The present invention relates to a coating composition for fibrous substances containing 25 to 75 percent by weight of pigment, and 0.5 to 25 weight percent of a polymer comprising 1 to 15 percent by weight of one or more monomers having sterically hindered secondary amine groups and 10 to 40 weight percent of a carboxylic acid monomer. The coating is useful on fibrous and non-fibrous substrates on which liquid inks will be fixed. The non-ionic polymer becomes cationic when contacted by anionic inks, and the cationic nature of the coating provides the substrate with an excellent point of attachment for inks and dyes, resulting in bright, crisp printed images. The coating is especially useful for ink-jet printing on paper, paperboard, textiles, non-wovens, wood, and films.
本发明涉及一种用于纤维物质的涂料组合物,该组合物含有 25-75%(重量百分比)的
颜料和 0.5-25%(重量百分比)的聚合物,该聚合物由 1-15%(重量百分比)的一种或多种具有立体受阻仲胺基团的单体和 10-40%(重量百分比)的
羧酸单体组成。该涂层适用于固定液体油墨的纤维和非纤维基材。非离子聚合物与阴离子油墨接触后会变成阳离子,涂层的阳离子性质为油墨和
染料提供了极佳的附着点,使印刷图像明亮、清晰。这种涂层尤其适用于在纸张、纸板、纺织品、无纺布、木材和薄膜上进行喷墨打印。
