Abstract
The present invention provides a method for forming images comprising the steps of imagewise exposing a negative-working image-forming material which comprises a substrate provided thereon with an image-recording layer comprising a photopolymerization initiator system sensitive to light rays whose wavelength falls within the visible to ultraviolet ranges, a polymerizable compound carrying at least one ethylenically unsaturated group and a binder polymer and then developing the imagewise exposed image-forming material with a developer which contains at least one carbonate, at least one hydrogen carbonate and at least one alkali silicate and which has a pH value ranging from 9 to 13.0, wherein the ratio of the total molar number a of the carbonate and the hydrogen carbonate to the molar number b of the SiOcomponent present in the alkali silicate: a/b ranges from 1:0.3 to 1:2 and the total molar number of these components: a+b ranges from 0.1 to 2 mole/L. The present invention provides a stable processing method even when an image-forming material having a narrow latitude (small discrimination) in developing is utilized.
