further wherein for the spirooxazine represented by Formula (II) one of R1, and R2, independently comprise said first reactive group and one of R3, R4, R5 and R6 comprise said second reactive group, (b) an indenonaphthopyran represented by the following Formula (III), wherein x is from 1 to 4, y is from 1 to 4, R7 independently for each x, R8 independently for each y, R9, and R10 are each independently selected from hydrogen, hydrocarbyl and substituted hydrocarbyl each optionally interrupted with at least one of —O—, —S—, —C(O)—, —C(O)O—, —OC(O)O—, —S(O)—, —SO2—, —N(R11)—, and —Si(R11)(R12)— wherein R11 and R12 are each independently selected from hydrogen, hydrocarbyl and substituted hydrocarbyl, and combinations of two or more thereof, andB and B′ are each independently selected from unsubstituted aryl, substituted aryl, unsubstituted heteroaryl, substituted heteroaryl, and polyalkoxy, or B and B′ taken together form a ring structure selected from unsubstituted fluoren-9-ylidene, substituted fluoren-9-ylidene, saturated spiro-monocyclic hydrocarbon ring, saturated Spiro-bicyclic hydrocarbon ring, and spiro-tricyclic hydrocarbon ring,provided that for the indenonaphthopyran represented by Formula (III), two of, R7, R8, R9, R10, B, and B′ each independently comprise said reactive group that is independently bonded to one monomer residue M,wherein the indenonaphthopyran represented by Formula (III) comprises one first reactive group, and one second reactive group,
further wherein for the indenonaphthopyran represented by Formula (III) one of B and B′ comprise said first reactive group, and one of R7, R8, R9 and R10 comprise said second reactive group. |
