水素結合を形成する。[Example 1 As shown in FIG. 1, the non-polar main chain 101 indicated by the solid line
encloses the entire coloring material 102 and dissolves it in the dispersion solvent 103 shown in thin black. Further, the side chain 104 having a polar group shown by a dashed line is oriented to the coloring material which also has a polar group to form a hydrogen bond.

り、プリンタノズル詰まりが発生しにくい。FIG. 2 shows changes on the paper 201 after the main ink has been ejected and recorded. The coloring material is bolded on the side chain even after printing,
Even when the solvent around the coloring material flows, it cannot carry the coloring material, so there is almost no bleeding of printed dots onto the paper, and clear printing can be obtained. Further, since the dispersion solvent is held between the coloring material and the polymer and the solvent is surrounded by the main chain, printer nozzle clogging is less likely to occur.

Not only does it greatly improve the printing characteristics during high-temperature storage, but it also has the effect of preventing bleeding by holding the recording dots in the polymer and allowing high print recording. Furthermore, the cohesive force and adhesive force of the bomber have the effect of making it possible to print on a variety of transfer papers, such as plastics such as torrence bailancy, and on metal surfaces.
