Abstract (en)

[origin: WO9832920A1] A process of making surface sized paper products, in which an aqueous, starch containing surface sizing composition is employed, and a corresponding aqueous, starch containing surface sizing composition are described. Besides starch at least one water soluble polymer and at least one water insoluble polymer are employed. Surprisingly a surface sizing is achieved by this combination which avoids the disadvantages of the use of a water soluble or a water insoluble polymer alone, but at the same time maintains the benefits of the use of water soluble or water insoluble polymer alone.
