An aqueous composition for sandblast resist ink comprising an aqueous dispersible polymer having a minimum film-forming temperature of 10°C or lower and a water-soluble polymer as a film-forming auxiliary agent, and a method of sandblasting using the aqueous composition are disclosed. The aqueous composition produces a sandblast resist ink which can produce a dry film having a degree of swelling in the range of 0.1-1.5 in water at 20°C. The resist mask can be produced by using this aqueous composition as the sandblast resist ink without using any organic solvents in all steps (e.g. the resist mask formation step and the resist mask removed step) of sandblast processing for producing relief of photographic images, patterns, letters, or characters on the surface of glass, stones, ceramics, metals, plastics, woods, and the like.
本发明公开了一种用于喷砂抗蚀油墨的
水性组合物,该组合物包含一种最低成膜温度为 10°C 或更低的
水性可分散聚合物和一种作为
成膜助剂的
水溶性聚合物,以及一种使用该
水性组合物进行喷砂的方法。
水性组合物可产生一种喷砂抗蚀油墨,该油墨在 20°C 的
水中可产生膨胀度在 0.1-1.5 范围内的干膜。使用这种
水性组合物作为喷砂抗蚀油墨,可以在喷砂处理的所有步骤(例如抗蚀层形成步骤和抗蚀层去除步骤)中不使用任何有机溶剂而产生抗蚀层,从而在
玻璃、石头、陶瓷、
金属、塑料、木材等表面产生浮雕摄影图像、图案、字母或字符。
