摘要： The present invention provides an anti-curl agent containing an amide compound of specific structure and molecular weight, an ink jet ink containing the amide compound, a method for ink jet recording to form images by ejecting the ink, and a method for reducing curl of recording media using the ink. The anti-curl agent of the present invention can reduce shape changes of a printed paper with a lapse of time, i.e., the curl phenomenon, tending to occur in particular with a plain paper printed over the entire surface, without deteriorating image quality.

摘要： The present invention provides a dispersible colorant having a sufficiently high dispersion stability with a high functional group density on the surface and a resin component present on the surface, the resin component not separating from the surface, and a method for simply producing the same. The present invention also provides an aqueous ink containing the excellent, dispersible colorant, ink tank, ink jet recorder, ink jet recording method and inkjet recorded images. The dispersible colorant comprises a colorant and chargeable resin pseudo fine particles having a smaller size than the colorant, and the colorant and particles are fixed to each other.
