摘要

1518996 Anionic dye granulates CIBAGEIGY AG 3 July 1975 [4 July 1974] 28120/75 Heading D1B Non-caking, non-dusty readily water soluble granules of anionic dyes (e.g. acid and reactive dyes) which granules contain 1 to 80 per cent by weight of anionic dye, 20 to 99 per cent by weight of at least one water-soluble organic melt carrier of MP 35 to 200‹C and optionally 1 to 10 percent by weight of further additives are obtained by dissolving the dye optionally with the additives in a melt of the organic compound followed by solidifying, and flaking, pelleting, spray drying or casting into moulds. Alternatively an organic solvent may be employed and this is removed after dissolving the dye in the melt.
