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

Abstract: A process for preparing terylene-3,4:11,12-tetracarboximides I where the variables are each defined as follows: R, R' are each independently hydrogen; if desired substituted alkyl or cycloalkyl; R 1 is hydrogen or alkyl; R 2 is hydrogen; alkyl; if desired substituted aryl or hetaryl, by reacting a perylene-3,4-dicarboximide II in the presence of a base-stable, high-boiling organic solvent and of an alkali metal or alkaline earth metal base, with a naphthalene-1,8-dicarboximide III in which X is hydrogen, bromine or chlorine.

Abstract: Composite pigments (CP) based on (A) nano-particulate metal oxides modified with optionally crosslinked polyalkylene- polyamine (PAPA) and (B) anionic dyes. Also claimed is (i) a process for the production of CP, (ii) metal oxide nano-particles modified as above (A), and (iii) a process for production of (A).
