Abstract
Abstract A phthalocyanine compound of the formula: wherein Pc is a phthalocyanine nucleus; each R independently is optionally substituted phenyl; m is 4 to 12; V is H or C₁₋₄-alkyl; each R¹ independently is optionally substituted phenylene or naphthylene in which the S atom and group N-C are attached to adjacent nuclear carbon atoms; and n is 2 to 6; provided that R is not R¹-NHV. The compounds have a significant absorption band in the near infra red and are soluble in non-polar organic media. The compounds are useful in many applications where absorption of infra-red radiation is desirable, such as in OCR readable inks, security printing and reprographic toners.
