Abstract:
(DE) Mit der Erfindung werden Alkandiole von 4 bis 8 C-Atomen als Entstaubungsmittel in festen Farbstoffpräparationen eingesetzt. Farbstoffpräparationen (-pulver), die solche Alkandiole enthalten, zeigen ein äußerst geringes Staubverhalten.
(EN) According to the invention, alkane diols of 4 to 8 C atoms are used as dust eliminating agents in solid dye preparations. Dye preparations (powders) containing such alkane diols give off extremely small quantities of dust.
