Ink set and image printing method
An ink set includes a first ink that contains a white material and a first resin; and a second ink that contains a color material other than the white material and a second resin, wherein the first resin includes a component (A) causing cracks when resin of 0.5 g is dropped onto a slide glass and is dried at a temperature of 50° C. and a humidity of 0% RH for 10 minutes, and wherein the second resin includes a component (B) of at least one of polyolefin wax and ethylene vinyl acetate resin.
1. An inkjet recording method comprising ejecting droplets of an ink composition and depositing the droplets to a recording medium, wherein a first ink that contains a white material and a first resin; a second ink that contains a color material other than the white material; and a third ink that does not contain a color material and contains a second resin, wherein the first resin includes a component (A) of at least one of fluorene resin and styrene acryl resin, and wherein the second resin includes a component (B) of at least one of polyolefin wax and ethylene vinyl acetate resin, wherein an average particle diameter of the color material is smaller than an average particle diameter of the white material, and wherein a ratio (TWB/TWA) of a total amount (TWA) of the component (A) on the printing medium and a total amount (TWB) of the component (B) on the printing medium is equal to or higher than 0.2 and equal to or lower than 1; wherein the white ink and the clear ink are ejected substantially at the same time such that the droplets of the white ink and the droplets of the clear ink are caused to come into contact with and attach onto a printing medium, and then ejecting liquid droplets of color ink so as to attach the liquid droplets onto the liquid droplets of the white ink and the liquid droplets of the clear ink attached to the printing medium.
2. The inkjet recording method according to claim 1 , wherein a content of the second resin in the third ink is equal to or more than 3 mass % and equal to less than 10 mass % in term of solid content.
3. The inkjet recording method according to claim 1 , wherein the component (B) includes the polyolefin wax, and an average particle diameter of the polyolefin wax is equal to or more than 100 nm and equal to or less than 200 nm.
4. An inkjet recording method comprising ejecting droplets of an ink composition and depositing the droplets to a recording medium, wherein a first ink that contains a white material and a first resin; a second ink that contains a color material other than the white material; and a third ink that does not contain a color material and contains a second resin, wherein the first resin includes a component (A) of at least one of fluorene resin and styrene acryl resin, and wherein the second resin includes a component (B) of at least one of polyolefin wax and ethylene vinyl acetate resin, wherein an average particle diameter of the color material is smaller than an average particle diameter of the white material, and wherein a ratio (TWB/TWA) of a total amount (TWA) of the component (A) on the printing medium and a total amount (TWB) of the component (B) on the printing medium is equal to or higher than 0.2 and equal to or lower than 1; wherein the white ink is ejected to attach the liquid droplets of the white ink to a printing medium, and then ejecting liquid droplets of clear ink and liquid droplets of color ink substantially at the same time such that the liquid droplets of the clear ink and the droplets of the color ink are caused to come into contact with and attach onto the liquid droplets of the white ink attached to the printing medium.
5. The inkjet recording method according to claim 4 , wherein a content of the second resin in the third ink is equal to or more than 3 mass % and equal to less than 10 mass % in term of solid content.
6. The inkjet recording method according to claim 4 , wherein the component (B) includes the polyolefin wax, and an average particle diameter of the polyolefin wax is equal to or more than 100 nm and equal to or less than 200 nm.
7. An inkjet recording method comprising ejecting droplets of an ink composition and depositing the droplets to a recording medium, wherein a first ink that contains a white material and a first resin; a second ink that contains a color material other than the white material; and a third ink that does not contain a color material and contains a second resin, wherein the first resin includes a component (A) of at least one of fluorene resin and styrene acryl resin, and wherein the second resin includes a component (B) of at least one of polyolefin wax and ethylene vinyl acetate resin, wherein an average particle diameter of the color material is smaller than an average particle diameter of the white material, and wherein a ratio (TWB/TWA) of a total amount (TWA) of the component (A) on the printing medium and a total amount (TWB) of the component (B) on the printing medium is equal to or higher than 0.2 and equal to or lower than 1; wherein the white ink is ejected to attach the liquid droplets to the printing medium, a process of ejecting liquid droplets of the clear ink so as to attach the liquid droplets onto the liquid droplets of the white ink attached to the printing medium, and a process of ejecting liquid droplets of the color ink to attach the liquid droplets onto the liquid droplets of the clear ink.
8. The inkjet recording method according to claim 7 , wherein a content of the second resin in the third ink is equal to or more than 3 mass % and equal to less than 10 mass % in term of solid content.
