| titleOfInvention | Process for the production of salts of stilbene-azo and stilbene-azoxy dyes |
| abstract | Salts of stilbene-azo and stilbene-azoxy dyestuffs, and mixtures thereof inhich the cations are selected from tetra-alkylammonium, tetraalkylammonium in combination with lithium, sodium, potassium or ammonium, and ammonium in combination with lithium, sodium or potassium, have good cold water solubility relative to known salts of such dyes. n The preferred dyes have the formula ##STR1## wherein (1) EACH R' is independently --SO 3 .sup.⊖ M.sup.⊕ or --SO 3 .sup.⊖ N.sup.⊕ (R) 4' n wherein each R is independently alkyl of 1 to 6 carbon atoms or alkyl of 1 to 6 carbon atoms substituted by hydroxy, cyano, halo or phenyl, and n Each M.sup.⊕ is independently hydrogen, lithium, sodium, potassium or ammonium, with the proviso that at least one R' is --SO 3 .sup.⊖ N.sup.⊕ (R) 4' n (2) each R' is --SO 3 .sup.⊖ M.sup.δ, n wherein each M.sup.⊕ is lithium, sodium, potassium, or ammonium, with the proviso that at least one M.sup.⊕ is ammonium, or n (3) each R' is independently --SO 3 .sup.⊖ M.sup.⊕ or --SO 3 .sup.⊖ N.sup.⊕ (R) 4' n wherein each R is independently alkyl of 1 to 6 carbon atoms or alkyl of 1 to 6 carbon atoms substituted by hydroxy, cyano or halo, and n each M.sup.⊕ is ammonium or an alkali metal, with the proviso that at least one R' is --SO 3 .sup.⊖ M.sup.⊕ wherein M.sup.⊕ is ammonium. n The dyes are useful for producing colored paper by incorporation into paper stock or by application to paper sheet. The dyed paper is fast to light and wet treatments. |
