This relates to a dye represented by Formulae II and IIA below:
1
wherein;
R
1
represents a hydrogen, an aryl group containing 6 to 14 carbon atoms, or an alkyl group containing 1 to 12 carbon atoms;
R
2
and R
3
together form an aromatic, carbocyclic or heterocyclic ring system containing 6 to 14 atoms;
X represents a sulfoxide (S═O), sulfone (SO
2
), or dicyanovinyl (C(CN)
2
) group;
Y represents a sulfoxide (S═O), sulfone (SO

2
) group;
L
1
, L
2
, and L
3
represent 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;
