Abstract

1. A process for the production of paper exhibiting high wet strenght by adding a melamine-formaldehyde resin colloid to the paper stock and dewatering the paper stock on the paper machine, wherein the melamine-formaldehyde resin colloid used is a product which has been obtained by continuously mixing a 40 to 80% strength aqueous solution of an optionally modified methylol melamine with water and acid in a mixing zone under conditions of turbulent flow at a temperature of from 40 to 110 degrees C and a pH of 2 to 4, the time which elapses between mixing of the components and addition of the mixture to the paper stock being from 1 to 300 seconds, the solids content of the melamine-formaldehyde resin colloid solution being from 5 to 20% by weight.
