Abstract

1,273,880. Melt-dyeing polyamides. CIBAGEIGY A.G. 25 June, 1970 [26 June, 1969], No. 30864/70. Heading C3R. Linear polyamides are dyed in the melt with an α,α<SP>1</SP>-anthrimidecarbazole containing an acylamino group in at most one position para to an -NH- group and which may contain further substituents. To the polyamide, in the form of powder, granules, or chips, the dyestuff may be added as a powder, e.g. it may be a powder obtained by heating a polyamide with a dispersion of the dyestuff in a water-soluble alcohol and then cooling the mixture. Or the dyestuff may be added to the polyamide during or immediately after polycondensation. Fibres or films may be formed. The polyamide may be polyamide 6/6, 6, or 11, or a corresponding mixed polyamide. The dyestuff may be where X = H or an acylamino gp., e.g. benzylamino. There may be 1 part by weight dyestuff per 99 parts polyamide.
