Abstract:
The invention relates to a photochromic polymeric composition comprising a polymer matrix and a photochromic compound which is an adduct comprising a photochromic moiety and at least one pendant oligomer group to provide a rate of fade of the photochromic polymeric composition which is significantly changed when compared with the corresponding composition comprising the photochromic compound without said pendent oligomer.The invention also relates to a photochromic compound which is an adduct comprising a photochromic moiety and at least one pendent oligomer.
