Provided is a conductive carbon mixture which is to be used together with an electrode active material in manufacturing an electrode of an electricity storage device and enables the manufacture of the electricity storage device having a good cycle life. The conductive carbon mixture for manufacturing an electrode of an electricity storage device comprises an oxidized carbon having electrical conductivity and a different conductive carbon which is different from the oxidized carbon, wherein the oxidized carbon covers the surface of the different conductive carbon. The conductive carbon mixture is characterized in that the ratio of the peak intensity of the 2D band to the peak intensity of the D band in a Raman spectrum of the conductive carbon mixture is 55% or less relative to the ratio of the peak intensity of the 2D band to the peak intensity of the D band in a Raman spectrum of the different conductive carbon. This conductive carbon mixture covers the surface of the electrode active material in a particularly good manner and thus prolongs the cycle life of the electricity storage device.

The present invention relates to a pigment water dispersion containing a pigment, a crosslinked polymer and water, in which the crosslinked polymer is prepared by crosslinking a carboxy group-containing polymer with a crosslinking agent, and has an acid value of not less than 70 mgKOH/g and not more than 300 mgKOH/g; and the pigment water dispersion further contains a formaldehyde-releasing compound. The pigment water dispersion of the present invention is excellent in storage stability even when being stored under high-temperature conditions for a long period of time.
