Method for manufacturing paper printable with inkjet for use as a decor paper
A method for manufacturing paper or thermoplastic foil printable with an inkjet printer for use as a decor paper, respectively decor foil in a laminate or laminated panel may involve providing a paper layer, respectively a thermoplastic foil. At least one side of the paper layer, respectively the foil may be coated with an inkjet receiver coating that includes pigment and binder. Application of the inkjet receiver coating may involve applying a first layer with a first composition and, subsequently, applying a second layer with a second composition. Both the first and the second compositions may include the binder. Papers and foils may also be obtained. A method of manufacturing panels may involve providing the paper or foil with a printed pattern and used as a decor in the panels.
1. A method for manufacturing paper printable with an inkjet printer for use as a decor paper in a laminate panel, the method comprising:
providing a paper layer; and
coating at least one side of the paper layer with an inkjet receiver coating that includes pigment and binder;
wherein applying the inkjet receiver coating involves applying a first layer with a first composition and, subsequently, applying a second layer with a second composition;
wherein the first and the second compositions include the binder; and
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 and the second layer comprise pigment and binder, but 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:
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 contained in the second layer.
2. The method according to claim 1 , wherein the first composition has a pigment to binder ratio which is larger than the pigment to binder ratio of the second composition.
3. The method according to claim 2 , wherein the pigment to binder ratio in the second composition is lower than 2.
4. The method according to claim 2 , wherein the pigment to binder ratio in the first composition is larger than 3.5.
5. The method according to claim 1 , wherein the pigment is silica particles, and/or the binder is polyvinyl alcohol.
6. The method according to claim 1 , wherein the paper layer has a mean air resistance with a Gurley value of below 30 seconds.
7. A method for manufacturing a laminate panel, wherein the panel at least comprises a substrate material and a provided thereon top layer with a printed decor;
wherein the top layer is substantially formed from thermosetting resin and one or more paper layers;
wherein the paper layers comprise a decor paper on the basis of a paper obtained by the method according to claim 1 .
