A process for forming an image which comprises heating a light-sensitive material comprising a support having thereon at least a light-sensitive silver halide, a binder and a dye-releasing redox compound which is reductive to the light-sensitive silver halide and which is capable of releasing a hydrophilic dye upon reaction with the light-sensitive silver halide on heating, after imagewise exposure or simultaneously with imagewise exposure, in a substantially water-free condition the dye-releasing redox compound being represented by the formula (I) wherein R represents a phenyl group having a hydroxy-substituted alkoxy group or an alkoxy-substituted alkoxy group at at least the 2-position thereof with respect to the diazo group and a group of the formula --SO.sub.2 NH--Y at the 5-position thereof with respect to the diazo group where Y represents a group capable of being oxidized silver halide to release a dye moiety including the --SO.sub.2 NH moiety.
A photographic light-sensitive material comprising a support having thereon at least one light-sensitive silver halide emulsion layer having associated therewith a compound represented by formula (I) ##STR1## wherein Q represents a cyano group, a trifluoromethyl group, or a carbamoyl group represented by the formula --CONR.sup.1 R.sup.2 (wherein R.sup.1 represents a hydrogen atom, an alkyl group, or a substituted alkyl group, and R.sup.2 represents a hydrogen atom, an alkyl group, a substituted alkyl group, an aralkyl group, or an aryl group, or R.sup.1 and R.sup.2 may combine directly or through an oxygen atom to form a ring); M represents an alkyl group, a substituted alkyl group, an alkoxy group, a substituted alkoxy group, or a halogen atom; E.sup.1 represents a hydrogen atom, a halogen atom, an alkyl group, a substituted alkyl group, a hydroxyl group, an alkoxy group, or a substituted alkoxy group (provided that the substituted alkoxy group is not present at the para-position with respect to the azo group); E.sup.2 represents a substituent defined for E.sup.1 or an electron attractive group selected from a cyano group, a trifluoromethyl group, a group represented by the formula --SO.sub.2 R.sup.4 (wherein R.sup.4 represents an alkyl group, a substituted alkyl group, a phenyl group, or a substituted phenyl group), a group represented by the formula --COOR.sup.3 represents a hydrogen atom, an alkyl group, a substituted alkyl group, a phenyl group, or a substituted phenyl group), a group represented by the formula --CONR.sup.1 R.sup.2 (wherein R.sup.1 and R.sup.2 are each defined above), a sulfo group and a group represented by the formula --SO.sub.2 NR.sup.1 R.sup.2 (wherein R.sup.1 and R.sup.2 are each the same as defined above); m and q each represents 0 or 1; J represents a divalent group selected from a sulfonyl group and a carbonyl group; Z represents a hydrogen atom, an alkyl group, or a substituted alkyl group; X represents a divalent bonding group represented by the formula --A.sub.1 --(L).sub.n --(A.sub.2).sub.p -- (wherein A.sub.1 and A.sub.2 each represents a substituted or unsubstituted alkylene group or a substituted or unsubstituted arylene group, L represents a divalent group selected from an oxy group, a carbonyl group, a carboxyamido group, a carbomoyl group, a sulfonamido group, a sulfamoyl group, a sulfinyl group, and a sulfonyl group, and n and p each represents 0 or 1); and Y represents a moiety which provides, as a result of development processing, an azo dye compound having a different diffusibility from that of the azo dye image-forming compound of formula (I).
The present invention relates to a class of 5-haloalkyl-3-hydroxy-1-(C.sub.1-2 alkyl)pyrazoles useful as precursors for an active class of phenoxypyrazole herbicides.
