Isomer mixts. of alpha-alkoxy-substd. phthalocyanines (I) of formulae (IA-D) or beta-alkoxy-substd. phthalocyanines (II) of formulae (IIA-D), which contain at least 80 % (IB) and (IIB) and (IIC) and at most 20 % (ID) or (IID) and have a ratio of (IB) or (IIB) to (IC) or (IIC) of (0.3-3.0):1, are claimed. In the formulae, Me = a divalent metal atom or divalent oxo-metal; R1 = 1-16 C alkyl, 3-16 C alkenyl or 3-16 C alkynyl, opt. substd. by 1-12 C alkoxy, CN, NO2, halogen, OH, Ph, cyanophenyl, nitrophenyl, halophenyl, hydroxy-phenyl or (1-12 C alkoxy)phenyl. Also claimed are a method for the prepn. of the mixts., and a material for optical information recording and storage, which has layer(s) of (I) or (II) on a transparent dielectric substrate. Me = Fe(II), Ru(II), Rh(II), Pt(II), Mn(II), Mg(II), Be(II), Ca(II), Ba(II), Cd(II), Hg(II), VO, MnO, TiO, esp. Zn(II), Sn(II), Ni(II), Co(II), Pb(II) or more esp. Cu(II) or Pd(II); R1 = substd. or esp. unsubstd. 1-16 C alkyl. The mixts. contain at least 90, esp. at least 95 %, (IB) and (IC) or (IIB) and (IIC) and at most 10 %, esp. at most 5 %, (IA) and (ID) or (IIA) and (IID). |
