Abstract: Heat transfer sheets for dye sublimation are provided, along with methods of their formation and use. The heat transfer sheet for dye sublimation may include a base sheet and a dye sublimation coating on a surface of the base sheet. The dye sublimation coating generally includes a plurality of microparticles dispersed in a polymeric binder, with the plurality of microparticles including a mixture of tack-inducing microparticles and oxide microparticles.
Abstract: A texturized printable paper, along with methods of its formation and use, is provided. The texturized printable paper may include a base sheet having a first surface and a second surface, and a texturized printable coating on the first surface of the base sheet. The texturized printable coating may include a starch component; a plurality of first calcium carbonate particles having an average particle size of about 12 ?m to about 50 ?m; a plurality of oxide microparticles; and a plurality of polymeric microparticles having an average particle size of that is about 0.1 ?m to about 1 ?m.
Abstract: Printable substrates that provide a glossy printable surface with solvent resistance are provided. The printable substrate may include a base sheet having a first surface and a second surface, and a printable coating on the first surface. The printable coating includes a film-forming binder mixture, a crosslinking agent, a partially hydrolyzed polyvinyl alcohol, a first plurality of first silicon dioxide microparticles, a second plurality of second silicon dioxide microparticles, and a cationic dye fixative. The printable substrate may have a gloss level of about 50 to about 60 based on measurement of a gloss meter set with an angle of measurement of 75 degree on the external surface of the printable coating.
Abstract: Methods are generally disclosed for forming and using a release sheet. To form the release sheet, a release coating is applied over a first surface of a base sheet. Generally, the release coating includes a fatty alcohol ester of acrylic acid and a curable monomer, and can also include a curable polymeric resin. Then, the release coating can be cured. In one particular embodiment, the release coating can be substantially free from siloxanes. The release sheet formed according to this method is also generally provided, along with methods of forming a casting sheet using the release sheet are also generally provided.

Abstract: Methods for forming a hydroentangled scrim sheet are provided. The method can include hydroentangling a scrim sheet having a first layer of staple fibers on a first side of the scrim sheet and a second layer of staple fibers on a second side of the scrim sheet to form a hydroentangled scrim sheet; calendaring the hydroentangled scrim sheet to form a calendared hydroentangled scrim sheet; impregnating the hydroentangled scrim sheet with a saturant composition; drying the saturant composition impregnated into the calendared hydroentangled scrim sheet; applying a bond coat onto a surface of the calendared hydroentangled scrim sheet; and applying a top coat onto the bond coat. The top coat is, in one embodiment, configured to provide a surface for further coatings thereon.
Abstract: A security document, along with its methods of formation, is provided. The security document may include a base sheet, a colored coating on the base sheet, a foil laminate on at least a portion of the colored coating, and an outer lacquer coating over the colored coating such that the foil laminate is embedded between the colored coating and the outer lacquer coating. The outer lacquer coating may include a polymeric resin, and may also include a crosslinking agent and a wetting agent.

Abstract: Methods and kits for treating a fibrous substrate prior to forming an image thereon are provided. The method can include positioning a treatment sheet adjacent to the fibrous substrate, transferring a salt (e.g., calcium chloride, magnesium chloride, or a mixture thereof) from the treatment sheet to the fibrous substrate using a wetting solution (e.g., an aqueous solution, such as water) to carry the salt from the treatment sheet into the fibrous substrate, and drying the fibrous substrate such that the salt remains in the substrate. For example, the transfer of the salt from the treatment sheet into the fibrous substrate can be accomplished via pressing the backside of the treatment sheet such that the wetting solution flows from the treatment sheet into the fibrous substrate while carrying the salt.
