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 (42) to produce an ink printable article (40) forms an ink-receptive layer (41) which accepts i...

Beschreibung
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 (42) to produce an ink printable article (40) forms an ink-receptive layer (41) which accepts i nk loading greater than about 300%. The ink printable article is printed with i nk jet inks. The coating compositions provide a printable surface receptive to high loading of ink-jet inks which do not crack at loading of excess of 300% , and in one embodiment, do not crack at loading up to about 400%. The printed article shows superior liquid resistance and the print quality of the inks i s improved and a reduction of bleeding of colors occurs. The printed articles have good outdoor durability especially when overlaminate (43) is placed on the article.
