Abstract
Hybrid latex emulsions are disclosed which can be used in the formation of coating compositions having good blush resistance, abrasion resistance, blister resistance, hardness and scratch resistance. In some embodiments, the coating compositions are used to coat substrates such as cans and packaging materials for the storage of food and beverages. Hybrid latex emulsions of the invention may be prepared by mixing an ethylenically unsaturated monomer component and a stabilizer in a carrier to form a monomer emulsion, and reacting the monomer emulsion with an initiator to form the hybrid latex emulsion. The ethylenically unsaturated monomer component may include an organosilane compound, which may include a reactive organic group and a hydrolysable inorganic alkoxysilane.
