ABSTRACT:
An article comprising a thermoplastic polymer having an essentially planar surface provided with a surface pattern defined and encompassed by at least one continuous self-connecting retaining dam; at least a portion of the dam comprising at least one debossed region between at least two essentially parallel raised ridges; a further article comprising the foregoing article having a boss formed from a hardened resin over the surface pattern to a depth at least equal to the height of the highest of the raised ridges; and a method for manufacturing the articles by heating the surface to a temperature above the deformation temperature of the polymer and impressing the surface with a debossing die to form the portion of the article having the debossed region and raised ridges and introducing a liquid resin into the surface pattern followed by solidifying the resin to form the article having the boss.
