Topcoat compositions, substrates containing a topcoat derived therefrom, and methods of preparing the same
摘要：
This invention relates to an ink-receptive composition, including: (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.
摘要（中）：

本发明涉及一种油墨接收组合物，包括：（a）填料; （b）Tg小于30℃的粘合剂; 和（c）阳离子聚合物; 其中所述组合物当涂覆在基材上时形成接受大于约300％的油墨负载的油墨接受涂层。 涂料组合物提供可接受高负载的喷墨油墨的可印刷表面，其在装载时不会破裂超过300％，并且在一个实施方案中，在高达约400％的加载下不破裂。 此外，印刷品显示出优异的液体阻力，并且油墨的打印质量得到改善并且颜色的渗色减少。 此外，印刷品具有户外耐久性，特别是具有层压板的那些。
