ABSTRACT:
Microcapsules having hard, thick walls are formed by dispersing an oily solution containing a crosslinking agent in an aqueous solution, and forming a polysalt in the aqueous solution, the polysalt including a high molecular weight polyanion and a polycationic polyamine having a functionality of at least three. The polyanion is preferably casein. If the surface of the microcapsules formed in the aqueous solution is lipophilized, the microcapsules easily separate from the solution by filtration. By use of a suitable wetting agent, the filter cake can be used in place of the pigment in any conventional printing ink. The microcapsules may be used in carbonless copy paper technology.
