Prearation for deacidification and ensuing rise of solidity and stability of paper information carrier and method for using thereof

摘要

It is described an aqueous solution of zirconium compounds, consisting of zirconate-potassium carbonate with a concentration the most 6 % by weight and containing an addition of water-soluble polysaccharide compounds with a concentration the most 2 % by weight. The said solution is coated or sprayed to information paper carriers for the most 30 min. at room temperature. Thus, the treated information paper carriers are further dried and pressed at room temperature, if it is necessary.
