使用有机溶剂前处理及光致变色涂层制备光致变色光学物件的方法;METHOD OF PREPARING A PHOTOCHROMIC OPTICAL ARTICLE USING AN ORGANIC SOLVENT PRETREATMENT AND PHOTOCHROMIC COATING

摘要

本发明提供一种制备光致变色光学物件之方法，其包括：(i)将第一有机溶剂施加至光学基材之表面，由此在该光学基材上形成有机溶剂润湿之表面；以及(ii)将可固化光致变色涂料组合物施加在该光学基材之该有机溶剂润湿之表面上，由此在该光学基材之该表面上形成可固化光致变色涂层。该可固化光致变色涂料组合物包括第二有机溶剂，且该第一与第二有机溶剂彼此可互溶。在一些实施例下，第一与第二有机溶剂相同。; and (ii) applying a curable photochromic coating composition over the organic solvent wetted surface of said optical substrate, thereby forming a curable photochromic coating layer over the surface of the optical substrate. The curable photochromic coating composition includes a second organic solvent, and the first and second organic solvents are miscible with each other. With some embodiments, the first and second organic solvents are the same.
