The present invention provides a surface coating composition including: an organometallic comound (I) and/or a hydrolytic condensation product thereof: an organic compound (II) having a primary and/or secondary amino group in its molecule; and a compound (III) having a functional group reactable with the amino group in its molecule. The surface coating composition is capable of forming a coating layer which exhibits excellent gas barrier properties, transparency, and flexibility. A resin molding formed with the coating layer is preferably used as a wrapping material and a substrate for liquid crystal display device.
