<P>PROBLEM TO BE SOLVED: To provide an ink composition, which is excellent in dispersion stability, redispersibility, and storage stability and by which images with high image quality can be obtained without a blur because of good discharge stability even when the ink composition is applied for various inkjet-recording methods based on a variety of systems. <P>SOLUTION: The ink composition for inkjet comprises resin particles with a grain size of 0.8 μm or more, which are dispersed in (A) a non-aqueous system dispersion medium with the use of (B) a dispersing agent having a basic group. The method for producing a planographic printing plate uses the ink composition for inkjet. The ink composition of the present invention is useful for various methods for producing planographic printing plate by which printed matter on which clear images with high image quality are printed can be obtained with the use of an inkjet-recording method. <P>COPYRIGHT: (C)2008,JPO&INPIT |
