Abstract: Process for the preparation of I acid urea of the formula in which 7-amino-4-hydroxynaphthalene-2-sulphonic acid (I acid) is subjected to partial reaction with urea in an inert solvent at a temperature from 100 to 140 DEG C and a pressure from atmospheric pressure to 10 bar, unreacted I acid is precipitated in an acidic medium and removed, and, if appropriate, I acid urea is separated from the resulting neutralised solution by adding salt.

Abstract: New rhodamine de4rivs. are 3,6-diamino-8-(2-carboxyphenyl) -xanthylium salts of formula (I). In (I) R1-4 = H or (substd.) 1-4C alkyl, or R2+R5 or R4 + R6 = 1,3-propylene, opt. with up to three 1-4C alkyl substit(s).; R5-8 = H or Me; R9 = H, (substd.) 1-4C alkyl or (C2H4O-)nH with n = 2 or 3, An(+) = the equiv. of an anion derived from a polymer or polycondensate contg. acid gps. (I) can be prepd. (not claimed) by dissolving the neutral dye base in e.g. water and/or lower alcohols and treatment with a polymer or polycondensate contg. acid gps.. USE/ADVANTAGE - (I) are used for dyeing polyacrylonitrile fibres, pigmenting polymers or in ink prodn. (claiemd). They are also useful in the prodn. of electrophotographic toners or fluorescent pigments and have better light fastness than commercially available rhodamines.
