Traffolyte

Traffolyte was a brand name for multi-layered phenolic plastic sheets suitable for engraving. Each layer was a different colour so engraved letters or shapes would be a different colour from the unengraved portions. Thus it could be used for name tags, labels and signs.The material dates back to 1927, when it was first produced by Metropolitan-Vickers Electrical Ltd. at their Trafford Park factory in Manchester, U.K. for transformer labels. The complete business was sold to De La Rue Insulation Ltd. of Newcastle in 1945; De La Rue went out of this business in the early 1960's. There are a large number of companies manufacturing bi- and tri-layer phenolic engraving stock and it has become a generic term; no record of its having been a registered trademark in the US or UK has been found.

Sometimes it is spelled 'traffolite'.
