Abstract:
1. A naphthopyran represented by the following graphic formula: wherein, (a) R wherein each Y being independently chosen for each occurrence from —CH 2 —, —CH(R 17 )—, —C(R 17 ) (R 17 )—, —CH(aryl)—, —C(aryl) 2 — or —C(R 17 ) (aryl)—; X being —Y—, —O—, —S—, —S(O)—, —S(O 2 )—, —NH—, —N(R 17 )— or —N(aryl)—; R 17 being C 1 -C 6 alkyl; said aryl group being phenyl or naphthyl, m being chosen from the integer 1, 2 or 3 and p being chosen from the integer 0, 1, 2 or 3; provided that when p is 0, X is Y; wherein each R 19 , R 20 and R 21 being chosen independently for each occurrence in each formula from hydrogen, C 1 -C 5 alkyl, phenyl or naphthyl; or the groups R 19 and R 20 together form a ring of 5 to 8 carbon atoms; R 18 being chosen independently for each occurrence from C 1 -C 6 alkyl, C 1 -C 6 alkoxy, fluoro or chloro and n being chosen from the integer 0, 1 or 2; (b) R (c) R wherein —Z being chosen from —C(O)— or —CH 2 —, Z′ being chosen from C 1 -C 3 alkoxy or a polymerizable group, x, y and z each being independently chosen from a number between 0 and 50, and the sum of x, y and z being between 2 and 50; (d) R wherein Y, X, m and p being the same as described hereinbefore in (a) (iii); or wherein R 18 , R 19 , R 20 , R 21 and n being the same as described hereinbefore in (a) (iv); (e) R (f) R (g) R wherein J and K being independently chosen for each occurrence in each formula from oxygen or —N(R 15 )—, R 15 being the same as described hereinbefore in (a) (ii), R 19 and R 20 each being the same as described hereinbefore in (a) (iv); (h) B and B′ are each independently chosen from: wherein A being independently chosen in each formula from methylene or oxygen and D being independently chosen in each formula from oxygen or substituted nitrogen, provided that when D is substituted nitrogen, A is methylene; said nitrogen substituents being chosen from hydrogen, C 1 -C 6 alkyl, or C 2 -C 6 acyl; each R 24 being independently chosen for each occurrence in each formula from C 1 -C 6 alkyl, C 1 -C 6 alkoxy, hydroxy, chloro or fluoro; R 22 and R 23 each being independently chosen in each formula from hydrogen or C 1 -C 6 alkyl; and q being chosen from the integer 0, 1 or 2; wherein L being chosen from hydrogen or C 1 -C 4 alkyl and M being chosen from an unsubstituted, mono-, or di-substituted group chosen from naphthyl, phenyl, furanyl, or thienyl; each of said group substituents being independently chosen from C 1 -C 4 alkyl, C 1 -C 4 alkoxy, fluoro, or chloro; or (ix) B and B′ taken together form fluoren-9-ylidene, mono-, or di-substituted fluoren-9-ylidene or a group being independently chosen from saturated C
