Abstract: The present invention is directed to correction tapes having dye migration blocking properties. More specifically, the present invention includes a correction tape having a dye migration barrier. The dye migration barrier comprises an organic material that serves as a physical barrier to prevent dye from migrating from the lower corrected layer to the visible surface. Additionally, the present invention is directed to a process for the manufacture of a correction tape having a dye migration barrier.

Abstract: Disclosed is a waterproofing membrane that comprises a carrier sheet, a pressure sensitive adhesive layer on one surface of the carrier sheet, and a protective coating layer on the adhesive layer. The protective coating layer comprises a vinyl acetate copolymer (i.e., a copolymer of vinyl acetate and a comonomer) having a Tg of 10°C to 35°C. The protective coating layer protects the membrane against weather exposure, tolerates foot traffic and strongly adheres to concrete cast against it.
Abstract translation: 公开了一种防水膜，其包括载体片，载体片的一个表面上的压敏粘合剂层和粘合剂层上的保护涂层。 保护性涂层由Tg为10℃〜35℃的乙酸乙烯酯共聚物（即乙酸乙烯酯和共聚单体的共聚物）组成。 保护涂层保护膜免受天气暴露，容忍脚部流动并强烈地粘附在其上。
