composition comprises a solvent, an alkali-soluble resin, reactive monomer, and a modified pigment which has low crystallization. The low crystallization degree means that the grain size variation R is not more 80%, wherein the grain size variation R is represented by a formula R=G1/G0×100%, G0 is the original grain size, and G1 is the grain size after modification.

  • Patent number: 8158726
    Abstract: The present invention provides poly(thioesters) and monomeric diesters, produced from di(hydroxyethyl)polysulfides and various mono- and di-basic carbonic acids or their anhydrides, and their derivatives. The new compounds combine properties of polyesters and polysulfides. The poly(thioesters) can be used as components in many compositions, including but not limited to adhesives, sealants, caulks, coatings, plastics, paints and elastomers. The monomeric diesters find use in compositions such as solvents and plasticizers.
