  • Patent number: 8344047
    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.

  • Publication number: 20060163499
    Abstract: An electron beam irradiation apparatus includes an electron beam emission section having an electron beam irradiating tube that emits an electron beam; an electron beam irradiation section for irradiating the emitted electron beam to a target; a transfer mechanism for transferring the target to the electron beam irradiation section; a rotation mechanism for rotating the target on its own axis when irradiating the electron beam; and a linear movement mechanism for generating a relative linear movement such that the electron beam irradiating tube passes right above the target, between the target and the electron beam irradiating tube, when irradiating the electron beam. The linear movement mechanism generates a relative linear movement such that the electron beam irradiating tube goes from an end portion of the target toward the center of the target and turns back before the center of the electron beam emitting portion of the electron beam irradiating tube reaches the center of the target.
