Process for preparing a mask for sandblasting |
摘要 |
A process for preparing a mask for sandblasting, in which there is employed a transparent soluble peel-aid film layer superimposed on a transparent protective film layer to cover a liquid photopolymerizable composition layer. According to the process, the protective film can be readily stripped and a mask for sandblasting which has a strong adherence to articles to be engraved can be produced efficiently without occurrence of troubles, such as chipping of high-precision portions, e.g. fine dots and lines, of polymeric images.
