ABSTRACT:
This relates to a dye represented by Formulae II and IIA below:wherein;R1represents a hydrogen, an aryl group containing 6 to 14 carbon atoms, or an alkyl group containing 1 to 12 carbon atoms,R2and R3together form an aromatic, carbocyclic or heterocyclic ring system containing 6 to 14 atoms;X represents a sulfoxide (S═O), sulfone (SO2), or dicyanovinyl (C(CN)2) group;Y represents a sulfoxide (S═O), sulfone (SO2), carbonyl (C═O) or dicyanovinyl (C(CN)2) group;L1, L2, and L3represent methine groups, wherein the methine groups may combine to form a 5- or 6-membered ring when m is equal to or >1;m is 0, 1, 2, or 3;W is an aryl group; andD is a moiety in conjugation with the X and Y groups.
