A REACTIVE SPIRONAPHTHOXAZINE COMPOUND, A PHOTOCROMIC POLYMETHACRYLIC POLYMER COATING COMPOSITION CONTAINING THE SPIRONAPHTHOXAZINE COMPOUND, A PHOTOCROMIC POLYMETHACRYLIC POLYMER GRAFTED WITH THE SPIRONAPHTHOXAZINE, AND A PHOTOCHROMIC OPTICAL ARTICLE COMPRISING THE SAME

摘要

The present invention is responsive spiro naphthoxy group photo (spironaphthoxazine) compounds, photochromic comprising the polymethyl acrylic coating solution composition, the photochromic polyacrylic and relates to a photochromic optical product comprising the same, and more particularly to the formula (1) than the responsive spiro naphthoxy group photo compounds, photochromic polyacrylic coating liquid composition containing the same represented by, responsive spiro naphthoxy group photo relates to grafted photochromic polyacrylamide, and the photochromic optical product comprising the same . ; Photochromic poly acrylic coating composition of the present invention as including a responsive spiro naphthoxy group photo compound that can be grafted directly to a polyacrylamide molecule, without the phase separation occur among the coating solution, a photochromic coating film produced therefrom is no blooming (blooming) phenomenon with the lapse of time, can last for a long time it has the advantage that the photochromic. ; [Formula 1] ; Wherein X ¹ to X ³ have the same structure and the detailed description of the invention. ; Responsive, photochromic, spiro naphthoxy group photo, polyacrylonitrile, graft, the coating film
