Title:
NON-ASSOCIATIVE PHTHALOCYANINE BASED NEAR INFRARED COLORING MATTER AND THIN FILM COMPRISING THE SAME
Document Type and Number:
WIPO Patent Application WO/2003/106567
Kind Code:
A1
Abstract:
A coloring matter comprising a salt of a dihalogen alkylphthalocyanato antimony(V) complex having a benzene ring substituted with an alkyl. The coloring matter has good solubility in an organic solvent, and thus is easy to form a film. Further, the salt does not undergo the association of the molecule thereof even in the form of a film which widens the absorption band thereof, which leads to the formation of a film exhibiting satisfactory strength of the absorption.
