Disclosed is a photographic element comprising a silver halide emulsion layer having associated therewith a dye-forming coupler represented by Formula I: ##STR1## wherein R' represents the group ##STR2## in which R.sup.1, R.sup.2, and R.sup.3 independently selected all groups, provided that any two of R.sup.1, R.sup.2, and R.sup.3 may join to form a ring;

Photographic element containing magenta coupler having improved

Magenta image-dye couplers provide photographic elements and processes having superior photographic properties. The couplers are 3-anilino pyrazolone couplers having an aryl thio coupling-off group. The substituents of the coupler are specified to obtain advantageous properties.

3-anilino pyrazolone magenta couplers and process

Dye fade in photographic images prepared from a silver halide photographic element having a light sensitive silver halide emulsion layer and a pyrazoloazole dye forming coupler is reduced by using a combination of stabilizer compounds of formula S, formula I and optionally formula R. ##STR1##

Photographic elements containing magenta dye forming couplers and fade

A silver halide photographic element comprising a light sensitive silver halide containing layer which also contains a 2-equivalent pyrazolone magenta coupler, a thiomorpholine dioxide compound which has an alkoxy substituted aryl group substituent on the ring nitrogen, a compound of formula (I) below, and a hydroquinone compound of formula (R) below: ##STR1## wherein: R.sub.3, R.sub.4 and R.sub.31 are independently an alkyl group or H; R.sub.11, R.sub.12 and R.sub.21 are alkyl groups. The presence of the compound (I) when used with the two-equivalent pyrazolone magenta coupler and compounds (R) and (S), can result in a photographic element with low printout and/or thermal discoloration problems.

Photographic elements containing 2-equivalent pyrazolone magenta dye

A silver halide photographic element having a light sensitive silver halide which layer also contains a 2-equivalent pyrazolone magenta coupler, a compound of formula (S) below, and a hydroquinone compound of formula (R) below: ##STR1## wherein: R.sub.1 is an alkyl group; and R.sub.2, R.sub.3 and R.sub.4 are independently an alkyl group or H. The presence of the compound (S) when used with the two-equivalent pyrazolone magenta coupler and compound (R), can result in low magenta dye fade, increased wavelength of maximum absorption of the magenta dye and increased magenta dye bandwidth.

The present invention relates to 2-substituted-1-hydroxyindoles of the following formula: ##STR1## wherein, R.sup.1 is an electron withdrawing group,

2-substituted-1-hydroxyindoles

1-Hydroxyindoles of the following formula are useful in controlling fungi: ##STR1## wherein: R.sup.1 is hydrogen or an electron withdrawing group;
