Abstract
To make an underwater marker with indicia on it, an uncured or partcured base material of one color is prepared with the shape of the desired indicia cut out of it. The indicia are cut from uncured or partcured material of different color and are fitted into the cut-out in the base material to form a single layer. A transfer material bearing antifouling material is placed over the face of the layer and the assembly is pressed together to embed the antifouling material into the layer and to cure the contrasting materials together with each other and with an optionally underlying reinforcing layer. A backing sheet of the transfer material is stripped off to expose the particles.
