Phthalocyanine compound, that intermediate field, production manner of the said phthalocyanine compound and the color filter which uses this, the phthalocyanine compound which is displayed

摘要

PURPOSE: To obtain the subject new compound having a high solubility and absorption coefficient and capable of providing a color filter excellent in transparency behavior, light resistance and heat resistance by reacting a specific phthalocyanine compound with a metal derivative. ;CONSTITUTION: A compound of formula I {R₁ to R₄ are each formula II [R₅ is an alkyl, an alkoxy, a (substituted) phenyl(oxy) or a benzyl(oxy)]; regarding the positions of R₁ to R₄, R₁ is at C1 or C4, R₂ is at C5 or C8, R₃ is at C9 or C12 and R₄ is at C13 or C16; M is a pair of H atoms, a divalent metal or a metal derivative of a trivalent or tetravalent metal}. Further, the compound is preferably obtained by reacting (A) a phthalonitrile compound of formula III with (B) a metal derivative (e.g. palladium chloride) e.g. in a ratio of the component B: the component A of 1:3 to 1:6 (mol ratio) in the presence of a catalyst such as 1,8-diazabicyclo[5,4,0]-7-undecene in a solvent such as n- aminoalcohol at 130-230°C for 5-15hr.;COPYRIGHT: (C)1996,JPO
