摘要:
A planographic printing plate material comprising a support and a light sensitive layer provided on the support, the light-sensitive layer being composed of (A) an inorganic material; (B) at least one metal and/or metal compound [(A)/(B) are capable of reacting with each other upon application of electromagnetic radiation] and (C) an organic compound capable of affecting the reaction between the inorganic material (A) and the metal and/or metal compound (B), wherein the inorganic material (A), the metal or metal compound (B), and the organic compound (C) are in contact with each other. When the light-sensitive layer is exposed to electromagnetic radiation, a difference in the hydrophilic or oleophilic nature of the exposed areas and the unexposed areas results, whereby a planographic printing plate is obtained which can be mounted on a printing machine and printed without any other treatments.

摘要:
A light-sensitive material having on a support a light-sensitive layer containing an o-quinonediazide compound as a main component and, additionally, a particular compound represented by the following general formula (I): ##STR1## wherein Z represents the nonmetallic atoms forming a 5-membered ring; X represents S, O, ##STR2## or .dbd.N--R.sub.c (where R.sub.a, R.sub.b and R.sub.c are each a hydrogen atom or an organic group other than a carboxylic acid group); and Y is a hydrogen atom or an organic group other than a carboxylic acid group, is disclosed. This material can provide both positive and negative working images having high resolution and good adhesiveness to the support. A process for producing positive working images includes the steps of imagewise exposure and development processing, while a process for producing negative working images includes the steps of imagewise exposure, heating, uniform (overall) exposure and development processing. The same conditions regarding imagewise exposure and development processing, respectively, can be applied to both processes.
