A method for forming a sol-gel on a metal surface to provide an interface for promoting adhesion between the metal surface and an organic resin involves application of at least one metal alkoxide compound having at least one labile sulfur atom, and at least one metal alkoxide compound having at least one reactive moiety which is capable of bonding with an organic resin. The metal alkoxide compound having at least one labile sulfur atom is capable of bonding to various metal surfaces, including surfaces of noble metals, such as gold, by a sulfur-metal linkage with the metal surface. The metal alkoxide compound having at least one labile sulfur atom reacts with the metal alkoxide compound having at least one reactive moiety which is capable of bonding with the organic resin to form a sol-gel which bonds to the surface of the metal, and which includes reactive moieties which are capable of bonding with an organic resin. The method and coating compositions of this invention are useful for improving the adhesion of various organic resin coatings on various metal surfaces, including noble metal surfaces, such as gold.

Ce procédé de formation d'un sol-gel sur une surface métallique sert à constituer une interface favorisant l'adhérence entre la surface métallique et une résine organique, et il consiste à appliquer au moins un composé alcoxyde métallique possédant au moins un atome de soufre labile, et au moins un composé alcoxyde métallique possédant au moins une fraction réactive qui est capable de se lier avec une résine organique. Le composé alcoxyde métallique comprenant au moins un atome de soufre labile peut se lier à diverses surfaces métalliques, notamment des surfaces de métaux nobles, tels que l'or, par l'intermédiaire d'une liaison soufre/métal avec la surface métallique. Le composé alcoxyde métallique comprenant au moins un atome de soufre labile réagit avec le composé alcoxyde métallique, lequel possède au moins une fraction réactive capable de se lier avec la résine organique, afin de former un sol-gel qui se lie à la surface du métal, et possède des fractions réactives capables de se lier avec une résine organique. Le procédé et les compositions de revêtement de l'invention sont utiles pour améliorer l'adhérence de divers revêtements à base de résine organique, sur diverses surfaces métalliques, notamment sur des surfaces de métaux nobles, tels que l'or.
