A composition is provided, which comprises a water-soluble salt of a divalent metal; a complexing agent having an affinity for the divalent metal; and an optical brightening agent. Methods of using the composition, and recording sheets which include the composition, are also disclosed.

Composition and recording sheet with improved optical properties

A recording sheet is provided, which comprises: a paper substrate comprising a plurality of cellulosic fibers; and a sizing agent comprising a water soluble divalent metal salt; wherein the paper substrate and sizing agent cooperate to form an I-beam structure. Methods of making and using the recording sheet are also provided.

Recording sheet with enhanced print quality at low additive levels

The present invention relates to a sizing composition that, when applied to paper substrate, creates a substrate, preferably suitable for inkjet printing, having increased print density, and print mottle, as well as print sharpness, low HST, and/or image dry time, the substrate preferably having high brightness and reduced color-to-color bleed as well. In addition, the present invention relates to a method of reducing the HST of a paper substrate by applying the sizing composition to at least one surface thereof. Further, the application relates to methods of making and using the sizing composition, as well as methods of making and using the paper containing the sizing composition.

Paper substrate containing a wetting agent and having improved printability

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: () brightness; () opacity; () paper smoothness; () print quality; () optionally ink dry time (e.g., for ink jet printing where the sizing composition has option); and () optionally minimizing or eliminating edge welding (e.g., for paper webs used in, for example, form printing).
