| titleOfInvention | Quinophthalone compound |
| abstract | A novel quinophthalone compound is here disclosed which is represented by the formula (1)n n [wherein when R₁ is an alkyl group having 8 or less carbon atoms which may branch, or cycloalkyl group, R₂ is a hydrogen atom, halogen atom, alkoxy group which may be substituted, alkylthio group, arylthio group which may be substituted, each of R₃ and R₄ is a hydrogen atom, alkyl group, N-substituted aminocarbonyl group, or substituted or unsubstituted heterocyclic ring having two or more atom of one or more kinds selected from the group consisting of a nitrogen atom, oxygen atom and sulfur atom, and R₃ and R₄ may be bonded to each other to form a ring; nhowever, when R₁ is a hydrogen atom, each of R₃ and R₄ is a hydrogen atom, or substituted or unsubstituted heterocyclic ring having two or more atoms of one or more kinds selected from the group consisting of a nitrogen atom, oxygen atom and sulfur atom]. n The above-mentioned compound is useful for coloring of polymeric materials, liquid crystal materials and the like. |
