A heat-sensitive recording material which comprises in its color reactant system, as developer for the color former, at least one aluminum or zinc phenate of a phenolsulfonyl compound of the formula ##STR1## wherein R is C.sub.1 -C.sub.12 alkyl, cycloalkyl, phenyl, benzyl, or phenyl which is substituted by halogen, lower alkyl, lower alkoxy, nitro or methylenedioxy, and

A heat-sensitive recording material which comprises in its color reactant system, as developer for the color former, at least one aluminum or zinc salt of a phenolsulfonyl compound of the formula ##STR1## wherein R is C.sub.1 -C.sub.12 alkyl, cycloalkyl, phenyl, benzyl, or phenyl which is substituted by halogen, lower alkyl, lower alkoxy, nitro or methylenedioxy, and

Novel phosphonic acid salts produced from ethane- or methanephosphonic acid, dicyandiamide and/or guanidine and optionally ammonia and corresponding to the formula ##STR1## wherein n, p, q, t and y are each 1 or 2, are particularly suitable for fireproofing organic fibre materials. Synthetic and/or cellulose-containing fibre materials are treated with an aqueous solution of the phosphonic acid salts and are then dried preferably at 60.degree. to 200.degree. C. The applied phosphonic acid salts impair only negligibly the textile-mechanical properties of the treated fibre materials, especially of the cellulose-containing fibre materials dried at 120.degree. to 150.degree. C.

Process for fireproofing organic fibre material using phosphonic acid

Phosphonic acid salts, their preparation and their use for fireproofing

A process for the non-permanent flameproofing of organic fibrous materials with monoammonium or monoalkali metal salts of an alkylphosphonic acid is claimed. Monoammonium methyl- and ethylphosphonate are also claimed. The claimed process is suitable for a very wide variety of fibrous materials. The flame-retardants used according to the invention have no corrosive action and have excellent compatability with most other textile finishing agents.

Process for flameproofing organic fibrous material with phosphonic acid

A process for fireproofing polyester fibers is provided in which a substituted mono- or disulphurylamide of the formula ##STR1## wherein n is 1 or 2, R are aromatic, cycloaliphatic or aliphatic radicals or hydrogen and A is alkylene or an ammonium salt of such a sulphurylamide is applied to the fiber material which is then dried and subjected to a heat treatment. The sulphurylamide may also be applied in the presence of a dispersant, a protective colloid and/or water. The composition of matter for performing this process is also provided.

Compositions for fireproofing polyester fiber materials with substituted

The invention provides a fireproofing composition which contains at least

Method for the fireproofing of synthetic fiber material

A process is provided for flameproofing cellulosics in which an aqueous solution is applied thereto which contains

Process for flameproofing cellulosic fibrous material

The subject of the invention is a process for the manufacture of polycondensation products of hydroxymethylphosphonium compounds and an amine, characterized in that (a) 1 mol of a tetrakis-(hydroxymethyl)-phosphonium compound is condensed with 0.02 to 0.3 mol, preferably 0.02 to 0.25 mol, of an amine at 100.degree. to 150.degree. C., optionally in the presence of an inert organic solvent, if appropriate free hydroxyl groups are at least partially etherified with at least one alkanol with 1 to 4 carbon atoms and if appropriate the salts of the polycondensation products are converted into the corresponding hydroxides. The condensation products are used for flameproofing organic fiber material, especially textiles.
