Abstract

1282246 Solvent dyeing FARBENFABRIKEN BAYER AG 29 Oct 1970 [30 Oct 1969] 51511/70 Heading D1B [Also in Division C4] Synthetic fibres, e.g. polyamides, polyesters, cellulose triacetate, polyolefins and polyurethanes are dyed by an organic solvent dyeing process preferably in solvents immiscible with water having a B.P. of 40-150‹C e.g. tetra- or tri-chloroethylene, 1, 1, 1-trichloro-ethane and 1, 1, 1-trichloropropane by impregnating with a dye-liquor containing a dye of formula I: in which A is a radical of an ionic group-free optionally substituted benzene or naphthalene diazo component, R 1 is a C 1 -C 4 alkyl, C 1 -C 18 alkoxy-carbonyl or carbonamido group optionally substituted by C 1 -C 8 alkyl groups, R 2 is a C 1 -C 12 alkyl radical or optionally substituted aralkyl or aryl radical which is either directly linked or linked via a grouping of formula -CH 2 CH 2 OCO-, -CH 2 CH 2 OCOO- or -CH 2 CH 2 OCONH-, to the pyrazolone radical, with the proviso that the sum of carbon atoms in R 1 R 2 and the substituents of A is at least 6 and at most 36, R 2 and R 1 being free of ionic groups, the fibre then being subjected to a heat treatment e.g. dry heat at 120- 230‹C or in superheated solvent vapour at 100 to 150‹C.
