A novel dye and photographic element comprising the dye are detailed. The dye is especially useful as an antihalation dye in a photographic element. A particularly preferred embodiment is provided in a photographic element comprising an absorbing amount of the dye: ##STR1## wherein X1, X2 independently represents --CR.sup.8 R.sup.9 --, --S--, --Se--, --NR.sup.10 --, --CH.dbd.CH-- or --O--;

Silver halide photographic element containing dyes for antihalation

A novel dye and photographic element comprising the dye are detailed. The dye is especially useful as an antihalation dye in a photographic element. A particularly preferred embodiment is provided in a photographic element comprising an absorbing amount of the dye: ##STR1## wherein X.sup.1, X.sup.2 independently represents --CR.sup.8 R.sup.9 --, --S--, --Se--, --NR.sup.10 --, --CH.dbd.CH-- or --O--;

Photographic element with ether dyes for near-infrared antihalation

An improved dye class and preparation procedure therefore is provided. The dyes can be prepared from a Stenhouse salt which is economical and can be prepared from readily available reagents. The improved dye is particularly suited for use as an antihalation dye in photographic elements and does not impart deleterious properties thereto. These and other properties are provided in a dye represented by: ##STR1## wherein the constituents have defined values.

Near-infrared absorbing dyes prepared from stenhouse salts

Disclosed is a photographic element comprising an antihalation dye of formula: ##STR1## wherein X.sup.1, X.sup.2 independently represents --CR.sup.8 R.sup.9 --, --S--, --Se--, --NR.sup.10 --, --CH.dbd.CH-- or --O--;
