Title:
INK SET AND INKJET RECORDING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/151412
Kind Code:
A1
Abstract:
One embodiment of the present invention provides an ink set and application thereof. The ink set contains at least an ink containing a compound represented by general formula (Y-1) or (Y-2) and so forth; an ink containing general formula (MM) or a compound represented by general formula (M) and so forth; an ink containing a compound represented by general formula (C) and so forth; and an ink containing a compound represented by general formula (B) and so forth. Each ink composition contains, with reference to the total mass of each ink composition, 0.5% to 5.0% of an N-free solvent A having an SP value of 22 to 26 MPa1/2, 0.1% to 5.0% of an N-containing solvent B having an SP value of 24 to 29 MPa1/2, 10% to 50% of an N-free solvent C having an SP value of 29 to 31 MPa1/2, 5% to 30% of an N-free solvent D having an SP value of 32 to 34 MPa1/2, and 30% to 60% of water. The ratio of the total mass of Li with reference to the total mass of alkali metal, that are contained in the overall ink provided by mixing the individual ink compositions in an equal mass ratio, is at least 70%.
