Abstract

The prepn. of oxanol methine dyes of formula (I) (where L, L' and L" are opt. substd. methine gps., n is 0 or 1 and Z are non metal atoms completing a 5 or 6 membered heterocyclic ring) comprises condensing a heterocyclic ketomethylenic deriv. of formula (II): with a methine gp. providing cpd, in presence of a lower carboxylic acid, N,N-dialkyl amide, specifically di(m)ethylformamide or di(m)ethylacetamide. The dyes are formed directly in the anionic acid form without recourse to an auxiliary step, e.g. treatment with HCl, which necessitates careful filtration. Used as filter or antihalodyes in photographic prods.
