ADHESIVE PHOTOCHROMIC MATRIX LAYERS FOR USE IN OPTICAL ARTICLES |
| 摘要 |
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. |
