摘要： A spiro(indolino) oxazine compound of general formula (I), wherein R1 represents a group of the formula -NR2R3, wherein each of R2 and R3, which may be the same or different, independently represents an alkyl group, or a carbocyclic group, preferably aryl, or a heterocyclic group, or R2 and R3 taken together with the nitrogen atom to which they are attached represent a heterocyclic ring having one or more heteroatoms and which may optionally carry at least one substituent selected from alkyl, aryl or heteroaryl groups; R4 represents an alkyl group which may be linear, branched or alicyclic; each of R5 and R6, which may be the same or different, represents an alkyl group or a carbocyclic or heterocyclic group, or R5 and R6 taken together with the carbon atom to which they are attached represent a carbocyclic or heterocyclic ring which may optionally carry at least one substituent selected from alkyl, aryl or heteroaryl groups; R7 represents a hydrogen atom or an alkyl, aryl or heteroaryl group, or a carbocyclic or heterocyclic group which is fused to heterocyclic ring B; R8 represents a hydrogen atom or a substituent selected from alkyl, alkoxy, aryl, aryloxy, heteroaryl, halogen, azo, imino, amide, ester, cyano, trifluoromethyl or nitro group, or a dialkylamino group; -X- is selected from -O-, -S-, -Se-, -NH- or -NR- wherein R represents an alkyl group, and ring A is a carbocyclic or heterocyclic ring which can be optionally substituted with a group of formula R8 as defined above, or may optionally have a carbocyclic or heterocyclic ring fused thereto. The spiro(indolino) oxazine compounds of the invention are useful as photochromic materials in lenses, e.g., sunglasses, and photochromic transparencies for cars and aricrafts.

摘要： A naphthopyran compound of general formula (I) wherein R1 represents an alkyl group or an aryl group; each of R4 and R5, which may be the same or different, independently represents an alkyl, alkenyl, carbocyclic or heterocyclic group, or R4 and R5 taken together with the carbon atom to which they are attached form a carbocyclic ring or a heterocyclic ring; and R6 represents a hydrogen atom or a substituent selected from alkyl, alkoxy, aryl, aryloxy, heteroaryl, halogen, amino, substituted amino, azo, imino, amide, carboxylate, ester, cyano, trifluromethyl or nitro, and in addition R6 may represent a carbocyclic or heterocyclic ring fused to ring A. The naphthopyran compounds of the invention are useful as photochromic materials in lenses, e.g. sunglasses, and photochromic transparencies for cars and aircrafts.
