• 論文の詳細を見る

• In order to obtain information concerning the function of the polar group of polymeric dispersants generally used for pigment particles in a non-aqueous medium, alkylamine, alkylammonium salt, amide, and carboxylic acid were selected as the model dispersants and their adsorption behavior onto the phthalocyanine blue (PhB) pigment was studied by means of 1H NMR spin-lattice relaxation time using a high-resolution magic angle spinning 1H NMR probe. The amino group, particularly the primary amino group, was found to be the most effective as the adsorption site for the pigment among the functional groups examined in this study. The results obtained in this work suggest that the coordination of a lone electron pair on the nitrogen atom of an amino group to the Cu(II) of PhB is the driving force for the adsorption.
