Non-photosensitive aqueous blockout composition and blockout method for repairing flaws |
摘要 |
The invention resides in a photosensitive composition for screen printing. Preferably, the composition of the invention comprises a polymer comprising a vinylpyridine monomer or polymer having a pyridinium salt character and a photoreactable constituent. The resulting stencil, once dried, exposed, cured, and subjected to alkaline treatment obtains enhanced solvent/water resistance but can be reclaimed using an acidic wash. In use, the stencil provides a screen/stencil assembly or blockout utility of high structural integrity through repeated use and screen printing images of high resolution and quality.
