Adhesive matrix layers (24) and sublayers and methods for their preparation are described. The adhesive matrix layers (24) and sublayers provide effective reservoirs for photochromic additives and can serve as an effective transition region between dissimilar materials to be used in optical articles which transmit or refract light.

L'invention concerne des couches (24) et des sous-couches matricielles adhésives ainsi que des procédés pour leur préparation. Ces couches (24) et sous-couches matricielles adhésives constituent des réservoirs efficaces d'additifs photochromiques et peuvent faire office de région de transition efficace entre des matériaux dissemblables destinés à être utilisés dans des articles optiques transmettant ou réfractant la lumière.
