Carbamates

A process for the cross-linking or chain extension of hycrocarbon polymers which contain ethylenically unsaturated groups which comprises forming an intimate mixture of the polymer with a carbamate of the formula: ##STR1## WHEREIN R.sub.1 is an optionally substituted hydrocarbyl radical, m is an integer, and A is H or an optionally substituted hydrocarbyl radical of valency m, and subjecting the mixture to heat. Novel compounds of preferred use include those in which m=1 and at least one of R and A is alkyl or 7 or more carbon atoms, or in which m=2 and A is phenylene or alkylene or alkenylene of 2 to 4 carbon atoms.

Process of crosslinking unsaturated hydrocarbon polymers employing novel

A process for the transfer color printing of synthetic textile materials wherein the dyestuff used is a 1-amino-4-anilinoanthraquinone having one or two ortho substituents in the anilino group. The anthraquinone nucleus may be further substituted in the 2- and/or 3-position, preferably by an electron-withdrawing group in the 2-position.

Transfer dyeing with 1-amino-4-anilinoanthraquinone dyes

A process for the cross-linking or chain-extension of hydrocarbon polymers which contain ethylenically unsaturated groups which comprises forming an intimate mixture of the polymer with a mono-sulphonyloxycarbamate of the formula:

Cross-linking hydrocarbon unsaturated polymer with

Poly-carbonyloxyurethanes

Poly-sulphonyloxyurethanes of the formula

Nitrogen-containing compounds

Compounds of the formula ##STR1## WHEREIN A is a linking group, X is an O--CO-- or --SO.sub.2 -- group and n is at least 2, are prepared from the corresponding N',N'-disubstituted hydrazides by quaternization and treatment with alkali or reaction with an alkylene epoxide or from the corresponding compound wherein n = 1 and A is a polymerizable group by polymerization. The compounds are unstable to heat and may be used as cross-linking agents for polymers or as chain-extending agents, bonding agents or adhesives.

Oxyformamidates

Compounds of the formula A--X--N.sup.+--N.sup.-  .sub.n, wherein A is a linking group, X is an O--CO-- or --SO.sub.2 -- group and n is at least 2, are prepared from the corresponding N',N'-disubstituted hydrazides by quaternisation and treatment with alkali or reaction with an alkylene epoxide or from the corresponding compound wherein n = 1 and A is a polymerisable group by polymerisation. The compounds are unstable to heat and may be used as cross-linking agents for polymers or as chain-extending agents, bonding agents or adhesives.

A new class of cellulose reactive dyes have a sulphonated benzene, naphthalene or naphthalene azobenzene diazo component coupled on to a class of coupling components of the formula: ##SPC1## In which T.sup.1 is H, monocyclic aryl, OH, CO.sub.2 H, aminocarbonyl, lower alkyl, lower alkoxy and lower alkoxycarbonyl, T.sup.2 is H, CO.sub.2 H, lower alkyl, lower alkoxy, monocyclic aryl, benzyl, aminocarbonyl and lower alkoxycarbonyl, the diazo component carrying a cellulose-reactive group. Also included are dyes in which two moles of such a monoazo dye are linked through a diamine radical. Cr and Co complexes of dyes in which the diazo component is a o-aminophenol or o-aminonaphthol are included. These dyes are usefully employed to color cellulose, wool or polyamide textile materials. These dyes impart to the textile materials deep shades having excellent fastness to light and to the wet treatments which are commonly applied to cellulose textile materials.
