Corrosion-inhibiting coating compositions

A batchwise process for dyeing hydrophobic fibres at 110.degree. C. to 135.degree. C. with a disperse dye in the presence of an adduct of an average of 1 to 4 molar proportions of ethylene oxide, propylene oxide or styrene oxide or a combination of these oxides with 1 molar proportion of a phenol compound having the formula ##STR1## in which n is a number from 1 to 4,

Process for the dyeing of hydrophobic fibres

New piperidine derivatives of 1,3-pyrimidine and 1,3,5-triazine are used as stabilizers for organic materials, especially for polymers.

Piperidine derivatives

A process for the colouration of polyacrylonitrile textile fibres, wherein said fibres are coloured by printing or pad-steaming with a cationic dye in the presence of a carrier consisting of least one compound having the formula ##EQU1## in which Y is an oxygen or sulphur atom and m is a number from 1 to 2, obtaining on said fibres a rapid fixation of the cationic dye and a high colour yield.

Process for the colouration of acrylic fibres

Process for the colouration of acid-modified synthetic textile fibres, particularly polyacrylonitrile fibres or basic dyeable polyester fibres, wherein said fibres are coloured with a cationic dye in the presence of a compound of the formula ##EQU1## wherein R is a chloro-substituted phenyl group, Z is hydrogen or methyl and n is an integer from 1 to 3, obtaining on said fibres a rapid fixation of the cationic dye and an outstanding colour yield.
