Abstract: Novel 1,3,4-oxadiazolone-(2) compounds of the formula (1) wherein Y denotes carboxy optionally functionally modified or optionally substituted phenyl or a five-membered heterocycle optionally substituted and selected from the group consisting of: furan, thiophen, oxazole, imidazole, oxadiazole, oxadiazolone, triazole, benzofuran, thionaphthalene, benzoxazole, benzimidazole, and benzotriazole, R denotes hydrogen, alkyl or optionally substituted phenyl, n denotes 0 and 1 and the rings A and B carry optionally further non-chromophoric substituents. These compounds may be used as optical brighteners.

Abstract: Condensation compounds of 2 mols of cyanuric acid with 1 mol of 4,4'-diaminostilbene-2,2'-disulfonic acid, at least two mols of a lower alkylene diamine which is acylated at one nitrogen atom and, optionally, another two mols of another amine or an alcohol or a phenol are useful as optical brighteners, especially for cellulosic and polyamide materials.

Abstract: Mixtures of optical brighteners containing 0.05 to 1% of a 4-benzoxazolystilbene derivative and 1 to 0.05% of a 1,4-bis-benzoxazolyl- or bis-benzthiazolyl-naphthalene derivative. These mixtures show a higher degree of whiteness than an equal amount of only one of the two components.

Abstract: Novel benzofuran containing a benzimidazolyl group are obtained by reacting a benzofuran containing a carboxylic acid halide group with either an ortho-phenylene diamine or an ortho-nitro-aniline derivative, in the latter case reducing the nitro intermediate to the corresponding (aminophenyl)-amide and splitting off water by closing the imidazole ring. The products are optical brighteners, especially for acrylonitrile polymers.
