Abstract

A pre-impregnate (I) is prepared by impregnation of a raw paper with a thermally cross-linkable combination (II) comprising a formaldehyde-free resin solution and a polymer dispersion in a mix ratio (solids:solids) of 45:55-10:90 with a residual moisture content of 2-3 wt.% whereby the dried pre-impregnate (I) has a degree of cross-linking of 10-85%. An independent claim is included for a process for the preparation of the preimpregnate (I) by impregnating raw paper with the combination (II) and drying.
