Processes are disclosed for preparing a printable and printed articles by coating a substrate with a composition containing a crosslinkable amine functional polymer and a polyfunctional isocyanate blocked by a blocking agent. The coated substrate is heated to a sufficient temperature to deblock the blocked polyfunctional isocyanate and thereby produce a crosslinked hydrophobic, ink receptive polymer layer on the substrate. Printed articles are prepared by forming an image on the crosslinked hydrophobic, ink receptive layer. In a preferred embodiment, the crosslinked hydrophobic, ink receptive polymer composition is characterized by a solvent resistance fraction of at least 0.6 and a solvent absorbance capacity of at least 300. The substrate of the printed article is preferably polymer, metal, glass, or paper, more preferably polymer film. A process for preparing printable articles wherein the substrate is a fluoropolymer is especially preferred.
本发明公开了一种制备可印刷和印刷品的工艺,方法是在基材上涂覆一种含有可交联胺官能团聚合物和被封端剂封端的多官能异氰酸酯的组合物。将涂层基材加热到足够的温度,使被封端的多官能异氰酸酯脱嵌,从而在基材上形成交联的疏水性油墨接受聚合物层。通过在交联疏水性油墨接受层上形成图像来制备印刷品。在一个优选的实施方案中,交联疏水性油墨接收聚合物组合物的特点是耐溶剂性至少为 0.6,溶剂吸收能力至少为 300。印刷品的基材最好是聚合物、金属、玻璃或纸,更优选聚合物薄膜。特别优选的是制备可印刷物品的工艺,其中基材是含氟聚合物。
