Title (EN) CURABLE PHOTOCHROMIC COMPOSITION INCLUDING A SEGMENTED POLYMER
(FR) COMPOSITION PHOTOCHROMIQUE DURCISSABLE COMPRENANT UN POLYMÈRE SEGMENTÉ
Abstract:
(EN) The present invention relates to a curable photochromic composition that includes: (a) a photochromic compound; and (b) a segmented polymer that includes active hydrogen groups, at least one first segment, and at least one second segment, in which, (i) each first segment independently includes a (meth)acrylic polymer segment, and (ii) each second segment independently includes at least one of, a polycarbonate segment, a polyester segment, a polyether segment, a polyurethane segment, and combinations of two or more thereof. The curable photochromic composition further includes (c) a curing agent having reactive functional groups that are reactive with the active hydrogen groups of the segmented polymer (a), in which the curing agent includes at least one of, a polyisocyanate, a polyisothiocyanate, and an aminoplast. The present invention also relates to photochromic articles that include at least one layer formed from the curable photochromic composition of the present invention.
(FR) La présente invention concerne une composition photochromique durcissable qui comprend : (a) un composé photochromique ; et (b) un polymère segmenté qui comprend des groupes hydrogène actifs, au moins un premier segment et au moins un deuxième segment, (i) chaque premier segment comprenant indépendamment un segment de polymère (méth)acrylique et (ii) chaque deuxième segment comprenant indépendamment au moins l'un parmi un segment de polycarbonate, un segment de polyester, un segment de polyéther, un segment de polyuréthane et des combinaisons de deux ou plus correspondantes. La composition photochromique durcissable comprend en outre (c) un agent de durcissement présentant des groupes fonctionnels réactifs qui sont réactifs avec les groupes hydrogène actifs du polymère segmenté (a), l'agent de durcissement comprenant au moins l'un parmi un polyisocyanate, un polyisothiocyanate et un aminoplaste. La présente invention concerne également des articles photochromiques qui comprennent au moins une couche formée à partir de la composition photochromique durcissable de la présente invention.
