Patent number: 7745505Abstract: UV-crosslinkable acrylic hotmelt pressure sensitive adhesives comprising acrylic and vinyl monomers, and a polymerizable UV photoinitiator. The photoinitiator comprises a spacer comprising both ethylene oxide and urethane, or urea, carbonate, or siloxane functional groups. The ethylene oxide is directly bonded to the chromophore (e.g., benzophenone) moiety, while the urethane (or urea, carbonate, siloxane) is closely linked to the polymerizable moiety (e.g., styrenic C?C double bond).Type: GrantFiled: December 29, 2004Date of Patent: June 29, 2010Assignee: Henkel AG & Co. KGaAInventors: Yuxia Liu, Darwin Scott Bull

Patent number: 7732505Abstract: An active energy ray-curable ink composition comprising a colorant, a monomer and a photopolymerization initiator, in which the monomer contains an acrylamide derivative in an amount of 10 to 90% by weight based on the whole weight of the ink composition, and the ink composition has a viscosity of 3 to 35 mPa·s at 25° C. The ink composition has a low viscosity without dilution by a diluent solvent, good storage stability, good pigment dispersibility when a pigment is used as a colorant and also good continuous ejection stability to a printing medium, has a good curing property at a low energy level such as a cumulative amount of light of 150 mJ/cm2 or less, and it can attain good printing quality on nonabsorbable printing medium and achieves good adhesion of printed images to the printing medium.Type: GrantFiled: October 6, 2005Date of Patent: June 8, 2010Assignee: Hitachi Maxell, Ltd.Inventors: Katsuyuki Kito, Nagayuki Takao

Publication number: 20100129550Abstract: Pigments for inkjet inks are controllably functionalised to improve water-dispersibility, ozone resistance, etc., by irradiation of the pigment particle with high energy radiation, such as gamma radiation in air or by plasma activation, to form a stable functionalisable intermediate pigment particle, then activating the stable functionalisable intermediate, e.g. by heating, in the presence of a functionalising precursor (e.g. a polymer or polymerisable monomer) to form a modified pigment particle having one or more functionalising group grafted onto the pigment particle.Type: ApplicationFiled: December 22, 2005Publication date: May 27, 2010Inventors: John D. Goddard, Alan R. Pitt, Elizabeth A. Simister, Mark Bradley, Anais F. Ronot

Publication number: 20100098887Abstract: Disclosed is an optical recording medium which can increase the gloss of a print receptive layer provided on a level surface and can provide a high quality print. An optical recording medium (200) comprises a record-reproducing layer (10) which is a substrate-incident medium and a print receptive layer (20) which can be printed with an ink and is provided on the surface opposite to the surface of the record-reproducing layer (10) which receives the irradiation with light. The print receptive layer (20) comprises a filler-containing layer (22) which contains a hydrophilic resin and an organic or inorganic filler as main ingredients and a non-filler-containing layer (21) which is laminated on the filler-containing layer (22) and contains no organic or inorganic filler.Type: ApplicationFiled: August 2, 2006Publication date: April 22, 2010Applicant: Mitsubishi Kagaku Media Co., Ltd.Inventors: Fujio Matsuishi, Kouichirou Haraguchi
