Abstrakt:
The paper is focused on innovation of a chemical process leading to new amino
compounds of structural formula I and their application to preparation of new azo
dyes II. The procedure of preparation of the key derivative is presented. This
derivative is aminonaphthoxazoledisulfonic acid III, which is used in syntheses of
a number of azo dyes belonging to various technological and application
categories. In this way, a chemically new class of azo dyes, containing the
naphtho[2,1-d]oxazole skeleton in their molecules, was established.
