ABSTRACT:
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.
