Abstract
Abstract A resin composition which comprises a coupling agent in an amount of about 0.5 part by weight to about 50 parts by weight against 100 parts by weight of a copolymer composed of an aminoalkyl acrylate and/or aminoalkyl methacrylate and an ethylenically unsaturated monomer. The resin composition excels, as compared with the conventional ones, in terms of any properties to be developed toward a wide range of various substrates inclusive of inorganic materials and plastic materials, such as adherence, water resistance, weathering resistance and yellowing resistance, and consequently are advantageously used in such fields as coatings, adhesives and printing ink.
