A process for the production of paper, board and cardboard having high dry strength

The invention relates to a method for producing high dry-strength paper, pulpboard and cardboard by adding cationic, anionic and/or amphoteric starch as a dry-strength agent to the paper material, dehydrating the paper material to form sheets in the presence of cationic polymers as starch retention agents, and using cationic polymer retention agents to increase retention of dry-strength agents made from cationic, anionic and/or amphoteric starch during the production of paper, pulpboard and cardboard.
