Abstract
A process for marking which enables a colored pattern formed by at least two different and contrasting colors to be created on a dark or black surface of a rubber article, which process includes preparing a light-colored rubber composition having at least one elastomer and at least two coloring agents of different light colors, giving the said composition its initial color, and then incorporating a dark or black masking agent into this colored composition in a limited proportion to darken or mask the initial color of the rubber composition. The process further includes causing a first laser beam of appropriate characteristics to interact in a first stage in order to reveal a first colored pattern part, followed in a second stage by a second laser beam of appropriate characteristics in order to reveal a second colored pattern part.
