Title:
ACRYLIC RESIN EMULSION FOR WATER-BASED INKJET INKS, AND WATER-BASED INKJET INK COMPOSITION PRODUCED USING SAME
Document Type and Number:
WIPO Patent Application WO/2014/104319
Kind Code:
A1
Abstract:
[Problem] For the purpose of obtaining a water-based inkjet ink composition which can exhibit a high viscosity without requiring the use of a thickening agent and has excellent ink properties including glossiness, an acrylic resin emulsion for water-based inkjet inks is provided. The acrylic resin emulsion contains acrylic resin particles having an acid value of 1 to 100 mgKOH/g, wherein the ratio of the molar content ratio (As) of an acid-group-containing monomer in the surface regions of the acrylic resin particles to the molar content ratio (At) of the acid-group-containing monomer in the whole bodies of the acrylic resin particles (i.e., (As/At)) as measured at a 1H spin diffusion time of 5 ms is 9 or more.
