The present invention includes processes and methods of preparing the hybrid polymer latex for coating composition that can be used for traffic markings, transportation and signages. The process may comprise preparing an initial monomer mix pre-emulsion of unsaturated organic compounds, preparing an initial inorganic dispersion feed comprising modified inorganic component, preparing an initiator solution, and adding at least 2 parts per 100 parts polymer by weight of polyfunctional amines to result in final hybrid polymer latex. The coating composition obtained by the disclosed process provides superior qualities of moisture proofing, water repellence and early rain resistance to enhance durability of the product.

A polymer-encapsulated pigment dispersion is prepared from a mixture of (a) a carrier; (b) pigment particles; and (c) a polymeric dispersing agent having a polymer backbone, and an alkali-swellable copolymer component. The dispersing agent may provide efficient pigment wetting and dispersion using relatively low and thus economical dispersant amounts, and subsequently enable formation of polymer-encapsulating pigment dispersions that, when used in coatings, provide good opacity and good hiding characteristics, especially in titanium dioxide-containing coating compositions.
