Abstract
Official abstract text for this publication.
A core/shell particle is provided, comprising: a water-absorbent, dye-fixing polymeric core, comprising: (a) a multivalent cation and a polymerization product of a monoethylenically unsaturated carbonyl-group containing monomer; (b) a nitrogen-containing polymer; or (c) a combination of (a) and (b); and a water-insoluble, porous polymeric shell, surrounding all or a portion of said core. A paper sizing or coating composition which incorporates the core/shell particles is provided. Recording sheets which include the composition, methods of making the composition and recording sheets, and methods for making an image are provided.
First claim
Opening claim text (preview).
What is claimed is: 1. A water-absorbent, dye-fixing core/shell particle, comprising: a water-absorbent, dye-fixing polymeric core, comprising: (a) a multivalent cation and a polymerization product of a homopolymer of a monoethylenically unsaturated carbonyl-group containing monomer; or (b) a combination of (a) and a nitrogen-containing polymer; and a water-insoluble, porous polymeric outer shell, surrounding all or a portion of said core; wherein when the carbonyl-group…
