Dyes of the formulaCuPc--CH.sub.2 --N.sup..sym. (CH.sub.3).sub.3 Cl.sup..crclbar.).sub.n,whereinCuPc is copper phthalocyanine, andn is 2 or 3,and mixtures thereof, are useful as paper dyes. The dyes may be added to paper stock prior to sheet formation or applied to paper in sheet form to produce turquoise colored paper. The dyed or printed paper is bleachable but has good fastness to light, wet treatments, alcohol and soap. The dyes are very soluble in water and exhaust well on, i.e., exhibit good substantivity to, paper.

The present invention relates to a series of novel phthalocyanine compositions (or compounds) suitable for use as photosensitizers for photodynamic therapy. Specifically, the invention relates to a series of new aluminum (Al) germanium (Ge), gallium (Ga), tin (Sn) and/or silicon (Si) phthalocyanines having substituted amine or quaternary ammonium axial ligands attached to the central metal, and the use of these new phthalocyanine compositions for the treatment of cancer through photosensitization. Moreover, the present invention is directed to the methods of preparing these compositions for use in photodynamic therapy.
