    • The present invention provides a method of forming a desired pattern with a coating on a substrate. The method includes the steps of applying a water soluble resist material in a predetermined pattern to a surface of a substrate, drying the resist material, depositing a coating on the surface of the substrate to form a coated substrate, wherein a portion of the coating overlays the resist material, and dissolving the resist material on the coated substrate with water to remove the resist material and corresponding overlaying coating and form a desired coating pattern on the substrate surface. The dissolving step preferably includes the step of directing high temperature and high pressure water sprays at the surface of the coated substrate to wash off the resist and corresponding overlaying coating. The removal of the resist material may include a prewash operation wherein the surface of the substrate is wetted with water and coating is allowed to soak. The present invention also discloses a resist material for masking selected portions of a glass sheet to form a desired coating pattern. The resist material includes 1-20 wt. % water soluble polymer film former, 0 to 3 wt. % surfactant, 0 to 5 wt. % rinse aid and a solvent. The film former, surfactant and rinse aid are preferably all soluble in the solvent. In one particular embodiment of the invention, the film former is selected from a group consisting of polyvinylpyrrolidone, polyvinylalcohol, sodium alginate, hydroxyethyl cellulose and combinations thereof, the rinse agent is selected from a group consisting of sodium bicarbonate, sodium hydrogen phosphate, sodium sulfate, inorganic salts and combinations thereof, and the solvent is water, an organic solvent or a combination thereof.
    • 本发明提供了一种用基材上的涂层形成所需图案的方法。 该方法包括以下步骤:将预定图案的水溶性抗蚀剂材料涂覆到基材的表面上,干燥抗蚀剂材料,在基材表面上沉积涂层以形成涂覆的基材,其中涂层的一部分覆盖 抗蚀剂材料,并且用水将抗蚀剂材料溶解在涂覆的基材上以除去抗蚀剂材料和相应的覆盖涂层,并在基材表面上形成所需的涂层图案。 溶解步骤优选包括在涂覆的基材的表面上引导高温高压喷水以洗去抗蚀剂和相应的覆盖涂层的步骤。 抗蚀材料的去除可以包括预洗操作,其中衬底的表面被水润湿并且允许涂层浸泡。 本发明还公开了一种用于掩蔽玻璃板的选定部分以形成所需涂层图案的抗蚀剂材料。 抗蚀剂材料包括1-20重量% %水溶性聚合物成膜剂,0〜3重量% %表面活性剂,0至5wt。 %漂洗助剂和溶剂。 成膜剂,表面活性剂和漂洗助剂优选全部溶于溶剂中。 在本发明的一个具体实施方案中,成膜剂选自聚乙烯吡咯烷酮,聚乙烯醇,藻酸钠,羟乙基纤维素及其组合,漂洗剂选自碳酸氢钠,磷酸氢钠,硫酸钠 ,无机盐及其组合,溶剂为水,有机溶剂或其组合。
