Disclosed is a hybrid polymer latex, a coating composition that can be used for traffic markings, transportation and signages. The coating composition includes polymerization products of organic monomers and a nanoparticulate dispersion of inorganic components, which are associated through covalent or coordinate bonds with the polymer such that there is homogenous integration and association of the modified inorganic component with the organic fraction in the polymer latex which increases abrasion properties of the coating composition. Additionally, the composition discloses additives in the form of polyfunctional amines which provide superior qualities of moisture proofing, water repellence and early rain resistance to enhance durability of the product. The present invention also includes processes and methods of preparing the hybrid polymer latex for coating composition.
