摘要： The problem to be solved by the present invention is to provide an effect pigment dispersion that exhibits excellent water resistance, that can form metallic or pearly luster, and that further exhibits high stability; and to provide a method for forming a multilayer coating film. The present invention provides an effect pigment dispersion that contains water, a wetting agent (A), a flake-effect pigment (B), and a phosphate-group-containing cellulose-based rheology control agent (C). The effect pigment dispersion has a solids content of 0.1 to 10 parts by mass, per 100 parts by mass of all of the components of the effect pigment dispersion; and has a viscosity of 100 to 10000 mPa·sec as measured with a Brookfield viscometer at a rotational speed of 6 revolutions per minute.
