SOLVENT RESISTANT PRINTABLE SUBSTRATES AND THEIR METHODS OF MANUFACTURE AND USE

摘要

A printable substrate, along with methods of its formation, is generally provided. The printable coating can include a base sheet defining a first surface and a second surface and a printable coating on the first surface of the base sheet. The base sheet can be constructed from a cellulosic nonwoven web and a saturant. The printable coating can include a plurality of inorganic microparticles and a crosslinked material, where the crosslinked material is formed from a crosslinkable polymeric binder and a crosslinking agent. An image can be formed on the printable substrate, such as by printing an ink composition onto the printable substrate (e.g., onto the printable coating).

主权项

1. A printable substrate, comprising:
a base sheet defining a first surface and a second surface, wherein the base sheet comprises a cellulosic nonwoven web and a saturant; a printable coating on the first surface of the base sheet, wherein the printable coating comprises a plurality of inorganic microparticles and a crosslinked material, and wherein the crosslinked material is formed from a crosslinkable polymeric binder and a crosslinking agent, and further wherein the printable coating comprises about 60% by weight to about 80% by weight of the inorganic microparticles, about 25% by weight to about 35% by weight of the crosslinkable polymeric binder, and about 0.01% by weight to about 1% by weight of the crosslinking agent, and wherein the plurality of inorganic microparticles comprises a mixture of a first plurality of first inorganic microparticles having a first average diameter and a second plurality of second inorganic microparticles having a second average diameter, wherein the first average diameter is smaller than the second average diameter.
