14. A method for producing a laminate panel, wherein the method comprises the following steps:

providing a carrier layer;

providing a décor at least on the top surface of the carrier layer;

applying of resin onto the top surface of the carrier layer in liquid state;

applying a counteracting material that does not comprise a paper layer onto the back surface of the carrier layer in liquid state;

in a subsequent method step curing the resin and the counteracting material; and

after or during the curing of resin and the counteracting material, pressing the layers that are produced in the previous method steps to form a laminate panel; and

wherein prior to the application of the counteracting material onto to the back surface of the carrier layer, the amino resin of the counteracting material is produced by mixing of (i) melamine and/or an urea derivate and (ii) an aldehyde, wherein for producing the amino resin 1 mol of melamine and/or urea derivate is mixed with 0.5 to 3 mol of aldehyde.

15. The method according to claim 14 , wherein the resin of the top surface of the laminate panel and the counteracting layer on the back surface of the laminate panel are cured essentially simultaneously.

16. The method according to claim 14 , wherein the application of the counteracting material is made in a roller-coating process or by spraying or applying by jet nozzles.
