Abstract: Provided is a conductive material dispersion liquid for a lithium-ion secondary battery positive electrode, containing a conductive material, methyl octyl cellulose, and a dispersion medium.

Abstract: The present invention relates to a recording liquid comprising at least: a pigment (a); and a polymer (b) having one or more types of bond selected from the group consisting of amide bond, urethane bond and urea bond in the molecule, having a weight-average molecular weight of 5000 to 300000 and having an acid value of free acid of not less than 55 mgKOH/g and less than 150 mgKOH/g, the surface tension of said recording liquid being 25 to 54 dyne/cm.

Abstract: Disclosed are a printing plate precursor, a fabrication process of the printing plate precursor, a fabrication process of a printing plate, a regeneration process of the printing plate, a printing press, and a coating formulation for the printing plate precursor. According to the present invention, a printing plate can be fabricated directly from digital data, and sufficient image quality can be obtained without a developing step, i.e., a developer. To permit repeated use of the precursor, the precursor has a surface, which contains a photocatalyst and is capable of showing hydrophilicity when exposed to activating light having energy higher than band gap energy of the photocatalyst.
