Abstract

An aqueous inkjet ink set for manufacturing decorative panels comprising: a) a cyan aqueous inkjet ink containing a beta-copper phthalocyanine pigment; b) a red aqueous inkjet ink containing a red pigment R and a polymeric dispersant P; c) a yellow aqueous inkjet ink containing a yellow pigment; and d) a black aqueous inkjet ink containing a carbon black pigment; wherein the red aqueous inkjet ink has a weight ratio R/P of red pigment R to polymeric dispersant P that complies with 1.2 < R/P < 3.0; and wherein the average particle diameter APD of the red pigment R complies with 175 nm < APD < 240 nm, as determined by a dynamic light scattering technique using a laser having an emission wavelength of 633 nm and measured under a scattering angle of 90 degrees.
