Abstract: PROBLEM TO BE SOLVED: To obtain a complex pigment capable of exhibiting good application characteristics by including a specific polyalkylee polyamine-modified nano particulate metal oxide and an anion dye. SOLUTION: This complex pigment comprises (A) nano particulate metal oxide modified with a crosslinked or uncrosslinked polyalkylenepolyamine and (B) an anion dye. The nano particulate metal oxide of the component A includes preferably silicon dioxide. The complex pigment is obtained by adjusting an aqueous suspension of the component A to pH 3-6 and heating the aqueous suspension to
