More Information
Summary:An object of the present invention is to provide a dioxazine pigment having excellent fluidity. More specifically, an object of the present invention is to provide a dioxazine pigment in which practically sufficient fluidity is attained in both (1) initial viscosity and (2) storage stability when the dioxazine pigment is used in a printing ink application. The object is attained by providing a dioxazine pigment having a contact angle with respect to water according to an infiltration rate method in a range of 30° to 75°, and a contact angle with respect to 1-bromonaphthalene according to an infiltration rate method in a range of 30° to 75°.
