Abstract
Abstract A phthalocyanine compound of the Formula (1): ##STR1## wherein: Pc is a phthalocyanine nucleus which is metal free or contains a metal or oxymetal; X is S; NT or O; Y is S; NT or O; Z is S or Se; in which T in the above is H; alkyl or aryl; + HA is an aliphatic polyamino ammonium ion or a substituted diguanidinium ion; each R independently is an aromatic radical linked to a peripheral carbon atom of the Pc nucleus through an atom Z; each R 1 independently is optionally substituted phenylene or naphthylene in which the atoms X and Y are attached to adjacent nuclear carbon atoms in R 1 and to adjacent peripheral carbon atoms of the Pc nucleus; a is 0 to 16; provided that b is 0 to 8; a+b>0; and c+d is 1 to 16.
