Phthalocyanine formulation and uses thereof
The present invention provides a chemiluminescent ink formulation, comprising: a phthalocyanine metal catalyst; a visible dye; and a solvent. The formulation is useful in catalyzing a chemiluminescent reaction, by admixing for example, luminol or isoluminol with an oxidizing agent, a base and the chemiluminescent ink formulation to emit light.
