PHOTOCHROMIC CURABLE COMPOSITION |
摘要 |
A photochromic curable composition comprising 100 parts by mass of polymerizable monomers which include 70 to 100 mass % of polymerizable monomers having two to four (meth)acrylic groups and 0 to 30 mass % of a polymerizable monomer having one (meth)acrylic group and 0.01 to 20 parts by mass of a photochromic compound, wherein the number of moles of the methacrylic group existent in the polymerizable monomer composition is 3 to 7 times the number of moles of the acrylic group. This composition can provide a lens having a photochromic coating which exhibits excellent photochromic properties, comprises a hard coat layer having sufficiently high adhesion and scratch resistance and has no delay in fading and has excellent storage stability.
