Excerpt from Science, Vol. 15: A Weekly Journal Devoted to the Advancement of Science; January-June, 1902
From 1858 to 1886 may be called the 'rosanilin period' of the color industry, since it was chiefly marked by the develop. Ment of the colors of this group. A few individual members of other groups had been discovered, but had not attained im portance. This is especially true of the 'azo' dyes, which have attained such im portance that the last fifteen years may justly be called the 'azo period.' The number of individual compounds belonging to this class which have either been pre pared or are at present preparable, runs into many millions, and far exceeds the members of all other groups of coloring matters put together. In commercial im. Portance, also, they occupy a position at present far in advance of any other group; the employment of some of them, as the azo blacks, amounting to many thousands of tons annually. A great stimulus to the investigation of the azo compounds was given by the discovery by Boettger in 1884 of the first color possessing a direct afiinity for cotton (congo red), which was followed in a few years by a rapidly increasing series of colors of all shades having similar dyeing properties. The great simplification of cotton dyeing, brought about by the introduction of the new group of azo colors - 'benzo' or 'diamin' colors as they are called - led to a rapid increase of their number. Simultaneously therewith pro ceeded the discovery and investigation of the various isomeric derivatives of naphtha lene, required as raw products for the prep aration of these colors.
