Abstract
Provided is a near infrared absorbing fine particle dispersion liquid, which can be applied to a base material such as an acrylic resin base material having a low solvent resistance, including: a solvent of one or more kinds selected from petroleum-based solvents; near infrared absorbing fine particles of one or more kinds selected from 10 mass % more and 25 mass % or less of a composite tungsten oxide expressed by MxWyOz, and/or a magneli phase expressed by the general formula WyOz; and a dispersant having a fatty acid in its structure and soluble in the solvent, wherein a viscosity is 180 mPa/S or less.
