PHOTOCHROMIC COMPOSITE MATERIAL

摘要: PURPOSE:To obtain a photochromic composite material having resistance to abrasion, heat and chemicals, by successively laminating, on substrate, an org. polymer contg. spirooxazine compd. three-dimensional crosslinked capacity of forming hard coat. CONSTITUTION:A comprising substrate and, laminated thereon, the following coating films (A) (B) in that order. Coating film is formula, wherein R , are each H, 1-2C alkyl, alkoxy, halogen, or nitro; phenyl, naphthyl, substituted derivative thereof; n integer 1-5. capable coat, it may be any as far can improve abrasion (A). However, hardened made organopolysiloxane particularly pref. from viewpoint adhesion thereof capability hardening at low temp. short period time.
