Inkjet printing methods for manufacturing of decorative surfaces
View Patent ↗An inkjet printing method for manufacturing decorative surfaces includes the steps of a) jetting a color pattern with one or more aqueous inkjet inks including a polymer latex binder on a thermosetting resin impregnated paper; and b) drying the one or more aqueous inkjet inks.
1. An inkjet printing method for manufacturing decorative surfaces, the method comprising the steps of:
jetting a color pattern with one or more aqueous inkjet inks including a polymer latex binder onto a thermosetting resin impregnated paper; and
drying the one or more aqueous inkjet inks; wherein
the color pattern includes less than 6 g/m 2 ink dry weight.
2. The inkjet printing method according to claim 1 , wherein the one or more aqueous inkjet inks include an aqueous inkjet ink including a color pigment selected from the group consisting of C.I. Pigment Yellow 151, C.I. Pigment Yellow 74, and mixed crystals thereof.
3. The inkjet printing method according to claim 1 , wherein the one or more aqueous inkjet inks include an aqueous inkjet ink including a color pigment selected from the group consisting of C.I. Pigment Red 254, C.I. Pigment Red 122, and mixed crystals thereof.
4. The inkjet printing method according to claim 1 , wherein the one or more aqueous inkjet inks define an aqueous inkjet ink set including:
a cyan aqueous inkjet ink including a copper phthalocyanine pigment;
a red aqueous inkjet ink including a color pigment selected from the group consisting of C.I. Pigment Red 254, C.I. Pigment Red 122, and mixed crystals thereof;
a yellow aqueous inkjet ink including a color pigment selected from the group consisting of C.I. Pigment Yellow 151, C.I. Pigment Yellow 74, and mixed crystals thereof; and
a black aqueous inkjet ink including a carbon black pigment.
5. The inkjet printing method according to claim 1 , wherein the thermosetting resin is a melamine based resin.
6. The inkjet printing method according to claim 1 , wherein the polymer latex binder is a polyurethane based latex binder.
7. The inkjet printing method according to claim 1 , wherein the one or more aqueous inkjet inks are jetted at a temperature of not more than 35° C.
8. The inkjet printing method according to claim 1 , wherein the thermosetting resin impregnated paper includes a colored paper substrate.
9. The inkjet printing method according to claim 1 , wherein the step of jetting the color pattern is performed using a single pass printing process.
10. The inkjet printing method according to claim 1 , wherein the one or more aqueous inkjet inks include a humectant in an amount from 0.1 to 30 wt % based on a total weight of the aqueous inkjet ink.
