Abstract: The present invention provides new linear phosphorus- and halogen-containing flame retardant polyester additives for normally flammable polymers and coatings for normally flammable natural and synthetic films and fibers, for instance, polyester and cellulose ester films and fibers. The phosphorus- and halogen-containing polymers of the invention are water dispersible or can be rendered water-soluble. They can be prepared by reacting a phosphorus acid reactant such as phosphoric acid with at least one halogenated difunctional monomer. The water-soluble polyesters can be cross-linked to render them insoluble in water by heating together with a methylol compound.Said halogenated monomer is preferably an oxyalkylated diacid or diol and said halogen is attached either on one or more aromatic rings or on a cycloaliphatic ring.

Abstract: Monoazo and disazo dyes having an unsubstituted or substituted aniline or p-aminoazobenzene as diazo component and an N-substituted .beta.-naphthylamine of six to eighteen carbon atoms in the N-substituent as coupling component. Preferred diazo components are phenyl, tolyl, phenylazophenyl and tolylazotolyl, and preferred coupling components are provided by .beta.-naphthylamine which is N-monosubstituted by n-hexyl, n-octyl, .beta.-ethylhexyl, 3,5,5-trimethylhexyl, tridecyl, .beta.-ethylhexoxypropyl, cyclohexyl, benzyl or phenylethyl. The dyes are eminently suitable for the coloring of for example mineral oils, gasoline, fats and waxes because of their excellent solubilities.
