  The present invention relates to a composition for depositing a temporary, selectively soluble protective coating onto a substrate and a process for using the same. The composition consists essentially of a copolymer consisting of 35 to 85 weight percent vinyl acetate and from 15 to 65 weight percent of a predefined monoalkyl maleate which is dispersed in a solvent/vehicle. The protective coatings deposited therefrom are substantially impervious to aqueous media having acidic or neutral pH and provide an effective barrier against damage to the substrate's surface. At the desired time, the protective coating can be removed from the substrate by dissolution in an aqueous alkaline solution.

  本发明涉及一种在基材上沉积临时性、选择性可溶保护涂层的组合物及其使用方法。该组合物主要由 35 至 85 重量百分比的醋酸乙烯酯和 15 至 65 重量百分比的预定马来酸单烷基酯共聚物组成，该共聚物分散在溶剂/载体中。由此沉积的保护涂层基本上不受酸性或中性 pH 值的水介质的影响，并能有效地防止基材表面受损。在需要的时候，保护层可以通过溶解在碱性水溶液中从基底上去除。
