摘要： Photographic elements comprising certain 2-phenylcarbamoyl-1-naphthol image-modifying couplers exhibit proper hue, a resistance to dye crystallization, and a resistance to leuco cyan dye formation. Such couplers can be utilized for their image-modifying effect and can contribute substantially to the overall dye density of an image.

摘要： heterocyclic N-(acylhydrazinophenyl)thioamide nucleating agents are disclosed as well as radiation-sensitive compositions and elements containing such nucleating agents in combination with silver halide grains capable of forming an internal latent image. The elements can be used to form direct-positive photographic images. Dye image transfer photographic elements are specifically contemplated.A specifically preferred compound class comprised of a combination of preferred moieties can be indicated by the formula: ##STR1## wherein: A is .dbd.N--R.sup.2, --S-- or --O--;Q.sup.3 is represented by the formula ##STR2## X is .dbd.S or .dbd.O; T.sup.1 is ##STR3## or --H.sub.2 ; R.sup.3 is an alkyl substituent:R.sup.4 is hydrogen, an alkyl, ##STR4## or an alkoxy substituent; Z represents the non-metallic atoms necessary to complete a basic 5- or 6-membered heterocyclic nucleus of the type found in cyanine dyes having ring-forming atoms chosen from the class consisting of carbon, nitrogen, oxygen, sulfur and selenium;n and d are independently chosen from the integers 1 and 2;R.sup.8 is hydrogen, phenyl, methyl, ethyl, propyl or butyl;R.sup.9 is a meta- or para-phenylene group;R.sup.2, r.sup.5 and R.sup.6 are independently chosen from hydrogen, phenyl, alkyl, alkylphenyl and phenylalkyl; andThe alkyl moieties in each instance include from 1 to 6 carbon atoms.
