  • Patent number: 6656551
    Abstract: The present invention provides for an indicia bearing elastomeric article with a smooth outer surface and a process for making the article. The indicia bearing elastomeric article includes a polymer film having indicia on one of its surfaces bonded to and flush with an elastomer layer. Since the outer surface of the article is without surface irregularities caused by the known transfer release techniques, power transmissions belts employing the invention do not generate the unwanted noise caused by the irregular surface contacting pulleys and idler rolls. The indicia provided by the invention can provide durable labeling for the article which remains visible throughout the useful life of the article.
