Topcoat compositions, substrates containing a topcoat derived therefrom, and methods of preparing the same

This invention relates to an ink-receptive composition, comprising: (a) a filler; (b) a binder having a Tg of less than 30° C.; and (c) a cationic polymer; wherein the composition, when coated on a substrate, forms an ink-receptive coating which accepts ink loading greater than about 300%. The coati...

Zusammenfassung:This invention relates to an ink-receptive composition, comprising: (a) a filler; (b) a binder having a Tg of less than 30° C.; and (c) a cationic polymer; wherein the composition, when coated on a substrate, forms an ink-receptive coating which accepts ink loading greater than about 300%. The coating compositions provide a printable surface receptive to high loading of ink-jet inks which do not crack at loading in excess of 300%, and in one embodiment, do not crack at loading up to about 400%. In addition, the print shows superior liquid resistance and the print quality of the inks is improved and a reduction in bleeding of colors occurs. Also, printed article have outdoor durability especially those with overlaminates.
