Abstract
Copper and nickel 1,8 binaphthalocyanines were prepared by the urea fusion method. The proposed structure of these compounds was confirmed via micro‐analytical, volumetric and spectrophotometry methods. The prepared binaphthalocyanines compounds showed excellent pigmentary properties on evaluating them according to specific international standard methods.
