Pre-impregnate obtainable by impregnating a decorative base paper with an impregnating resin solution, characterized in that the impregnating resin solution contains at least one polymer latex and at least one modified starch having a specific molecular weight distribution, the molecular weight of the starch molecules being distributed as follows: - at most 6% by weight of molecules with a molecular weight of 0 to 1000 g / mol, - 5 to 20 wt .-% molecules having a molecular weight of 1,000 to 5,000 g / mol, - 20 to 40 wt .-% molecules having a molecular weight of 5,000 to 25,000 g / mol From 20 to 45% by weight of molecules having a molecular weight of from 25,000 to 200,000 g / mol, from 5 to 22% by weight of molecules having a molecular weight of from 200,000 to 1,000,000 g / mol, from 0.5 to 5% by weight .-% molecules with a molecular weight of more than 1,000,000 g / mol. |
