An aqueous organic pigment dispersion contains a green copper phthalocyanine pigment and an azo-coupled β-ketoamide pigment. It also includes an organic pigment dispersant at 40 weight % to 100 weight %, based on the sum of the weights of the organic pigments. The weight ratio of the green copper phthalocyanine pigment to the azo-coupled β-ketoamide pigment is from 1:1 to 10:1. The median particle diameter of each of the green copper phthalocyanine pigment and the azo-coupled β-ketoamide pigment is less than 85 nm. At least 95% of the total particles of each of the green copper phthalocyanine pigment and the azo-coupled β-ketoamide pigment have a particle diameter of less than 150 nm. This dispersion can be used to prepare aqueous green inkjet ink compositions that can be used in various inkjet printing methods.

The present invention discloses an oxidation-resistant conductive copper past, a manufacturing method and a use thereof. The oxidation-resistant conductive copper paste comprises 70 wt % to 90 wt % of copper particles, a binder, a thixotropic agent and a solvent. The manufacturing method comprises the steps of mixing the binder, the thixotropic agent and ethanol thoroughly to obtain a first mixture; mixing the solvent with the first mixture thoroughly to obtain a second mixture; mixing the copper particles with the second mixture to obtain a conductive copper paste precursor; and removing the ethanol from the conductive copper paste precursor to obtain the oxidation-resistant conductive copper paste. The oxidation-resistant conductive copper paste can be used for manufacturing a conductive film of a circuit board or an electrode of a solar battery by a printing process.

A nonaqueous inkjet printing method that can provide prints with both high printing density and good gradation is provided. The nonaqueous inkjet printing method comprises printing an image by an inkjet recording system using a first nonaqueous ink comprising at least a coloring pigment, a water-soluble resin having an amino group, and a nonaqueous solvent, and then printing an image so as to overlap with the preceding image by an inkjet recording system using a second nonaqueous ink, wherein the second nonaqueous ink comprises at least a coloring pigment, inorganic particles, and a nonaqueous solvent, and the content of the coloring pigment in the second nonaqueous ink is lower than the content of the coloring pigment in the first nonaqueous ink. The first nonaqueous ink is preferably printed at a higher resolution of printing than the second nonaqueous ink.
