The pigment preferably has a uniform particle size. By carrying out the dispersion treatment by incorporating the pigment dispersant, a pigment dispersion liquid in which the pigment is uniformly dispersed in the solution can be obtained.
　前記の顔料分散剤としては、例えば、カチオン系、アニオン系、ノニオン系、両性、ポリエステル系、ポリアミン系、アクリル系等の界面活性剤が挙げられる。これらの顔料分散剤は、単独でも２種以上を組み合わせて用いてもよい。顔料分散剤としては、商品名でＫＰ（信越化学工業（株）製）、フローレン（共栄社化学（株）製）、ソルスパース（ゼネカ（株）製）、ＥＦＫＡ（ＣＩＢＡ社製）、アジスパー（味の素ファインテクノ（株）製）、Ｄｉｓｐｅｒｂｙｋ（ビックケミー社製）などが挙げられる。 Examples of the pigment dispersant include cationic, anionic, nonionic, amphoteric, polyester, polyamine, and acrylic surfactants.
