Hydrophilization of guaiazulene-based blue pigment: improving its stability in acidic conditions by substitution with polyallylamine
By condensing guaiazulene carboxylic acid with poly(allylamine), guaiazulene-substituted poly(allylamine) was synthesized. The polymer showed high water solubility and improved stability even under acidic conditions.
