Abstract: Compounds of the general formula R(O-CO-NH-CH2-A-X)n, where R stands for an organic residue preferably aliphatic, A is the group of atoms which forms an aliphatic or heterocyclic tertiary amine, X stands for the anion of an acid, and n is a whole number greater than 1, are made by treating the compound R(OH)n with phosgene and treating the chloroformic ester so obtained with ammonia, whereby a polycarbamate R(OCONH2)n is obtained.  This is treated with formaldehyde and a halogenating agent such as hydrochloric acid, phosgene, thionyl chloride or phosphorus pentachloride, or alternatively with dihalogenodimethyl ether. The halogenomethyl compound formed is then reacted with an aliphatic or heterocyclic tertiary amine.  The compound R(OH)n may be obtained from hydrogenated castor oil or castor oil; e.g. 11-hydroxystearic-N,N-di-(b -hydroxyethy)-amide may be made from hydrogenated castor oil, and octadecane-1,12-diol may be made from completely hydrogenated castor oil.  The compound R(OH)n may also be the diester from ethylene glycol and terephthalic acid.ALSO:Textile materials are dyed or printed with inorganic or organic pigments which are applied in the presence of a compound of the general formula R(O.CO.NH.CH2.A.X)n, where R stands for an organic residue, preferably aliphatic, A is the group of atoms which forms an aliphatic or heterocyclic tertiary amine, X stands for the anion of an acid, and n is a whole number greater than 1.  The coloured material may be subjected to a heat treatment, e.g. at 100 DEG  to 150 DEG  C.  When used for printing, the compounds may be included in a printing paste of the water-in-lacquer or lacquer-in-water type, and there may be present synthetic resins or synthetic resin components, many of which are specified, as well as drying oils, natural and synthetic rubbers, latex and plasticizers. In example (1), a cotton fabric, viscose or cellulose acetate artificial silk, is printed with a paste containing the dyestuff 3,31-dichlorobenzidine \sQ 1-phenyl-3-methyl-5-pyrazolone, tristearin - tris - (carbamatomethylpyridinium) trichloride, gum tragacanth and sodium acetate, dried and steamed or baked at 150 DEG  C. Alternative compounds of the above general formula are triolein - tris - (carbamatomethylpyridinium) trichloride, stearic - N,N - diethylamido - 11,b ,b 1-tri - (carbamatomethylpyridinium) trichloride, tristearin - tris - (carbamatomethyltrimethyl - ammonium) trichloride, tristearin - tris - (carbamatomethyltrimethylammonium) - triacetate, octadecylene - 1,12 - bis - (carbamatomethylpyridinium) dichloride, ethyl - 1,2 - bis - (carbamatomethylpyridinium) dichloride, terephthalyl - bis - (oxyethylenecarbamatomethylpyridinium) dichloride and trimethylene-1,3-bis-(carbamatomethylpyridinium) dichloride.  In other examples, (2) cotton fabric is printed with an emulsion containing the dyestuff 2,5-dichloroaniline --> 2,3 - hydroxynaphthoic - p - toluidide, solvent naphtha, ethyl cellulose, tristearin - tris - (carbamatomethylpyridinium) trichloride, morpholine and polyvinyl chloride and then steamed; (3) cotton fabric is printed with an emulsion containing copper phthalocyanine pigment, solvent naphtha, ethyl cellulose, linseed, dehydrated-castor oil-modified alkyd resin, tristearin-tris-(carbamatomethylpyridinium) trichloride and morpholine, and dried at 105 DEG  or baked at 150 DEG C.; (4) cotton fabric is printed with an emulsion containing dimethyl ether of dimethylolurea, gum tragacanth, tristearin - tris - (carbamatomethyltrimethylammonium) trichloride, n - propanol, chalk, solvent naphtha and the dyestuff 3,31-dichlorobenzidine \sQ 1 - phenyl-3-methyl-5-pyrazolone, and baked at 150 DEG  C.; (5) cotton fabric is printed with an emulsion containing chlorinated copper phthalocyanine pigment, chalk, tristearin - tris - (carbamatomethyltrimethylammonium) trichloride, n-propanol, gum tragacanth, tung-linseed oil-modified alkyd resin, xylene and solvent naphtha, and then baked at 150 DEG  C.; (6) cotton is printed with an emulsion containing carbon black, solvent naphtha, chalk, tristerrin - tris - (carbamatomethyltrimethylammonium) trichloride, n-propanol, dibutyl phthalate, ethyl cellulose and hexamethoxy - methyl - melamine, and then baked at 150 DEG  C.; (7) cotton is printed with an emulsion containing ethyl cellulose, solvent naphtha, the pigment p-chloro-o-nitroaniline --> acetoacet-o-chloro-anilide, dimethylolurea dimethyl ether, morpholine and tristearin-tris-(carbamatomethylpyridinium) trichloride, and then dried at 105 DEG  or baked at 150 DEG  C.; (8) cotton is printed with an emulsion containing ethyl cellulose, solvent naphtha, titanium dioxide, terephthalyl - bis - (oxyethylene - carbamatomethylpyridinium) dichloride, iso - propanol, dibutyl phthalate, chalk and polyvinyl chloride, and then dried at 105 DEG or baked at 150 DEG  C.; and (9) cotton is printed with an emulsion containing xylene, tung-linseed oil-modified alkyd resin, solvent naphtha, ethyl cellulose, the pigment 2,5-dichloroaniline --> 2,3 - hydroxynaphthoic - p - toluidide, ethanol, tristearin - tris - (carbamatomethyltrimethylammonium) triacetate and chalk, and then dried at 105 DEG  or baked at 150 DEG  C.
