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.
