Abstract: Compounds of the formula (I) wherein X is O or S, R1 and R2 each are hydrogen, fluorine, chlorine, phenyl, alkyl, alkoxy, dialkylamino, trialkylammonium, acylamino or optionally functionally modified carboxy or sulfo groups, two adjacent radicals R1 and R2 optionally forming together a phenylene, a lower alkylene or a 1,3-dioxapropylene group; and A is a group of the formulae in which R3 is an alpha-, beta- or gamma-pyridyl, pyridyl-methylene, thiophenyl, furanyl, benzofuranyl, pyrazinyl, pyrimidinyl or pyridazinyl group. These compounds, which are suitable as optical brighteners, are prepared by reaction of a compound of the formula with a compound of the formula R3-Z wherein Y is a group and Z is -COCl or vice versa.

Abstract: A mixture of optical brighteners containing 0.05 to 0.95 part by weight of a compound from the benzoxazolyl- or benzothiazolylstilbene series and 0.95 to 0.05 part by weight of a compound of the bis-benzoxazolyl- or bis-benzothiazolylstilbene series or of the benzoxazolyl- or benzothiazolyl-stilbene oxazolo[5,4-6]pyridinyl or oxazolo[2,3-b]pyridinyl series. These mixtures show an enhanced degree of whiteness as compared to the same amount of the single components.
