APPENDIX
26. A presensitized plate which comprises a roughened
and anodized aluminum support having provided thereon two
positive working light-sensitive layers, one of which layers
being a light-sensitive layer adjacent to or near the support and
comprising an ester obtained by reacting 1,2-naphthoquinone-2-
diazide-5-sulfonyl chloride with a polyhydroxy compound and an
alkali-soluble resin that becomes soluble in a developer upon
exposure to light and the other light-sensitive layer comprising
an ester obtained by reacting 1,2-naphthoquinone-2-diazide-5-
sulfonyl chloride with a polyhydroxy compound, an alkali-soluble
resin and a dye that becomes soluble in a developer upon exposure
to light, wherein a dye concentration in the light-sensitive
layer adjacent to or near the support is lower than that in the
other light sensitive-layer, and said two light-sensitive layers
are obtained by (i) coating on the support a first photosensitive
solution being free of a dye and containing the ester obtained by
reacting 1,2-naphthoquinone-2-diazide-5-sulfonyl chloride with a
polyhydroxy compound, the alkali-soluble resin and a solvent to
form the light-sensitive layer adjacent to or near the support,
(ii) then coating a second photo-sensitive solution including the
ester obtained by reacting 1,2-naphthoquinone-2-diazide-5-
sulfonyl chloride with a polyhydroxy compound, the alkali-soluble
resin, the dye and a solvent to form the other light-sensitive
layer, and (iii) then drying the light-sensitive layers thereby
forming the two positive working light-sensitive layers.
27. A presensitized plate which comprises an aluminum
support, a surface of which is grained and anodized, and two
positive working light-sensitive layers on said surface, one of
which layers being a light-sensitive layer adjacent to or near
the support and comprising an o-naphthoquinone diazide compound
and an alkali-soluble resin that becomes soluble in a developer
upon exposure to light and the other light-sensitive layer
comprising an o-naphthoquinone diazide compound, an alkali-
soluble resin and a dye that becomes soluble in a developer upon
exposure to light, wherein the o-naphthoquinone diazide compound
contained in the two light-sensitive layers are identical, a dye
