|20110021675||DISPERSING AGENT, AND PIGMENT COMPOSITION, PIGMENT-DISPERSED PRODUCT AND INKJET INK PREPARED THEREFROM - A dispersing agent characterized in that said dispersing agent is prepared by reacting primary and/or secondary amino groups of an amine compound comprising a polyamine (C) with isocyanate groups of a urethane prepolymer (E) having two isocyanate groups in one terminal region, wherein said urethane prepolymer (E) has been prepared by reacting hydroxyl groups in a vinyl polymer (A) having two hydroxyl groups in one terminal region with isocyanate groups in diisocyanates (B), and in that an amine number of said dispersing agent is 1 to 100 mgKOH/g is disclosed. The dispersing agent of the present invention has excellent dispersibility, flowability, and storage stability when used in small quantities. A pigment-dispersed product can be prepared therefrom, independently of the kinds of binder resin or solvent used. Further, the present invention is suitable for offset ink, gravure ink, resist ink for a color filter, inkjet ink, coating composition, and colored resin composition.||01-27-2011|
|20090250109||ACRYLIC PRESSURE SENSITIVE ADHESIVE COMPOSITION, DOUBLE COATED ADHESIVE SHEET, AND PHOTOVOLTAIC DEVICE - An acrylic pressure sensitive adhesive composition comprising (A) an acrylic polymer having a carboxyl group and (B) a tetrafunctional epoxy compound, without a substantial amount of a tackifying resin, wherein the acrylic polymer (A) has been prepared by copolymerizing (a) 50% to 80% by weight of butyl acrylate, (b) 5% to 40% by weight of ethyl acrylate, and (c) 7% to 22% by weight of at least one carboxyl group-containing compound selected from the group consisting of acrylic acid, methacrylic acid, itaconic acid, crotonic acid, monobutyl maleate and β-carboxyethyl acrylate; and which has a weight-average molecular weight (Mw) of about 600000 to about 800000 and a glass transition temperature of −35° C. to −10° C., is disclosed. Further, a double-coated adhesive sheet comprising the acrylic pressure sensitive adhesive composition, and a photovoltaic device fabricated, using the double-coated adhesive sheet, is disclosed.||10-08-2009|
