Abstract
Process for obtaining reactive dyes, characterized in that the organic dyes, which at least possess an exchangeable hydrogen atom or the organic compounds, have at least one interchangeable hydrogen atom and also at least their substituent for the formation of dyes, they are reacted with at least one molecule of a derivative of a 2,4,6-trihalo-pyrimidyl-5-alkyl, -alkyloaryl-, arylalkyl- or arylocarbonic or sulphonic acid derivative, and the products of reaction obtained, if they contain traces of organic compounds with substituents that enable them to form dyes, are transformed, by appropriate reaction, into the corresponding dyes.
