Abstract
In a process for the production of uniformly coloured polyurethane foams, a pigment or dyestuff in the form of a paste with a liquid of boiling point not less than 160 DEG C. is admixed with at least one of the reactants prior to any substantial chemical reaction taking place. The apparatus described in Specification 769,680 can be employed to effect the mixing, the paste being injected into the mixing zone through a nozzle, preferably simultaneously with but independently of the other ingredients. Liquids specified are alkyl esters or halogenated alkyl esters of phosphoric acid, glycerine triacetate, benzyl octyl adipate, dioctyl phthalate, esters of the fatty acids obtained by the oxidation of paraffins, aliphatic or aromatic hydrocarbons and halogenated hydrocarbons. Azo dyestuffs, phthalo-cyanins, indanthrenes and inorganic pigments may be used, a list being given. The paste can be formed using the dispersion-kneader described in Specification 687,021, [Group II]. Specification 769,682, [Group II], also is referred to.ALSO:In a process for the production of uniformly coloured polyurethane foams, a pigment or dyestuff in the form of a paste with a liquid of boiling point not less than 160 DEG C. is admixed with at least one of the reactants prior to any substantial chemical reaction taking place.
