Title:
BLACK INK COMPOSITION FOR INKJET PRINTING, AND METHOD FOR PRINTING ON HYDROPHOBIC FIBERS
Document Type and Number:
WIPO Patent Application WO/2020/017432
Kind Code:
A1
Abstract:
Provided is a black ink composition for inkjet printing that contains a water-soluble organic solvent, a dispersing agent, and at least four types of sublimation dyes. The sublimation dyes are selected from the group consisting of C.I. disperse yellow, C.I. disperse red, and C.I. disperse blue, at least one of the sublimation dye types has a maximum absorption wavelength in the wavelength band of 570 nm to 590 nm as measured from the visible spectral absorption of a solution obtained by dissolving said dye in acetone, and at least one other sublimation dye type has a maximum absorption wavelength in the wavelength band of 640 nm to 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.
