ABSTRACT:
A method is disclosed for the preparation of a hot transfer film that is pre-cut and pre-positioned for continuous application during the forming of plastic articles by an in-mold decorating technique. A carrier film is first bonded to the transfer film from which the hot transfer is prepared, to form a releasable laminate. The laminate is then printed with appropriate decorating indicia on the free surface of the transfer film component thereof. Printing may be single-stage or multi-stage, depending upon the indicia desired, and a subsequent metalization of the transfer film surface may be performed.
The fully printed laminate is then indexed into position and die-cut under conditions controlled to assure full penetration of the transfer film by the die, without penetration of the adjacent surface of the carrier film. Thereafter, the unwanted portions of the transfer film are stripped away, leaving the pre-cut decorated transfers, positioned on the carrier film for continuous indexing into position for the in-mold decoration of the plastic article being formed.
The present method eliminates post-treatment of the decorated molded article.
