摘要： A non-silver, positive-working, essentially alkali-insoluble, radiation-sensitive composition, which becomes alkali-soluble on exposure to radiation, comprising a non-silver, positive-acting, essentially alkali-insoluble radiation-sensitive component a radiation absorbing component and an essentially alkali-soluble polymeric binder. A radiation-sensitive element comprising a transparent substrate overcoated with said radiation-sensitive composition. A duplicating film comprising the said element prepared by exposing said composition through the substrate and then image-wise exposing said composition through a mask in front of the composition followed by treatment with an alkaline developer to remove those areas of the composition subjected to both exposures.

摘要： Imagable articles comprising positive working polymeric resins coating onto substrates are given a heat treatment comprising their controlled slow cooling from an elevated temperature. The imagable articles include precursors for lithographic printing plates and for printed circuits. The controlled slow cooling improves the development characteristics of the coatings after an imaging step.
