    Abstract: Ethers of highly polymeric formaldehyde are obtained by reacting the latter with an alphachoralkyl ether of an aliphatic, cycloaliphatic, heterocyclic or aromatic hydroxyl compound, preferably in the presence of a basic compound, or with a quaternary salt of the alpha-chloralkyl ether with a tertiary amine. Alpha-chloralkyl ethers mentioned are chlormethyl methyl ether, chlormethyl ethyl ether, bis-(chlormethyl) ethylene glycol ether, bis-(chlormethyl) butane-diol-(1,4) ether, chlormethyl cyclohexyl ether, chlormethyl benzyl ether and chlormethyl cyclohexyl ether. In Examples polyformaldehyde is reacted with quaternary salts of dimethylcyclohexylamine with chlormethyl methyl ether, 1,4-bis (chlormethoxy) butane, alpha-chlorethyl isobutyl ether, alpha-chlorethyl benzyl ether and 2,3-dichlordioxane.

    Abstract: The invention comprises any ammonium salt derived from a 1 : 1 chromium complex of an azo or azomethine dye which contains a sulphonic acid group and a primary, secondary or tertiary amine whose nitrogen atom is substituted by an aliphatic radical containing at least one ether oxygen atom and which aliphatic radical may in turn have aromatic substitution. Among the amines specified for use in the process are 1-methoxy-3-aminopropane, 1 - benzyloxy - 2 - dimethylaminoethane, N - methylmorpholine and 1 - (b - ethyl - hexoxy) - 3 - aminopropane. Among processes described in examples are those in which the 1 : -chromium complex of the azo dye 6 - nitro - 2 - hydroxy - 1 - amino - naphthalene - 4 - sulphonic acid --> 2 - hydroxynaphthalene is boiled with 1-(b -ethyl-hexoxy)-3-aminopropane in aqueous ethanol; 4-nitro-2-aminophenol - 6 - sulphonic acid --> 1 - phenyl-3 - methyl pyrazolone - (5) is reacted with 1 - (b - ethyl - hexoxy) - 3 - aminopropane in aqueous formic acid and 4-nitro-2-aminophenol - 6 - sulphonic acid in aqueous solution is reacted with 2-hydroxy-5-nitrobenz-aldehyde; the product is boiled with aqueous chromium chloride and the product is reacted with 1 - (b - ethylhexoxy) - 3 - amino propane in aqueous acetic acid solution.

    Abstract: The invention comprises an ammonium salt of a 1 : 2 cobalt or 1 : 2 chromium complex of an azo dye and/or an azo methine dye and a primary, secondary or tertiary aliphatic amine whose nitrogen atom is substituted by an aliphatic radical which contains at least one ether oxygen atom. The ammonium salts are prepared by reacting appropriate complexes and amines. Representative of the many amines specified are 1-methoxy-3-aminopropane, 1 - benzyloxy - 2 - dimethylaminoethane, 1-(b -acetoxyethoxy) - 2 - diisopropylaminoethane and N-methylmorpholine. The metal complex dyes may be free from sulphonic acid groups or bear 1 to 4 such groups. Representative of the many azo dyes specified are 1-amino-2-hydroxy-4 - nitrobenzene --> 3 - methyl - 1 - phenylpyrazolone, 2-aminobenzoic acid --> 1-phenyl-3-methylpyrazolone, 1 - amino - 2 - hydroxybenzene - 4 - sulphamide --> 2 - hydroxynaphthalene, 1 - amino - 2 - hydroxybenzene - 5-sulphonethylamide --> acetoacetanilide and of the azomethine dyes those obtained from 4-nitro - 2 - aminophenol and 3,5 - dichlor - 2 -hydroxybenzaldehyde or 2-hydroxynaphthaldehyde. The products are soluble in organic solvents and or suitable for colouring nitrocellulose lacquers, anodized aluminium, cellulose ethers, polyester and polyamide resins and ester- and ketone-soluble vinyl chloride polymers. Examples are furnished.
