    Abstract: Provided is a Michael addition product prepared from a multifunctional acryl monomer having multiple hydroxyl groups allowing introduction of acryl functional groups, as a Michael acceptor, and a Michael donor. The Michael addition product is a novel multifunctional compound having an oligomer and a photoinitiator moiety in the molecule. Since it can be cured under a standard UV curing condition without having to add a photoinitiator, it is reduced to air pollution or health problem. Therefore the superior physical properties were obtained by cured coatings without surface tackiness. In addition, its hydroxyl groups allow, through isocyanate bonding or introduction of acryl groups, 3-dimensional crosslinking and molecular and compositional design for improving expandability, friction, and reactivity and hydrophilicity for self-adhesion, hardness of cured film, or the like. Consequently, a very useful, multifunctional or water-dispersible coating composition may be prepared.

The solvent-free photocurable resin composition contains a urethane(meth)acrylate oligomer, a trifunctional (meth)acrylic acid ester monomer, a photopolymerization initiator, and a dilution monomer. The dilution monomer contains a fluorine-based (meth)acrylic acid ester monomer having three or more fluorine atoms and a monofunctional or difunctional (meth)acrylic acid ester monomer in amounts of from 10 to 40 wt% and from 10 to 30 wt%, respectively.

  • Publication number: 20120065350
    Abstract: The present invention provides a resin material which can be used for a pressure-sensitive adhesive sheet for protecting a semiconductor wafer and the like, does not cause curve (warpage) in the semiconductor wafer when the semiconductor wafer is ground, is excellent in followability to a pattern, has adequate stress dispersibility in a grinding operation, suppresses the crack in a wafer and chipping in a wafer edge, and does not leave a residue of a tackiness agent on the surface of the wafer in a peeling operation. The resin material shall be a viscoelastic body containing a copolymer of a urethane polymer and an acrylic polymer, which is formed through a monomer having a functional group that can form a urethane bond with a urethane polymer and having an activated carbon double bond that can copolymerize with a (meth)acryloyl group, in one molecule.

  • Patent number: 8128990
    Abstract: The invention provides a coating composition for an optical element, such as an ophthalmic lens. The coating composition includes a relatively rigid multifunctional monomer and a relatively flexible difunctional monomer. The rigid multifunctional monomer and the flexible difunctional monomer are capable of co-reacting to form an abrasion resistant coating on the optical element. The invention also provides a method of forming an abrasion resistant coating on an optical element, such as an ophthalmic lens. The method includes the steps of coating the optical element with a relatively rigid multifunctional monomer and a relatively flexible difunctional monomer, and polymerising the coating to form an abrasion resistant coating on the optical element.

  • Publication number: 20120046412
    Abstract: Non water-soluble polymers with a comb structure and a (meth)acrylic skeleton on which are grafted side chains containing at least one hydrophobic monomer of the styrene or (meth)acrylic ester type on C1 to C4, and at least one hydroxy or methoxy polylakylene glycol monomer. The levels of monomers are such that the polymer is amphiphilic because it is both rich in hydrophobic monomer and polylakylene glycol monomer. These products, used in paper coating dispersions, enable an increase in their Brookfield™ viscosity, a reduction in their ACAV viscosity, and an improvement in their water retention, which makes them particularly well suited for dry extract and/or high deposit speed coatings.

  • Publication number: 20120016050
    Abstract: Urethane acrylate oligomers, suitable for use in coatings and like formulations, prepared by capping polyols having hydroxyl functionality (fOH) equal to or greater than 4, using 2-isocyanatoethyl acrylate or 2-isocyanatoethyl methacrylate, thereby avoiding the gelation that normally occurs in attempting to prepare urethane acrylates with high/OH polyols by reaction with diisocyanates. Reaction of low molecular weight polyols, containing two or three hydroxyl groups, with mono isocyanate(meth)acrylate monomers produces useful, low viscosity urethane (meth)acrylate oligomers. Specifically, capping of a mole of 2,2-dihydroxymethyl butanoic acid by two moles of 2-isocyanatoethyl acrylate molecules leads to the formation of radiation curable water-soluble liquid monomers that are transparent and soluble in water. Oligomers obtained by capping with 2-isocyanatoethyl acrylate demonstrate enhanced adhesion to glass and stainless steel.
