also be developed in the exposed element by washing off the unexposed soluble part with a solvent or thermally transferring the unexposed unhardened part into the image receiving material or other known methods in the method of washing off with a solvent not only organic solvents but also alkaline aqueous solutions can be used as a developing solvent examples of suitable developing solutions include a solution of an alkali carbonate such as sodium carbonate a solution of an alkali hydroxide such as sodium hydroxide a mixture thereof an aqueous solution containing a lower alcohol such as ethanol isopropanol etc and an alkanolamine such as ethanolamine propanolamine 2 diethylaminoethanol etc and their analogues the presence of s surface active agent in the developing solution can further clear development of the elements an alkali strength of the developing solution depends on the characteristics of the composition used also the developing solution can contain dyes pigments and so on the developed images are rinsed with distilled water and dried after drying the exposed images may further be exposed if desired the present invention will now be described by reference to the following specific example which is not meant to be limiting unless otherwise specified all percents ratios.
