NEW MATERIAL:A compound of formula I [at least one of R<1>-R<8> is -CH2CH (OH)CH2OR<9> (R<9> is H, 1-18C alkyl, 1-18C alkenyl or 6-20C aryl), the rest being H]. USE:Useful in such fields as optical recording and electrophotograhic technologies. Giving marked adsorptions in the near-infrared region, and having high dissolvability. PREPARATION:For example, a ring opening addition reaction, at room temperature-250 deg.C in general, of a monoglycidyl compound of formula II (e.g., alycidol, butyl glycidyl ether) to a tetraminovanadyl phthalocyanine is carried out, in the presence of an addition reaction catalyst such as Lewis acid if needed, using an inert solvent depending on circumstances. |
