Foamable aqueous compositions can be used to form light-blocking and light-colored foamed, opacifying elements with one or more dry foamed layers. The compositions contain: (a) 0.05 to 20 weight % of porous particles comprising a continuous polymeric phase and a first set of discrete pores, the porous particles having a mode particle size of 2 to 50 &#x3bc;m; (b) at least 20 weight % of a binder material (that can be curable); (c) 0.1 to 30 weight % of one or more additives including dispersants, plasticizers, inorganic or organic pigments or dyes, thickeners, flame retardants, biocides, fungicides, optical brighteners, tinting colorants, metal flakes, and inorganic or organic fillers; (d) water; and (e) at least 0.001 weight % of an opacifying colorant different from (c), which opacifying colorant absorbs electromagnetic radiation. The foamable aqueous composition can be aerated, disposed on a porous substrate, dried, and crushed on that porous substrate.

Foamed aqueous composition

A process for modifying the surface of a carbon black by contacting said carbon black with a conjugated diimine compound. The conjugated diimine compound may comprise various substituents to provide the carbon black with desired corresponding properties, such as groups to impart increased hydrophilicity and self-dispersibility to the carbon black. Other embodiments relate to novel carbon black products, which may be prepared according to a process of the invention. The carbon black products may be used in the same applications as conventional carbon blacks. Such uses include, but are not limited to, plastic compositions, aqueous inks, aqueous coatings, rubber compositions, paper compositions, and textile compositions. In a specific embodiment, the resulting surface modified carbon black is employed as a pigment in an aqueous inkjet ink composition.
