Abstract

Disclosed are styryl dyes of formula

wherein
R 1 , R 2 , R 3 , R′ 1 , R′ 2 and R′ 3 independently of each other are hydrogen; —NH(CO)—C 1 -C 5 alkyl; —N(C 1 -C 5 alkyl)(C 1 -C 5 alkyl-CN); C 1 -C 6 alkoxy; a heterocyclic radical; or R 1 and R 2 or R′ 1 and R′ 2 together form a 5- to 10-membered, monocyclic, carbocyclic or heterocyclic ring; wherein at least one of R 1 , R 2 , R 3 , R′ 1 , R′ 2 and R′ 3 is different from hydrogen; Q and Q′ independently from each other are the direct bond; *—C(O)—*; *—C(O)O—*; *—OCO—*; *—N(R 4 )—*;

 *—C(O)N(R 6 )—*; or *—(R 6 )NC(O)—*; and

R 4 , R 5 and R 6 independently from each other are hydrogen; C 1 -C 14 alkyl; C 2 -C 14 alkenyl; C 6 -C 12 aryl; C 6 -C 12 aryl-C 1 -C 10 alkyl; or C 1 -C 10 alkyl(C 5 -C 12 aryl);
X and X′ are *—(CH 2 ) m —*;
Y 1 and Y 2 independently from each other are C 1 -C 10 alkylene; C 5 -C 10 cycloalkylene; C 5 -C 12 arylene; or C 5 -C 12 arylene-(C 1 -C 10 alkylene);
An − is an anion;
m is a number from 1 to 8;
n is 0, or 1; and
p is 0, or 1.
