Beschreibung
Zusammenfassung:	The present invention provides a method for manufacturing a photochromic article having a photochromic compound containing layer. The method includes the step of coating a casting face of at least one mould section with a photochromic host layer. The photochromic host layer is treated to minimise damage during subsequent steps, and a mould is then assembled so that it includes the mould section having the photochromic host layer. The mould is then filled with a photochromic article monomer composition and the monomer composition is subsequently cured to form a photochromic article substrate adhered to the photochromic host layer. The photochromic compound is introduced into the photochromic host layer.
