This invention is a process for electrolessly metallizing an article to provide on the surface thereof a metal coating incorporating therein particulate matter, in which the process comprises contacting the surface of said article with an electroless metallizing bath essentially free of heavy metals, an electroless metallizing bath used in the process, and articles with coatings resulting from the process. La présente invention concerne un procédé de métallisation par dépôt autocatalytique d'un article, ce procédé étant utilisé pour former sur la surface dudit article, un revêtement métallique renfermant de la matière particulaire. Le procédé consiste à mettre en contact la surface de l'article avec un bain de métallisation par dépôt autocatalytique sensiblement dépourvu de métaux lourds. Cette invention porte également sur un bain de métallisation par dépôt autocatalytique utilisé dans le procédé et des articles dont le revêtement a été formé au moyen du procédé selon l'invention.
