Abstract
The invention relates to an anti-bacterial additive for melamine resins, in particular for melamine-formaldehyde or melamine-urea-formaldehyde resins. The additive has at least one borate salt and a quaternary ammonium compound as the anti-bacterial active ingredients. As a result of the small number of individual constituents, said additive can be easily incorporated into the melamine resin, is extremely compatible with the latter and has an effective, long-lasting anti-bacterial action.
