<P>PROBLEM TO BE SOLVED: To provide an ink composition which provides a printed mater having suppressed odor and is excellent in curability, in particular, exhibits curability when formed into a thin film, and is excellent in blocking resistance, and which is also excellent in dispersion stability, and to provide a method for forming an image. <P>SOLUTION: The ink composition contains (a) a pigment, (b) a polymer having a repeating unit represented by general formula (1), (c) a polymerizable compound, and (d) a benzophenone derivative. In the general formula (1), R<SP POS="POST">a1</SP>represents hydrogen atom or methyl group; A represents -COO-, -CONR<SP POS="POST">a4</SP>- or phenylene group, wherein R<SP POS="POST">a4</SP>represents hydrogen atom or methyl group; B<SP POS="POST">1</SP>represents 1-10C alkylene group; T is a single bond, -O- or -NR<SP POS="POST">a5</SP>-, wherein R<SP POS="POST">a5</SP>represents hydrogen atom or methyl group; and R<SP POS="POST">a2</SP>and R<SP POS="POST">a3</SP>each independently represent alkyl group and may be linked to each other to form a ring. <P>COPYRIGHT: (C)2012,JPO&INPIT |
