Zusammenfassung:	PCT No. PCT/EP97/01308 Sec. 371 Date Aug. 19, 1998 Sec. 102(e) Date Aug. 19, 1998 PCT Filed Mar. 14, 1997 PCT Pub. No. WO97/35068 PCT Pub. Date Sep. 25, 1997Disclosed are a paper size consisting essentially of a) alkyl ketene dimer and/or alkenyl succinic acid anhydride; b) degraded, liquid cationic starch having a cationic charge density of 0.5 to 3.5 meqv/g, a degree of substitution of more than 0.1 and a viscosity of less than 10000 cps (30% by weight solution in water at 25 DEG C.); and c) water, and a process for making paper products in which this paper size is added to the pulp. The invention allows the production of AKD and/or ASA sizes on-site in paper plants using simple mixing equipment.
