An image forming method includes a processing fluid applying step and an ink applying step. The processing fluid applying step involves applying a processing fluid containing a multivalent metal salt, a resin T.sub.A, a resin T.sub.B different from the resin T.sub.A, and a silicone-based surfactant to a non-permeating base material by an inkjet method, where the processing fluid is free of an organic solvent having a boiling point of 200° C. or higher at normal pressure. The ink applying step involves applying an ink containing a coloring material, an organic solvent, and a resin onto the processing fluid.

A printed textile includes a base textile and a layer. The base textile includes first and second surfaces. The first surface includes a first area and a second area. The layer is located on the first surface, and contains pigment particles. A first loop height is defined as a largest height of the printed textile when the printed textile is folded with a crease at the first area. A second loop height is defined as a largest height of the printed textile when the printed textile is folded with a crease at the second area. The second loop height is no more than 1.3 times as large as the first loop height.

The present invention relates to [1] an aqueous composition for ink-jet printing containing a carbodiimide compound, a vinyl polymer and water, in which the vinyl polymer is dispersed in the aqueous composition in the form of polymer particles formed by partially neutralizing carboxy groups of the vinyl polymer with a basic compound having a boiling point of not higher than 130° C.; [2] an ink set for ink-jet printing containing an aqueous composition a containing a carbodiimide compound and water, and an aqueous composition b containing a vinyl polymer; and [3] an ink-jet printing method including the step 1 of ejecting a carbodiimide compound, a pigment, a vinyl polymer and water by an ink-jetting method to print characters or images, and the step 2 of subjecting the resulting printed characters or images to heat treatment at a temperature of 50 to 200° C. According to the aqueous composition of the present invention, it is possible to obtain a printed material that is excellent in rub fatness.
