Method for manufacturing paper printable with inkjet for use as a decor paper
A paper for inkjet printing may have one side that is provided with an inkjet receiver coating. The inkjet receiver coating may comprise at least pigment and binder. A portion of free or unbound pigment may be less than 10 weight percent of the total amount of pigment in the inkjet receiver coating and/or the inkjet receiver coating may have a surface that is substantially free of pigment.
1. A paper for inkjet printing, wherein the paper at least at one side is provided with an inkjet receiver coating comprising at least pigment and binder; and
wherein a portion of free or unbound pigment is less than 10 weight percent of the total amount of pigment in the inkjet receiver coating and/or wherein the inkjet receiver coating has a surface that is substantially free of pigment.
2. The paper according to claim 1 , wherein the inkjet receiver coating comprises a first layer with a first composition and a second layer with a second composition; and
wherein the first and the second compositions include the binder.
3. The paper according to claim 2 , wherein the first layer and the second layer differ in that they show one or more of the following properties:
the property that the first layer as well as the second layer comprise pigment and binder in a different pigment to binder ratio;
the property that the dry weight of material applied for the first layer and the second layer is different; and
the property that the first layer and the second layer comprise pigment and binder, wherein the average particle size of the pigments contained in the first layer is larger than the average particle size of the pigments contained in the second layer.
4. The paper according to claim 3 , wherein the first composition has a pigment to binder ratio that is larger than the pigment to binder ratio of the second composition.
5. The paper according to claim 4 , wherein the pigment to binder ratio in the second composition is less than 2.
6. The paper according to claim 5 , wherein the pigment to binder ratio in the first composition is greater than 3.5.
7. The paper according to claim 1 , wherein the pigment is silica particles, and/or the binder is polyvinyl alcohol.
8. The paper according to claim 1 , wherein the paper has a Gurley value of between 60 and 120 seconds.
9. A method for manufacturing a laminate panel, wherein the panel comprises a substrate material and provided thereon a top layer with a printed decor;
wherein the top layer is substantially formed from a thermosetting resin and one or more paper layers; and
wherein the paper layers include a decor paper on the basis of a paper for inkjet printing according to claim 1 .
10. The method according to claim 9 , wherein the paper for inkjet printing is printed using an inkjet printer, is impregnated with an amount of the thermosetting resin, and is attached to the substrate material via a hot pressing treatment.
11. The method of claim 10 , wherein the inkjet printer operates using water-based inks.
12. The method of claim 10 , wherein the inkjet printer is of the single-pass type and/or is operated in single-pass mode.
13. The method of claim 10 , wherein the inkjet printer operates using pigment containing inks.
14. A paper for inkjet printing, wherein the paper at least at one side is provided with an inkjet receiver coating comprising at least pigment and binder; and
wherein the inkjet receiver coating has a surface that is substantially formed by the binder.
