Abstract:
The object of the present invention is to provide an ink composition that is excellent in terms of adhesion to a recording medium, for which there is little leaching out (migration) of a component in the cured ink film, and that gives a printed material with suppressed odor, and an inkjet recording method and a printed material employing the ink composition, and also to provide a novel acylphosphine oxide compound. The ink composition of the present invention contains an acylphosphine oxide compound having an acyl group comprising a polymerizable functional group, and a polymerizable compound.
Abstract:
A decorative sheet includes a resin substrate, and an image layer that includes a fixed-ink image formed of an ink composition containing (a) a pigment, (b) polymer particles, (c) a water-soluble organic solvent, and (d) water, on the resin substrate. When a tensile test is performed on the decorative sheet in an atmosphere at 180° C., a stretching rate thereof that is defined as below is 150% or higher. Stretching rate (%)=[(length at the time of breakage−length before stretching)/(length before stretching)]×100
Abstract:
An inkjet ink composition includes: (a) particles of a polymer compound having at least one reactive functional group selected from the group consisting of an epoxy group, an acetoacetoxy group, a halomethyl group, a carboxylic acid anhydride, an amino group, a hydroxyl group, a phenolic hydroxyl group, and a carboxy group; (b) a reactive compound having a functional group that reacts with the reactive functional group of the (a) particles of the polymer compound by energy application; (c) a coloring agent; and (d) a water-soluble organic solvent.
