Abstract: Derivatives of 2,4,6-tris-[(p-carboxy)-anilino]-5-triazine are described, which can be used as light stabilisers for synthetic polymers and for the preparation of cosmetic and dermatological compositions.

Abstract: The invention relates to novel polypiperidine compounds which give polymer materials high stability against oxidation and degradation when exposed to light, and to the process for the production thereof.

Abstract: A process for the elimination of the fluorescence effect resulting from the treatment of fibrous materials with optical anionic agents is described which consists of treating the fibrous materials with a water soluble salt of a polymer containing the imidazoline ring of formula I ##STR1## wherein X is in the position meta or para with respect to the imidazoline ring and X is ##STR2## or --CO--NH-- The imidazoline-containing compounds prepared by reacting diethylenetriamine or triethylenetetramine with terephthalic or isophthalic acid followed by cyclization are reacted with dicyandiamide. The water soluble salt is an acid addition salt or a quaternary ammonium salt. The new polymers are described.

Abstract: Water-soluble acid addition or quaternary ammonium salts of compounds produced by acylation of an excess of diethylene triamine by isophthalic or terephthalic acid or a functional derivative thereof, subsequently cyclizing the product to afford imidazoline groups, and reacting the product further by way of acylation with a bifunctional acylating agent which is a saturated aliphatic dicarboxylic acid or a functional derivative thereof, or a functional derivative of carbonic acid. Such salts are useful for eliminating or preventing the brightening effect on materials, e.g. such fibrous material as textiles and paper, of anionic optical brightening agents.

Abstract: A method for eliminating or preventing the brightening effect on materials, particularly fibrous materials such as textiles and paper, of anionic optical brightening agents involving the use of hydrosoluble acid addition salts or quaternary ammonium salts of compounds containing the group of formula: ##STR1## wherein the benzene radical is linked within the group at its m- or p-positions.

Abstract: The invention provides a process for increasing the affinity for anionic dyes of undyed water-insoluble high molecular weight organic compounds containing groups which can be alkylated, which process comprises reacting the high molecular weight compound with an ammonium salt of the formula: ##EQU1## in which X signifies chlorine or bromine.Y signifies a radical of formula --CH=CH-- or a phenylene radical which is unsubstituted or substituted by up to a total of 2 alkyl groups which may be methyl or ethyl,R.sub.1, r.sub.2 and R.sub.3, independently signify hydrocarbon radicals consisting of aromatic and/or saturated aliphatic units, orTwo of R.sub.1, R.sub.2 and R.sub.3 jointly with the N atom form a heterocyclic ring, which is selected from heterocyclic rings containing one nitrogen atom, two nitrogen atoms and one nitrogen atom and one oxygen atom, and the other signifies a hydrocarbon radical as defined above or a further bond when the ring is unsaturated,The total number of carbon atoms in R.sub.1, R.sub.
