摘要：
The invention relates to novel naphthopyrans having a cyclic group annelated in position 6, 7. These naphthopyrans have formula (I). These compounds (I) have advantageous photochromic properties. The invention also covers the method of preparing these naphthopyrans, as well as their applications as photochromes : compositions and (co)polymers matrices comprising them.
