Patent ID: 8349464

Claim:
A prepreg obtained by impregnating a decorative base paper with an impregnating resin solution, wherein the impregnating resin solution comprises at least one polymer latex and at least one modified starch with a specific molecular weight distribution, wherein the molecular weight of the starch molecules is: (a) at most 6% by weight of molecules with a molecular weight of 0 to 1,000 g/mol; (b) 5% to 20% by weight of molecules with a molecular weight of 1,000 to 5,000 g/mol; (c) 20% to 40% by weight of molecules with a molecular weight of 5,000 to 25,000 g/mol; (d) 20% to 45% by weight of molecules with a molecular weight of 25,000 to 200,000 g/mol; (e) 5% to 22% by weight of molecules with a molecular weight of 200,000 to 1,000,000 g/mol; (f) 0.5% to 5% by weight of molecules with a molecular weight of more than 1,000,000 g/mol.
