Abstract: A photoresist film and application thereof are provided. The photoresist film has a thickness T with a unit of ?m, and when the photoresist film is characterized by ultraviolet-visible spectroscopy, the photoresist film has an absorbance A405nm at 405 nm and an absorbance A436nm at 436 nm, wherein 0<A405nm/T?0.006 and 0<A436nm/T?0.005, and the thickness T is 60 ?m to 600 ?m.

Abstract: Nondiffusible compounds are described having at least one releasable 2-(2-heterocyclylazo)-1-naphthol dye moiety having the formula: ##STR1## wherein: G is hydroxy, a salt thereof, or a hydrolyzable precursor thereof; or a group which together with ##STR2## is CAR, said CAR being bonded to the naphthalene group through the oxygen of said ##STR3## group; Z represents the atoms necessary to complete a heterocyclic ring;CAR represents a ballasted carrier moiety; andt is a positive integer of 1 to 2.

Abstract: Photographic elements, diffusion transfer assemblages and processes are described which employ a novel nondiffusible compound having a releasable azo dye moiety. The compound has the formula: ##STR1## wherein: G is a metal chelating group (or a salt or hydrolyzable precursor thereof) or a group which together with a ##STR2## group is CAR (bonded through the oxygen); G.sup.1 is a hydroxy group (or a salt or hydrolyzable precursor thereof);Z is an electron withdrawing group;Z' is alkyl, aryl or N(R).sub.2 (R being H, alkyl or aryl);CAR is a ballasted carrier moiety; andt is 0 or 1.The dye can be transferred imagewise to an image-receiving layer where it can be contacted with metal ions to form a metal-complexed azo dye transfer image of excellent stability. The retained dye image in the photographic element can also be bleached, fixed and metallized to form a color transparency or a motion picture film.

Abstract: Photographic elements, diffusion transfer assemblages and processes are described which employ a novel nondiffusible compound having a releasable 2-(2-heterocyclylazo)-1-naphthol dye moiety which contains a nitrogen atom adjacent to the point of attachment to the azo linkage. The compound contains a ballasted carrier moiety which is capable of releasing the diffusible azo dye under alkaline conditions. The dye is transferred imagewise to an image-receiving layer where it is contacted with metal ions to form a metal-complexed azo dye transfer image of excellent stability.
