  • Patent number: 10370573
    Abstract: An object of the present invention is to provide a thermal conductivity-giving material capable of giving substantially the same level of a thermal conductivity as that of the conventional material by using a smaller amount thereof than that conventionally used or giving a higher thermal conductivity than that of the conventional material by using substantially the same amount thereof as that conventionally used. The aforementioned problem can be solved by an easily deformable aggregate (D) comprising 100 pts·mass of thermally conductive particles (A) having an average primary particle diameter of 0.1 to 10 ?m, and 0.1 to 30 pts·mass of an organic binding agent (B), in which the easily deformable aggregate (D) has an average particle diameter of 2 to 100 ?m, and an average compressive force required for a 10% compressive deformation rate is 5 mN or lower.

  • 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.
