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.

L'invention concerne un procédé destiné à améliorer les opérations reprographiques et de conversion de papier de précision rapide par collage en surface du papier utilisé dans les opérations reprographiques ou de conversion de précision rapide avec un agent de collage réactif et une charge organique, la charge étant appliquée en une quantité efficace pour améliorer le comportement du papier. Une composition de collage utile en tant que colle de surface dans cette invention comprend un agent de collage réactif constitué de 2-oxétanone et d'une charge inorganique, en un rapport pondéral entre la charge inorganique et la colle de surface réactive d'environ 0,1:1 à environ 10:1. Le papier produit selon ce procédé fait également partie intégrante du champ d'application de cette invention.
