    • Compositions and methods of producing paper-based materials are disclosed. In general, the techniques utilize an amine-containing polymer, such as chitosan, to functionalize one or more components of a mixture used to form materials such as paper-based materials. Such components can include the fibers of a pulp and/or filler particles. In one instance, either the pulp or the filler particles are functionalized, but not both. Such functionalization can improve the qualifies of a paper-based material relative to when such functionalization is not utilized. Techniques and compositions are also described to further improve the qualities of a paper material by utilizing a complementary polymer which can couple with the amine-containing polymer.
    • 公开了生产纸基材料的组合物和方法。 通常,该技术利用含胺聚合物,例如壳聚糖,官能化用于形成诸如纸基材料的材料的混合物的一种或多种组分。 这些组分可以包括纸浆和/或填料颗粒的纤维。 在一种情况下,纸浆或填料颗粒是官能化的,但不是两者都是。 这种功能化可以提高纸质材料相对于不使用这种功能化的限制。 还描述了技术和组合物,以通过利用可与含胺聚合物偶联的互补聚合物来进一步提高纸材质量。

    • Compositions and methods of producing colored paper products and agents for making such products are disclosed. Surface-modified pigments can be manufactured to provide selected coloring in a paper product. The pigment can include filler particles that are bound to one or more dye components with a coupling agent, such as a silane coupling agent or a polymer such as a polycation. The pigment can also be formulated to produce a paper product with better particulate and/or fines retention, and/or higher strength by including components that can interact favorably with the fibers of a paper material. The surface-modified pigments can also be utilized to make coloring formulations such as inks for printers and other applications.
    • 公开了生产彩色纸制品的组合物和方法以及用于制造这种产品的试剂。 可以制造表面改性颜料以在纸制品中提供选择的着色。 颜料可以包括用偶联剂如一种或多种染料组分与硅烷偶联剂或聚合物如聚阳离子结合的填料颗粒。 还可以将颜料配制成通过包括能够与纸材料的纤维相互作用的组分来生产具有更好的颗粒和/或细粉保留力和/或更高强度的纸制品。 表面改性颜料也可用于制备着色配方如用于打印机和其它应用的油墨。
