Process for coating mineral, organic or metallic microscopic or macroscopic substrates, and the substrates so coated.

摘要

This invention relates to a process for coating microscopic and macroscopic substrates.

The process comprises essentially three steps, the first step consisting in coating a substrate with a first layer of a liquid medium containing a polyhydroxylated polymer, preferably, polyvinyl alcohol and a transition metal, preferably copper capable of forming a complex or already complexed, a second step consisting in applying on the first layer a polymerizable material capable of being grafted on the first layer, preferably a material containing acrylic or methacrylic unsaturations, and a third step consisting in causing the polymerization with grafting of the polymerizable material onto said first layer.
