摘要

Disclosed are styryl sulfide dyes of formula (1), wherein R₁, R'₁, R₂, R'₂, R₃ and R'₃, independently from each other are hydrogen; C₁-C₂₀alkyl or C₁- C₂₀alkoxy, which may be substituted by one or more C₁-C₅alkoxy, halogen, -NH₂, mono-C₁-C₅alkylamino, di-C₁-C₅alkylamino, -NO₂ or hydroxy; C₃-C₆cycloalkyl; -C(O)H; -C(O)-C₁-C₅alkyl; halogen; NO₂; OH; phenyl, which may be substituted by one or more C₁-C₅alkyl, C₁-C₅alkoxy, halogen, -NH₂, mono-C₁-C₅alkylamino, di-C₁-C₅alkylamino, -NO₂ or hydroxy; or a radical of formula -NR₄R₅, wherein R₄ and R₅ independently from each other are hydrogen; C₁-C₁₂alkyl, which may be substituted by one or more C₁-C₅alkyl, C₁-C₅-alkoxy, hydroxy or -(CO)-H; -(CO)-C₁-C₅alkyl; phenyl or phenyl-C₁-C₄alkyl, wherein the phenyl moiety may be substituted by one or more C₁-C₅alkyl, C₁-C₅alkoxy, halogen, -NH₂, mono-C₁-C₅alkylamino, di-C₁-C₅alkylamino, -NO₂, carboxy or hydroxy; W₁, W'₁, W₂, W'₂, W₃, W'₃, W₄ or W'₄, independently from each other are -CH- or -N⁺-; wherein only one of W₁/W'₁, W₂/W'₂, W₃/W'₃, W₄/W₄' is -N⁺; and the bivalent radical -Q-Z-Y-S-S-Y'-Z'-Q'- is bonded to W₁ or W₂ and W'₁ or W'₂ respectively; Y₁ and Y₂ independently from each other are C₁-C₁₀alkylene; C₅-C₁₀cycloalkylene; C₅-C₁₂arylene; or C₅-C₁₂arylene-(C₁-C₁₀alkylene); Q and Q' independently from each other are the direct bond; or -C(O)-; -C(O)O-; -OCO-; -N(R₆)-; formula (AA); -C(O)N(R₆)-; -(R₆)NC(O)-; -O-; -S-; -S(O)-; or -S(O)₂-; and R₆ and R₇ independently from each other are hydrogen; C₁-C₁₄alkyl; C₂-C₁₄alkenyl; C₆- C₁₂aryl; C₆-C₁₂aryl-C₁-C₁₀alkyl; or C₁-C₁₀alkyl(C₅-C₁₂aryl). Further, the present invention relates to novel styryl sulfide compounds, compositions thereof, especially comprising other dyes, and to processes for their preparation.
