Photochromic coating composition comprising nanoscales particles and process for providing substrate coated with the same |
摘要 |
A photochromic coating composition contains a silicon-containing precondensate derived from a hydrolysable silane containing a polymerizable functional group on a hydrolysis-stable radical, a photochromic dye, a stabilizer, and nanoscale particles. The coating composition, when applied to transparent plastic and glass substrates and cured, gives a coating having high light stability and good scratch resistance.
