Abstract: 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.

Abstract: This invention relates to a process for using computerized molecular interaction modeling to predict the adhesive interactions between a substrate and a polymer. The molecular modeling method may be used to predict and select optimal adhesion promoting monomers for use in latex polymer coatings, providing the best wet adhesion to alkyd-coated substrates. The molecular modeling method could also predict substrate polymer pairs having the least affinity, and thus the most useful as a release liner.

Abstract: A colloid composition is presented which contains an amphiphilic star polymer having potentially crosslinkable sites on the polymer backbone. The potentially crosslinkable site is either a sterically hindered silane monomer or an acetoacetoxy-containing monomer. When the crosslinkable site is a sterically hindered silane monomer the star polymer also contains an internal catalyst, and when the crosslinkable site is an acetoacetoxy group the colliod composition also contains a non-polymeric polyfunctional amine. The star polymer can be either a random or heteroarm star polymer. The colloid composition is useful in the formation and stabilization of emulsion polymers, as a replacement for surfactants currently used for this purpose. Emulsion polymers formulated with the colloid composition are especially useful for one-part coatings such as paints and adhesives.
