    • A photochromic compound has the formula (I) wherein R1 is selected from the group including substituted amino aryl moieties, substituted cyclic amino aryl moieties and substituted N-indolinoaryl or N-tetrahydroquinolino aryl groups, R3 is selected from the group including linear or branched C1-C20 alkyl, linear or branched C2-C20 alkenyl or polyalkenyl, C2-C20 alkynyl or polyalkynyl, aryl, heteroaryl, linear or branched C1-C20 alkyl aryl, linear or branched C1-C20 alkyl-cycloalkyl or -bicycloalkyl or -tricycloalkyl or substituted -cycloalkyl or -bicycloalkyl or -tricycloalkyl, linear or branched C1-C20 haloalkyl or perhaloalkyl, linear or branched C1-C20 alkoxyalkyl or peralkoxyalkyl, linear or branched C1-C20 alkylthioalkyl or peralkylthioalkyl, linear or branched C1-C20 amino alkyl or peraminoalkyl, C3-C20 cycloalkyl or substituted cycloalkyl, C4-C20 bicycloalkyl or substituted bicycloalkyl, C6-C20 tricycloalkyl or substituted tricycloalkl or linear or branched C1-C20 hydroxyalkyl or perhydroxyalkyl; R4 and R5 which may be the same or different are R3 or R4 and R5 are conjoined to form a spiro linked C3-C20 cyclic system or substituted cyclic system; and wherein R2 and R6 are each selected from R3 or hydrogen, halogen, nitro, nitroso, amino, acetamido, C2-C10 N-alkylamido, alkoxycarbonyl, nitrile, carboxy, hydroxy, aryloxy, C1-C10 alkoxy, a heteroatom which is O or N or S or P which in turn can be bonded either singly or multiply to carbon, oxygen, sulphur or nitrogen, C1-C5 alkoxy or alkylthio or aryl or aryloxy or multiples thereof.
