Title:
BLACK INK COMPOSITION FOR INKJET PRINTING, AND METHOD FOR PRINTING ON HYDROPHOBIC FIBERS
Document Type and Number:
WIPO Patent Application WO/2020/017430
Kind Code:
A1
Abstract:
Provided is a black ink composition for inkjet printing that contains a water-soluble organic solvent, a resin emulsion, a dispersing agent, and at least four types of sublimation dyes. At least three of the sublimation dye types are selected from the group consisting of C.I. disperse yellow, C.I. disperse red, and C.I. disperse blue, and at least one of the sublimation dye types has a maximum absorption wavelength in the wavelength band of 640 nm to less than 680 nm as measured from the visible spectral absorption of a solution obtained by dissolving said dye in acetone. Also provided are an ink set for inkjet printing that comprises the black ink composition for inkjet printing, and a method for printing on hydrophobic fibers that uses the composition and the ink set.
