A photochromic polyurethane laminate wherein the photochromic polyurethane layer of the laminate has been crosslinked with an isocyanate-active prepolymer using a crosslinking agent. The crosslinking agent is formulated to have at least three functional groups that are reactive with functional groups of the polyurethane or of the isocyanate-active prepolymer. A method of making the photochromic polyurethane laminate includes steps of causing the crosslinking.

Photochromic polyurethane laminate

The present invention pertains to polyurethane-urea based optical adhesives for formation of optical film laminates, optically functional film laminates, and ophthalmic or eyeglass lenses employing the same and methods for producing the same.
