Abstract
This invention is an indicia transfer and method for its use to impart indicia to polyolefin objects during rotational molding. The transfer is a laminate of at least two, and preferably, three coats on a carrier sheet, which is preferably a flexible, transparent polymer sheet. The coats, as successive layers on the carrier sheet are: an optional backing coat of a backing-coat pressure sensitive adhesive, an indicia coat of a colorants in a graphic or alphanumerical array, and a top coat of a pressure sensitive adhesive. The pressure sensitive adhesive used for the backing coat has a transition melting temperature less than the surface temperature of the mold to which the transfer is to be applied while the top-coat pressure sensitive adhesive has a temperature sensitive adhesive which becomes tacky at the demolding temperature to enable transfer of the coats to the interior surface of a rotational mold. All the coats have melting temperatures which are less than the molding temperature to enable transfer and fusing of the transfers into the surface of the molded part.
