    • WHEREIN U denotes a diphenyl radical bonded in the 4,4''-position to the oxazole rings and U1 and U2 denote naphthalene radicals fused to the oxazole rings, and wherein up to four positions capable of substitution in U; U1 and U2 can be substituted with optionally substituted alkyl groups, halogen or optionally functionally modified sulphonic acid groups and up to 2 positions capable of substitution can be substituted with optionally substituted phenyl groups, phenylalkyl groups, -SO2-phenyl, nitrile or optionally functionally modified carboxyl groups. The naphthoxazole compounds are useful as optical brightening agents.

      The present invention relates to new azole derivatives of the naphthoxazole type which in the most general case correspond to the formula
