Abstract (en)
[origin: EP1036881A1] The raw lamination paper is composed of cellulose fibers and filling materials from a paper mass of a cellulose mixture containing an unmodified and a cationic modified cellulose. The modified cellulose has a cation charge of 20-300 mmol/kg. The cellulose fibers are modified with a quaternary ammonium compound with a glycidyl function. The cationic modified cellulose forms at least 5 wt% of the cellulose mixture, using a short fiber cellulose for modification. The paper mass contains a wet strength agent in a vol. of 0.3-2.0 wt% of the cellulose. The filling material is titanium oxide, calcium carbonate, kaolin, talcum or a mixture of them.
