ABSTRACT:
Benzoxazole derivatives represented by general formula (I) which are intermediates for synthesis of o-sulfonamidophenol derivatives useful as dye releasing redox compounds in a color diffusion transfer color image forming process: ##STR1## wherein R.sup.1 and R.sup.2, which may be the same as or different from each other, each represents an alkyl group or an aryl group or they may combine and form a ring; R.sup.3 represents a hydrogen atom, an alkyl group or an aryl group; R.sup.4 represents an alkyl group or an aryl group; R.sup.5 represents an alkyl group, an alkoxy group, an alkylthio group, an arylthio group, a halogen atom or an acylamino group, or --CR.sup.1 R.sup.2 R.sup.3 and R.sup.5 may combine and form the nucleus ##STR2## which is condensed at the 6- and the 7-positions of the benzoxazole nucleus; and n is 0, 1 or 2.
