DISPERSING AGENT OR SOLUBILIZING AGENT CONTAINING CALIXARENE COMPOUND

摘要

A dispersing agent or solubilizing agent characterized by containing a specific calixarene compound in which among the phenolic hydroxy groups at least one remains unreplaced and at least one has been replaced with a group having a total carbon number of 10 or larger which comprises a group consisting of one or more alkyleneoxy groups and/or a hydrocarbon group. With this dispersing or solubilizing agent, a carbonaceous material (e.g., a fullerene or carbon nanotubes), an organic pigment (e.g., phthalocyanine blue), etc. can be dispersed or dissolved in organic matrixes (e.g., organic solvents) to a higher degree than in conventional techniques.
