Abstract
PURPOSE: To prevent solidification and decomposition of a diazonium salt type azoic dye, by adding a specified builder to said dye.
CONSTITUTION: To a diazonium salt type azoic dye such as 3-chlorobenzenediazonium chloride is added, as a builder, metaboric acid in an amount of 1/2W2- fold mol of the moisture adhering to the dye or boric anhydride in an amount of 1/6W 2/3-fold mol of the moisture.
EFFECT: The dye has an excellent thermal stability. Lowering in the solubility and the titer of the dye can be prevented. Troubles such as tar formation during dyeing can also be prevented.
