Abstract
A media sheet has a substrate with an image-receiving layer disposed thereon. The image-receiving layer has a first pigment having particles with a size of about 50 to about 400 nanometers, a second pigment having plate-like particles, and a third pigment that either having a porous structure with an oil absorption of about 50 to about 300 cubic centimeters of oil per 100 grams, or a porous structure comprising substantially non-porous particles.
Claims21
A media sheet, comprising:
- a porous paper substrate;
- and
- an image-receiving layer disposed directly on the substrate, the image-receiving layer comprising a mixture including:
- a first pigment which is about 10 to 50% of the image-receiving layer by weight and having particles with a size of 50 to about 400 nanometers;
- a second pigment having particles with a plate-like shape and a median equivalent spherical diameter of about 0.9 micron to about 1.6 microns;
- and
- a third pigment having either a first porous structure with an oil absorption of about 50 to about 300 cubic centimeters of oil per 100 grams of the third pigment, or a second porous structure comprising substantially non-porous particles.
