Abstract: Novel pyrazolines are obtained by condensation of substituted propiophenones or vinyl-phenyl-ketones with substituted phenyl hydrazines. The products are useful as optical brighteners of a great variety of the shade of their fluorescence and of an improved fastness to light.

Abstract: Brighteners for detergents consisting of a mixture of 4,4'-bis-(2-morpholino-4-anilino-1,3,5-triazinylamino)-stilbene-2,2'-d isulfonic acid-di-Na salt and from 5 to 50% by weight, calculated on said brightener, of another brightener of the formula +TR in the above formula, M is an alkali metal cation, preferably sodium, X is a group of the formula -COR2 or -SO2R3, R2 being C1-C8-alkyl and R3 being C1-C5-alkyl, C4-C8-cycloalkyl, phenyl or toluyl, Y is hydrogen or C1-C5-alkyl, A is C3-C6-alkylene, R1 is hydrogen, C1-C5-alkyl, C4-C8-cycloalkyl, or a group of the formula and Z is an anilino group, a chloroanilino group or a morpholino group. Said brightener mixtures are color-stable and do not show any green discoloration even after a prolonged storage in a moist atmosphere.

Abstract: BIS-(TRIAZINYLAMINO)-STILBENE-DISULFONIC ACID DERIVATIVES of the disclosure: 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.
