Abstract
Embodiments of the present invention provide a paper surface sizing composition, a paper web coated on one or more sides or surfaces with a paper surface sizing composition, and a method for treating one or more sides of the paper web with a paper surface sizing composition to impart benefits relating to one or more of the following properties: (1) brightness; (2) opacity; (3) paper smoothness; (4) print quality; (5) optionally ink dry time (e.g., for ink jet printing where the sizing composition has option); and (6) optionally minimizing or eliminating edge welding (e.g., for paper webs used in, for example, form printing).
