<p>PURPOSE:To prepare the title compsn. which allows a colorant to be dispersed well and gives a light-resistant colored thin film excellent in resolving power by dispersing the colorant in an aq. acid or alkali soln. of an ionic resin using a surfactant and mixing the dispersion with a specific light stabilizer. CONSTITUTION:A colorant is dispersed, using an ionic surfactant, in an ionic resin (in terms of transparency, color properties, etc., a pref. anionic resin is an acrylic resin and/or a polyester, and a pref. cationic resin is an acrylic resin and/or an epoxy resin) dissolved in an aq. acid or alkali soln. The resulting dispersion is mixed with a light stabilizer comprising a quenching agent, a hindered amine compd. (e.g. 4-benzoyloxy-2,2,6,6-tetramethylpiperidine) and an antioxidant (e.g. 2,6-di-tert. butyl-4-methylphenol) to give the title compsn., which is excellent in colorability and gives a light-resistant colored thin film excellent in resolving power.</p> |
