Abstract:
A recording substrate which comprises (a) a cellulosic substrate having a first surface and a second surface opposite the first surface; (b) on the first surface of the cellulosic substrate and in contact therewith, a first coating comprising (i) a cold-water-soluble hydrophilic binder polymer, (ii) an ink spreading/ink wetting agent, (iii) a cationic dye mordant, (iv) a lightfastness-imparting agent, (v) a filler, and (vi) an optional biocide; (c) on the first surface of the cellulosic substrate and in contact with the first coating, a second coating comprising (i) a hot-water-soluble or alcohol-soluble material and (ii) a phosphonium salt; and (d) on the second surface of the cellulosic substrate and in contact therewith, a third coating comprising (i) a binder polymer with a glass transition temperature of from about âˆ’50 to about 50Â° C., (ii) an antistatic agent, (iii) a lightfastness-imparting agent, (iv) a filler, and (v) an optional biocide.
