Abstract
Polyethylene terephthalates, superpolyamides or polyolefines are coloured in the melt, prior to spinning or moulding, by incorporating therewith, prior to melting, a 1:9-pyrazole-anthrone dyestuff which is free from water-solubilizing groups. Incorporation of the dyestuff may be effected by mechanical mixing of the polymer in powder, granule or chip from with the finely divided dyestuff. In the case of polyamides, the dyestuff may be incorporated before or during the polycondensation of the monomers. Suitable dyestuffs are those of the formula:- <FORM:0889000/IV (a)/1> in which R represents an alkyl group, those of the formula:- <FORM:0889000/IV (a)/2> and those of the formulae:- <FORM:0889000/IV (a)/3> in which R1 and R2 represent hydrogen atoms or alkyl, cycloalkyl or aralkyl residues. Examples describe the colouring of polymer chips which are then melt-spun into filaments or moulded into articles.
