Abstract (en)

[origin: WO9941453A1] A method for improving high speed precision paper converting and reprographic operations by surface sizing paper used in high speed precision converting or reprographic operations with a reactive sizing agent and an inorganic filler, the filler being applied in an amount effective to improve paper runnability. A sizing composition useful as a surface size in this invention is a 2-oxetanone reactive sizing agent and an inorganic filler, in a weight ratio of inorganic filler to reactive surface size of about 0.1:1 to about 10:1. Paper made by this method is also within the scope of this invention.
