1. Photochromic fused naphthopyrans of the formula (II):, in which the radical R1, or R1 and R3 independently of one another, is/are the following moiety:, in which the radical R13 is hydrogen or a methyl radical and the radical R14 is a substituent selected from hydrogen, a (C1-C6)-alkyl radical, an acetyl radical, a benzoyl radical, a phenyl radical, a benzyl radical, a biphenylyl radical, a naphthyl radical, a tert-butyldimethylsilyl radical or a tert-butyldiphenylsilyl radical; n is an integer from 0 to 1, and p is an integer from 3 to 50; or, if R13 is a methyl radical, R14 may also be the moiety —(CH2—CH2)q—OR15, in which case the radical R15 may be selected from hydrogen, a (C1-C6)-alkyl radical, a phenyl radical, a benzyl radical or a biphenylyl radical, and q is an integer from 1 to 20; and
the radicals R2, R3 and R4 in each case independently of one another are a substituent selected from hydrogen, bromine, chlorine, fluorine, a (C1-C6)-alkyl radical, a (C3-C7)-cycloalkyl radical, a (C1-C6)-thioalkyl radical, a (C1-C18)-alkoxy radical, a hydroxyl radical, a tert-butyldimethylsilyloxy radical, a tert-butyldiphenylsilyloxy radical, a trifluoromethyl radical, a phenyl radical, a 4-methoxyphenyl radical, a phenoxy radical, a 4-methoxyphenoxy radical, a benzyl radical, a 4-methoxybenzyl radical, a benzyloxy radical, a 4-methoxybenzyloxy radical, a biphenylyl radical, a diphenylyloxy radical, a naphthyl radical, a naphthoxy radical, a mono-(C1-C6)-alkylamino radical, a di-(C1-C6)-alkylamino radical, a phenylamino radical, a (C1-C6)-alkyl-phenylamino radical, a diphenylamino radical, a (4-methoxyphenyl)amino radical, a ((C1-C6)-alkyl)-(4-methoxyphenyl)amino radical, a bis(4-methoxyphenyl)amino radical, a piperidyl radical, a 3,5-dimethylpiperidyl radical, an indolinyl radical, a morpholinyl radical, a 2,6-dimethylmorpholinyl radical, a thiomorpholinyl radical, an azacycloheptyl radical, a phenothiazinyl radical, a phenoxazinyl radical, a 1,2,3,4-tetrahydroquinolyl radical, a 1,2,3,4-tetrahydroisoquinolyl radical, a phenazinyl radical, a carbazolyl radical, a 1,2,3,4-tetrahydrocarbazolyl radical or a 10,11-dihydrodibenz[b,f]azepinyl radical;
or the two adjacent radicals R2 and R3 are the moiety —V—(CH2)r—W—, in which case V and W independently of one another are selected from the moieties —O—, —S—, —N(C1-C6)-alkyl-, —NC6H5—, —CH2—, —C(CH3)2—, —C(C2H5)2— or —C(C6H5)2—; r is an integer from 1 to 3; with the proviso that if this numerical value is 2 or 3, there may also be a benzene ring fused to two adjacent CH2 groups; V or W, together with the respectively adjacent CH2 group, may also be a fused benzene ring;
or R3 is the same moiety as R1;
the radicals R5, R8, R9, R10, R11 and R12 each independently of one another are a substituent selected from hydrogen, a (C1-C6)-alkyl radical, a (C3-C7)-cycloalkyl radical, a phenyl radical, a benzyl radical, a biphenylyl radical or a naphthyl radical; where m is an integer from 1 to 3;
or two adjacent radicals R5 form a fused benzene ring, which may be unsubstituted or mono- or disubstituted, in which case the substituents may be selected from hydrogen, a (C1-C6)-alkyl radical, a (C1-C6)-alkoxy radical, a phenyl radical, a benzyl radical, a biphenylyl radical or a naphthyl radical;
or two adjacent radicals R5 form a fused benzofuran ring, a fused benzothiophene ring, a fused 2H-chromene ring, a fused 3,3-dimethylindene ring or a fused dioxane ring;
or the radicals R8 and R9 together form the moiety —(CH2)s—, in which case s is an integer from 1 to 3; with the proviso that if this numerical value is 2 or 3, there may also be a benzene ring fused to two adjacent CH2 groups.
