Abstract
The invention provides an ink composition including a pigment, water, a polymerizable compound having an acrylamide structure, a polymerization initiator and a wetting agent that is in the form of a solid at a temperature of 25° C. and an atmospheric pressure of 1 bar, the wetting agent being included in the ink composition in an amount of from 0.01% by mass to 400% by mass with respect to the polymerizable compound having an acrylamide structure.
Claims14
An ink composition comprising a pigment, water, a polymerizable compound having an acrylamide structure, a polymerization initiator and a wetting agent that is in the form of a solid at a temperature of 25° C. and an atmospheric pressure of 1 bar,
- the wetting agent being included in the ink composition in an amount of from 0.01% by mass to 400% by mass with respect to the polymerizable compound having an acrylamide structure.
An image forming process comprising:
- applying a treatment liquid, which aggregates an ink composition, onto a recording medium;
- and
- applying the ink composition by inkjetting onto the recording medium to form an image,
- the ink composition comprising a pigment, water, a polymerizable compound having an acrylamide structure, a polymerization initiator and a wetting agent that is in the form of a solid at a temperature of 25° C. and an atmospheric pressure of 1 bar,
- the wetting agent being included in the ink composition at a proportion of from 0.01% by mass to 400% by mass with respect to the polymerizable compound having an acrylamide structure.
