Abstract: Provided is a method for producing an inorganic oxide in the form of a thin film, the method including a step of bringing a first liquid and a second liquid with each other, the first liquid containing an inorganic oxide precursor and the second liquid containing a substance reacting with the inorganic oxide precursor of the first liquid to form an inorganic oxide derived from the inorganic oxide precursor. The step is performed by continuous operation. At least one of the first liquid and the second liquid includes an ionic liquid.

Abstract: The present invention relates to [1] a process for producing a pigment composition, including the step of subjecting a raw material pigment composition containing C.I. Pigment Yellow 74, a specific by-product and water to heat treatment at a temperature of from 160 to 210° C.; and [2] a method of reducing a content of a by-product in a raw material pigment composition containing C.I. Pigment Yellow 74, the specific by-product and water, said method including the step of subjecting the raw material pigment composition to heat treatment at a temperature of from 160 to 210° C.
