White ink composition, ink set for forming multiple layers, image forming method and printed matter

摘要

The invention provides a white ink composition for inkjet recording, including: titanium dioxide having an average primary particle diameter of from 200 nm to 350 nm; a hydrophilic, layered clay mineral; a water-soluble resin; and water. The invention further provides: an ink set for multilayer formation including the white ink composition and an ink composition for inkjet recording, including a colorant having a hue other than white; an image forming method including applying the white ink composition to a recording medium and irradiating the white ink composition applied to the recording medium with an active energy ray; and a printed matter including an image formed on a recording medium by the image forming method.
