NOVELTY - The novel naphthopyran compound (I) is 3,3-bis(aryl)-5-(N-(un)substituted)amido)naphthopyrans.    USE - For ophthalmic, solar articles (claimed).    ADVANTAGE - The lens obtained using photochromic compound has higher maximum absorption spectrum, increased optical induced density, lower transmission after 15 minutes exposure to UV light.    DETAILED DESCRIPTION - The novel naphthopyran compound is 3,3-bis(aryl)-5-(N-(un)substituted)amido)naphthopyrans of formula (I).    R1, R2 = hydrogen, 1-4C or 1-2C alkyl, 3-12C cycloalkyl, optionally substituted aryl, 6-24C aryloxy, (heteroaryl)oxy with 4-24C, hetero atom containing sulfur, oxygen or nitrogen, and the substituent is halogen such as fluorine, chlorine or bromine, 1-6C alkoxy, 1-6C haloalkyl preferably trifluoromethyl, 2-12C alkenyl or alkynyl preferably vinyl or alkyl or R'''(which is 1-6C alkyl, nitro, amine) or NHR group were R = 1-6C alkyl, NR'R;    R',R = 1-6C alkyl, or together form 5-7 membered ring optionally substituted by R''';    R3, R4, R5 = halogen such as F, Cl or Br, 1-12C preferably 1-6C alkyl, 3-12C cycloalkyl, 2-12C alkenyl or alkynyl, 1-12C or 1-6c alkoxy or alkylthio, halo(cyclo)alkyl, haloalkoxy, electron withdrawing group such as CN, NO2 or SCN group, amine or amide, -OCOR6 or -COOR6;    R6 = H, 1-6C alkyl, 3-6C cycloalkyl or optionally substituted phenyl with substituents similar to R1 R2;    m,n,p = at least 2.    R3, R4, R5 combines with aromatic ring of 5 or 6 membered, 5-7C aliphatic ring, hetero atom containing oxygen, sulfur or nitrogen. R1 and R2 bonded to nitrogen atom form morpholino, piperidino, piperazino or indolino group. INDEPENDENT CLAIMS are also included for the following:    (i) method of preparing naphthopyron compound in which acetylide salt is reacted with benzophenone compound (II) to form propynol of formula (III), which is further reacted with 2 hydroxy 3 naphthamide of formula (IV) to form naphthopyron compound;    (ii) photochromic compound which comprises at least 2 compound of naphtho pyran, photochromic compounds(s) and/or nonphotochromic coloring agent;    (iii) a (co)polymer matrix which comprises naphtho pyron compound(s), copolymer, reticulate compound and/or photochromic composition;    (iv) an ophthalmic or solar articles; and    (v) a glazing and / or optical device.    M = a metal that reacts with benzophenone;    R1, R2, R3, R4, R5, n, m, p = as above.
