Document Type and Number:
WIPO Patent Application WO/2020/059670
Kind Code:
A1
Abstract:
A pigment-containing resin composition which contains a pigment and a resin (A) and satisfies conditions 1-3. Condition 1: the resin (A) has an anionic group, and at least part of the anionic group of the resin (A') which contains a polyester structure is neutralized by a neutralizing agent (b). Condition 2: the volatile substance content in the pigment-containing resin composition is 1 mass% or less. Condition 3: the average particle diameter, when obtained according to the cumulant analysis method and measured by dynamic light scattering, in a water dispersion (α) obtained by dispersing the pigment-containing resin composition in water in a manner such that the concentration of the pigment-containing resin composition therein is 2×10-4 mass%, is 0.5μm or less.
