| 摘要 |
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.
