Description
本発明者らは、上記課題点を解決すべく鋭意検討した結果、以下の発明によって解決できることを見出した。
すなわち、本発明は、顔料、顔料を分散させる分散剤、水溶性有機溶剤および水を少なくとも含有するインクにおいて、
分散剤として
ａ）１種以上のビニルエーテル類から構成された疎水性ブロックと１種以上のビニルエーテル類から構成された親水性ブロックとからなるブロック共重合体と
ｂ）オキシエチレン基を有するノニオン性界面活性剤と
を少なくとも含有し、前記顔料が、前記ブロック共重合体と前記ノニオン性界面活性剤とにより分散されていることを特徴とするインクを提供する。
As a result of intensive studies to solve the above problems, the present inventors have found that the following problems can be solved.
That is, the present invention relates to an ink containing at least a pigment, a dispersant for dispersing the pigment, a water-soluble organic solvent, and water.
As a dispersant, a) a block copolymer comprising a hydrophobic block composed of one or more vinyl ethers and a hydrophilic block composed of one or more vinyl ethers, and b) a nonionic interface having an oxyethylene group an active agent containing at least the pigment, to provide an ink which is characterized that you have been dispersed by said block copolymer and said nonionic surfactant.
