1,4-Bis-styrylbenzene derivs. ≮I; R, R1 = H, halogen, lower alkyl, lower alkoxy; A, A1 = halogen, -OH, lower alkyl, substitutable lower alkylene; X, X1 = -COOM, -SO3M(M = H, alkali metals, alkali earth metals, organic ammonium, guanidium); R2 = lower alkyl, phenyl≉were prepd. by reaction of 1,4-xylene phosphoric ester derivs. (II), compd. (III) and benzaldehyde derivs. (IV). The compds. (I) are heat- and alkalistable fluorescent whiteners imparting a clear white appearance to natural and synthetic fibers, detergents, paper, and plastics.
