The present invention relates to naphthopyrans, particularly 3,3-[substituted]- naphtho[2,1-b] pyrans and 2,2-[substituted]-naphtho[1,2-b]pyrans and particularly to novel substitution on the 3-position and 2-position, respectively, of these naphthopyrans. It has been found that there are classes and types of substitution on the 3-position and 2-position (especially combinations of 3,3-substitution and 2,2- substitution) which are novel. Some of these substitutions provide particularly desirable properties. In particular, the present invention relates to naphthopyrans wherein one 3-substituent or one 2-substituent comprises a phenyl group (including phenyl, substituted phenyl, biphenyl or substituted biphenyl) and the other 3-position or other 2-position substituent comprises a substituted or unsubstituted group selected from the group consisting of anthranilyl, azepinyl, benzoxazolyl, diazepinyl, dioazlyl, imidazolidinyl, imidazolyl, imidazolinyl, indazolyl, indoleninyl, indolinyl, indolizinyl, indolyl, indoxazinyl, isobenzazolyl, isoindolyl, isooxazolyl, isooxazyl, isopyrroyl, isoquinolyl, isothiazolyl, morpholino, morpholinyl, oxadiazolyl, oxathiazolyl, oxathiazyl, oxathiolyl, oxatriazolyl, oxazolyl, piperazinyl, piperazinyl, piperazyl, piperidyl, purinyl, pyranopyrrolyl, pyrazinyl, pyrazolidinyl, pyrazolinyl, pyrazolyl, pyrazyl, pyridazinyl, pyridazyl, pyridyl, pyrimidinyl, pyrimidyl, pyridenyl, pyrrolidinyl, pyrrolinyl, pyrroyl, quinolizinyl, quinuclidinyl, quinolyl, thiazolyl, triazolyl, and triazyl.
