Abstract: The invention is concerned with coated paper. By precoating paper with starch and insolubilized alginate, the amount of transferable coating e.g. in record materials, needed per unit area can be reduced. This advantage can be achieved with small amounts of alginate, e.g. less than 0.05 gram per square meter per side, and high starch to alginate weight ratios e.g. 85:1.
