POLYMERIC DISPERSANT FOR LIQUID DEVELOPER, LIQUID DEVELOPER, AND PRINTED MATTER |
| 摘要 |
An embodiment of the present invention relates to a polymeric dispersant for a liquid developer, which is obtained by copolymerizing at least an ethylenically unsaturated monomer having an amino group, an ethylenically unsaturated monomer having an alkyl group with a carbon number of 9 to 24, and an ethylenically unsaturated monomer represented by general formula (1) shown below:;CH2═C(R1)COO(AO)nR2 General formula (1);wherein, R1 represents H or CH3, R2 represents a hydrogen atom or a hydrocarbon group having a carbon number of 1 to 22, n represents an integer of 1 to 200, and A represents an alkylene group having a carbon number of 2 to 4. |

1. A polymeric dispersant for a liquid developer, which is obtained by copolynterizing at least an ethylenically unsaturated monomer having an amino group, an ethylenically unsaturated monomer having an alkyl group with a carbon number of 9 to 24, and an ethylenically unsaturated monomer represented by formula (1) shown below:
CH2═C(R1)COO(AO)nR2 formula (1)wherein
R1 represents H or CH3, R2 represents a hydrogen atom or a hydrocarbon group having a carbon number of 1 to 22, n represents an integer of 1 to 200, and A represents an alkylene group having a carbon number of 2 to 4. |
