摘要:
An image-forming method is described using a light-sensitive material comprising a support and a light-sensitive layer on the support, said light-sensitive layer containing an o-quinonediazide compound as a first component and a basic carbonium dye as a second component; according to this method images can be obtained both by positive working and negative working techniques. Furthermore, images which are free from yellow light fogging can be obtained by use of a laser beam.
摘要:
A process for producing a sheet-like material having a vapor-deposited metallic layer thereon, which comprises vapor depositing a layer of a metal, a layer of different metals in contact with each other, a layer of a metal alloy, a layer of a metal and a metal compound in contact with each other or a layer of a metal compound as the metallic layer on a support of a polymeric material having a glass transition temperature of at least about 0.degree.

摘要:
A negative-working image forming process which comprises uniformly exposing a photosensitive material comprising a support having thereon a sensitive layer comprising (i) an o-quinonediazide compound and (ii) a second compound, to actinic radiation which is able to convert the o-quinonediazide compound to the corresponding indenecarboxylic acid compound, and subsequent to said uniformly exposing imagewise exposing said exposed photosensitive material to a laser beam to thereby render the indenecarboxylic acid compound of the imagewise exposed areas convert to the corresponding indene compound and developing with an alkaline developing solution to dissolve out the unexposed area to the laser beam, wherein said second compound reduces the rate of dissolution of the laser exposed areas in the developing solution by converting the indenecarboxylic acid to the corresponding indene compound, whereby said image results.
