AQUEOUS INK, INK TANK, INKJET RECORDER, INKJET RECORDING METHOD, AND INKJET RECORDED IMAGE

摘要

Disclosed is an aqueous ink characterized by containing a dispersible colorant comprising a colorant (1) and chargeable resin pseudo fine particles (2) having a smaller size than the colorant, which colorant and chargeable resin pseudo fine particles are fixed to each other, and at least one of a water-soluble nonionic resin (15-1) and emulsion particles (16-1). Consequently, there can be obtained an aqueous ink having high dispersion stability and excellent long-term dispersion stability which is suitable for inkjet recording and enables to obtain an image having excellent fastness such as abrasion resistance, in particular an image having excellent glossiness. Also disclosed are an ink tank, inkjet recorder, inkjet recording method and inkjet recorded image using such an aqueous ink.
