| 摘要 |
Specific novel compounds of aromatic bis-acetoamide structures are provided as intermediate compounds to forming different types of coloring agents, at least. Such compounds are useful as intermediates in the production of certain bis-acetoanilide azo dyes, pigments, and polymeric colorants. Such compounds facilitate production of such coloring agents that exhibit favorable tinctorial strength and intense color from orange to greenish yellow within and on different substrates and media. Coloring agents and methods of making such agents are encompassed within this invention as well.
