摘要
An N-substituted benzamide-based azo yellow pigment is provided to ensure resistance to solvents, drug resistance and light-proof property, and to replace the regulated yellow pigment in the industry field including ink and paint. An N-substituted benzamide-based azo yellow pigment has a structure indicated as the chemical formula 1. In the chemical formula 1, X shows a bonding line or C1-C6 alkylene group; R^1 shows hydrogen atom, amide group, C1-C6 alkyl group or C1-C6 haloalkyl group; R^2 shows a hydrogen atom, C1-C6 alkyl group or C1-C6 alkyl group; R^3, R^4, R^5, R^6, and R^7 show respective hydrogen atom, halogen atom, C1-C6 alkyl group or C1-C6 alkyl group; or R^4 and R^5 can form a fused ring of benzimidazolone by being bonded with an adjacent group.
