| description | The present invention relates to a curable photochromic composition comprising (a) a photochromic compound; (b) a segmented polymer having an active hydrogen group, at least one first segment and at least one second segment wherein (i) each first segment independently comprises a fluorinated polymer segment and (ii) each second segment independently comprises a segment selected from the group consisting of polycarbonate segments, polyester segments, polyether segments, polyurethane segments, and segments of copolymers thereof; and (c) a curing agent having a reactive functional group reactive with the active hydrogen group of the segmented polymer, wherein the curing agent includes at least one of a polyisocyanate, a polyisothiocyanate, or an aminoplast. Also provided are photochromic films and articles, including multilayer articles, comprising the curable photochromic compositions.
本发明涉及一种可固化光致变色组合物，其包含(a)光致变色化合物；(b)具有活性氢基团、至少一个第一链段和至少一个第二链段的分段聚合物，其中(i)每个第一链段独立地包含氟化聚合物链段，并且(ii)每个第二链段独立地包含选自聚碳酸酯链段、聚酯链段、聚醚链段、 |
