Abstract
(EN)
The present invention provides an aqueous composition for inkjet, which is capable of exhibiting excellent color developability with respect to various recording media; and the present invention also provides a method for producing a recorded matter, which enables the production of a recorded matter that has excellent color developability. An aqueous composition for inkjet according to the present invention contains a dye that is composed of at least one dye selected from among sublimation dyes and disperse dyes, a polyester and water; and the content of the polyester is from 4 to 300 times (inclusive) the content of the dye. It is preferable that the content of the polyester is from 5% by mass to 30% by mass (inclusive). It is preferable that the content of the dye is from 0.1% by mass to 7.5% by mass (inclusive).
