Abstract: An adhesive for an electrical storage device packaging material containing a polyol compound (A), a polyisocyanate compound (B), and an epoxy resin (C), in which the polyol compound (A) contains an ester bond-containing polyol, and the following formula is satisfied when a stress at the time when a cured film obtained by performing curing under the condition of 80° C. for 2 weeks is stretched to twice its length at a speed of 6 mm/min under an environment of 20° C. and 65% RH is S1 [N/mm2], and a stress at the time when the cured film is held for 100 seconds in a stretched state is S2 [N/mm2]. Formula: 10.0?(S1?S2)/S1×100?40.0.

Abstract: 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.

Abstract: A nonaqueous ink composition for an ink jet recording, comprising (A) a urethane resin dispersant with an acidic functional group, (B) a pigment, and (C) an organic solvent [and optionally (D) a thermal reactive compound], characterized in that the urethane resin dispersant (A) is a branched urethane resin dispersant prepared by polymerizing a terminal-isocyanate-containing compound (p), which has been prepared by reacting (a) a polyisocyanate having three or more isocyanate groups, and (b) a monoalcohol, under the condition that a molar ratio (Ma/Mb) of the number of moles (Ma) of isocyanate groups (NCO) from the polyisocyanate (a) to the number of moles (Mb) of hydroxyl groups (OH) from the monoalcohol (b) is 3/2 to 3/0.
