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: 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.
