Photographic element containing antifogging cycanine dyes

A photographic element comprising at least one light-sensitive layer comprising a silver bromide or iodobromide emulsion and a dye of formula (I) or formula (II):

• ##STR22## wherein:
• each L is a substituted or unsubstituted methine group, n is 0 or 1;
• R.sub.1 and R.sub.2 are substituted or unsubstituted alkyl groups;
• V is a 4-methoxy or 6-methoxy group;
• W.sub.1 -W.sub.4 are independently hydrogen, alkyl, halogen, aryl, heteroaryl, alkylthio or alkoxy, with the proviso that no more than one of W.sub.1 -W.sub.4 is alkoxy, or W.sub.2 and W.sub.3 or W.sub.3 and W.sub.4 can be a fused ring;
• and
• X.sub.1 and X.sub.2 are independently S or Se;
• ##STR23## wherein:
• each L' is a substituted or unsubstituted methine group, n' is 0 or 1;
• R.sub.3 and R.sub.4 are substituted or unsubstituted alkyl groups;
• V.sub.1 is a 4-methoxy or 6-methoxy group;
• W.sub.5 -W.sub.8 are independently hydrogen, alkyl, halogen, aryl, heteroaryl, alkylthio or alkoxy, with the proviso that no more than one of W.sub.5 -W.sub.8 is alkoxy and if n' is 1, none of W.sub.5 -W.sub.8 is aryl, or W.sub.6 and W.sub.7 or W.sub.7 and W.sub.8 can be a fused ring;
• and
• X.sub.3 is S or Se.
