<p>PURPOSE:To improve the microscopic dispersibility and dispersion stability of pigment particles by adding a pigment, a specified dispersant and a dispersion stabilizer to a vehicle mainly composed of ethanol. CONSTITUTION:1 to 15wt.% pigment (e.g. carbon black) and 0.1 to 10wt.% carboxylated polyoxyalkylene alkyl ether (derivative) of the formula (wherein R1 is an 8-36C alkyl; R2 is a 2-4C alkylene; n is 1-30; M is H, metal atom such as Na or K, ammonium or alkanolamine) is dispersed or dissolved in a vehicle containing 50wt.% or more ethanol.</p> |
