ABSTRACT:
A process for preparing an injection-molded article having a three-dimensional pattern on a surface thereof includes placing a master film of a thermoplastic resin having a three-dimensional master pattern formed on a region thereof into a mold such that the master pattern is exposed to the mold cavity. An injection-moldable resin is then injected into the mold cavity so as to cause a surface region of the resin to conform to the three-dimensional master pattern on the master film, and to thereby transfer the master pattern onto said surface region of the resin. The master film is then removed from the surface region of the injection molded resin to thereby expose said three-dimensional pattern formed thereupon. Preferably the master film is formed of a thermoplastic resin having a melting point greater than the injection molding temperature. Other lower melting point thermoplastic films can be used by metallizing the film's surface so that it withstands the injection molding temperature.
