Abstract
Abstract Coating and bonding agents based on mixtures of acetoacetates of polyvalent metals, diluents, copolymers of polymerizable acetoacetic esters having the general formula WHERE Y is a hydrocarbon radical and R is H or CH3, and acrylic and/or methacrylic esters and/or styrene given hard and clear films which are resistant to weathering and may chemicals.
