Sizing of paper using a sizing agent in a dispersant system comprising a cationic organic compound and an anionic polyelectrolyte

摘要

An aqueous dispersion containing a cellulose-reactive sizing agent and a dispersant system comprising a low molecular weight cationic organic compound having a molecular weight less than 10,000 and an anionic stabilizer is claimed. Also claimed is the preparation of the dispersion and its use in the production of paper. A substantially water-free composition containing a cellulose-reactive sizing agent, a low molecular weight cationic organic compound having a molecular weight less than 10,000 and an anionic stabilizer is claimed. Also claimed is its preparation and use in the preparation of an aqueous dispersion of cellulose-reactive sizing agent.
