Process for production of positive images using sulfonic acid precursors |
摘要 |
Positive images are produced by (i) exposing to actinic radiation in a predetermined pattern a composition supported on a substrate, which composition comprises a film-forming organic material and a substance which releases a sulphonic acid on exposure to actinic radiation, thereby rendering the composition more soluble in the developer in the exposed areas than the unexposed areas, and (ii) treating the composition with the aqueous base developer to remove the unexposed areas. The image-forming process may be used in the production of printing plates and electrical circuits.
