ABSTRACT:
A novel phthalocyanine compound having improved solubility and high purity and containing a polymerizable vinyl group within its molecule is provided. Intermediates to this phthalocyanine compound also have improved solubility and high purity. Further, with the novel phthalocyanine compound used as a starting monomer, a novel polymer is obtained which has a high content of (metal) phthalocyanine and is easy to control the orientation of phthalocyanine rings. The polymer having improved solubility and high purity is expected of use as functional material such as catalysts and recording material.
