Claims15
A method for producing a decorative article, comprising:
- a step of performing inkjet printing onto a surface of a humidity-conditioning base material using an aqueous inkjet ink consisting essentially of water, a water-dispersible resin, a colorant, a surfactant, and a water-soluble organic solvent.
A decorative article, comprising:
- an image formed by inkjet printing on a surface of a humidity-conditioning base material, wherein the image is formed using an aqueous inkjet ink consisting essentially of water, a water-dispersible resin, a colorant, a surfactant, and a water-soluble organic solvent.
A method for producing a decorative article, comprising:
- a step of performing inkjet printing onto a surface of a humidity-conditioning base material using an aqueous inkjet ink containing at least water, a water-dispersible resin, and a colorant, wherein the aqueous inkjet ink consists essentially of water, a water-dispersible resin, a colorant, and a water-soluble organic solvent.
A decorative article comprising:
- an image formed by inkjet printing on a surface of a humidity-conditioning base material, wherein the aqueous inkjet ink consists essentially of water, a water-dispersible resin, a colorant, and a water-soluble organic solvent.
A method for producing a decorative article, comprising:
- a pre-treatment step of applying a pretreatment liquid to a surface of a humidity-conditioning base material, the pretreatment liquid containing at least water, a water-dispersible resin, and fine particles having an average primary particle size of not more than 300 nm;
- and
- a step of performing inkjet printing onto the pre-treated surface of the humidity-conditioning base material using an aqueous inkjet ink containing at least water, a water-dispersible resin, and a colorant,
- wherein the fine particles are composed of a mixture of first fine particles and second fine particles, the first fine particles having an average primary particle size that is equal to or greater than an average primary particle size of the water-dispersible resin contained in the aqueous inkjet ink, and the second fine particles having an average primary particle size that is smaller than an average primary particle size of the water-dispersible resin contained in the aqueous inkjet ink.
