摘要：
This invention relates to a polymerizable composition for forming a photochromic article having a glass transition temperature of at least 50° C. on curing the composition comprising: (a) a polymerizable composition comprising a monomer component; and (c) a photochromic dye monomer comprising a photochromic moiety and at least one oligomer group having at least one group reactive with the monomer component during curing wherein the oligomer group comprises at least seven polyether monomer units selected from alkylenoxy and haloalkylenoxy.
