Abstract

1,211,478. Dying aromatic polyesters and triacetyl cellulose. FARBWERKE HOECHST A.G. 6 May, 1968 [5 May, 1967], No. 21280/ 68. Additionto 1,103,028. Heading D1B. Water-insoluble azo dyes are produced on aromatic polyester or triacetyl cellulose by applying a preparation consisting of a) an arylamide of 2,3-hydroxynaphthoic acid or a derivative thereof, b) 4-amino-1-benzene-azonaphthalene or a derivative thereof, c) a watersoluble condensation product of an aromatic hydroxy compound and an aromatic #-methane-sulphonic acid, and d) water, and thereafter diazotising and coupling in situ. To avoid freezing lower (C2-4), aliphatic polyalcohols may be added, and fungicides, e.g. sodium penta-chlorophenolate are optional additives, anti-foaming agents may also be added, the preparations being obtained by grinding or kneading the components together.
