Abstract
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.
