1. A method for producing a recorded matter having a three-dimensional image, comprising the steps of:
applying, to a recording medium including a substrate and a foaming layer provided on the substrate and containing a binder resin and a foaming particle which is foamed by heat, a foam-promoting liquid containing water and a foam-promoting component which lowers a foaming start temperature of the foaming particle such that the foaming particle at a first position of the recording medium is reacted with the foam-promoting component while the foaming particle at a second position of the recording medium is not reacted with the foam-promoting component; and
heating the foaming layer of the recording medium to form a three-dimensional image by promoting foaming of the foaming particle reacted with the foam-promoting component at the first position of the recording medium to which the foam-promoting liquid has been applied while suppressing foaming of the foaming particle unreacted with the foam-promoting component at the second position of the recording medium to which the foam-promoting liquid has not been applied,
wherein the foaming particle includes: a shell layer containing a thermoplastic resin; and a volatile material encapsulated in the shell layer,
wherein the binder resin contains a water-insoluble resin,
wherein the foam-promoting component contains a compound having no hydroxyl group, and
wherein a temperature at which the foaming layer of the recording medium to which the foam-promoting liquid has been applied is heated is equal to or more than the foaming start temperature of the foaming particle reacted with the foam-promoting component and less than a maximum foaming temperature of the foaming particle unreacted with the foam-promoting component.
