<P>PROBLEM TO BE SOLVED: To provide a coloring composition used for a relief reversal offset method which is little of coating unevenness and little causes shape changes in continuous printing. <P>SOLUTION: The coloring composition is used for the relief reversal offset printing method comprising the coating surface forming step wherein the coloring composition is coated on a releasing surface consisting of a silicone rubber to form a coating surface, the drying step for semi-drying the above coating surface, the removal step wherein a relief printing plate having a predetermined profile is pressed against the above coating surface and the coloring composition is transferred to the convex parts of the relief printing plate before it is removed, and the transfer step for transferring the coloring composition remaining on the coating surface to the base material. The coloring composition contains an organic solvent, which has a boiling point of ≥110°C at 760 mmHg and the coefficient of cubic expansion of the releasing surface by which is ≥0% and ≤50%, coloring matter, and a support for the coloring matter. <P>COPYRIGHT: (C)2007,JPO&INPIT |
