Disclosed are novel triazolylazo-N-alkyl(cycloalkyl)acylacetamide dye compounds which are colorless in solution but develop a yellow color when treated with ionic nickel such as nickel salts of organic acids or cobalt salts. This property is useful in conventional dyeing procedures and in reprographic processes wherein the dye compound is in hydrocarbon media when development of the color occurs.
本发明涉及新颖的三唑基偶氮-N-烷基(环烷基)酰乙酰胺
染料化合物,这些化合物在溶液中是无色的,但当与离子
镍(如有机酸
镍盐或
钴盐)处理时,会变成黄色。这种性质在传统
染料工艺和再现工艺中非常有用,其中
染料化合物在烃介质中时发生颜色变化。
