Abstract

The invention relates to watery resin dispersions, a process for their manufacture, and a product. To make available resin dispersions that do not pollute the environment during their processing, while simultaneously generating products that have a high glass transition temperature, it is suggested that the watery resin dispersion contain at least components (I), (II) and (III), whereby R1: unsubstituted single or polynuclear aromatic rest or with amino groups and/or cyano groups and/or nitrile groups and/or with saturated and/or unsaturated aliphatic C2 to C12 carbon chains substituted single or polynuclear aromatic rests R2, R3 and R4: hydrogen, alkyl residue group with up to 15 C atoms or aromatic rest whereby R2, R3 and R4 can be equal to or different from each other, (II) is a co-dispersion agent based on epoxide resins and/or novolak resins and (II) one surfactant.
