Abstract

The present invention relates to a process for preparing paper or cardboard by adding to the pulp of cellulosic fibres starch particles comprising starch and a coagulating agent wherein the particles have a particle size of from 20 to 200 microns and a thickness smaller than 5 microns. The productivity of the papermaking process and the quality of the obtainable paper are improved by using said starch particles.
