ABSTRACT:
This invention is an indica transfer and method for its use to impart indica to polyolefin objects during rotational molding. The transfer is a laminate of at least two coats on a carrier sheet, which is preferably a flexible, transparent polymer sheet. The coats, as successive layers on the carrier sheet are: an indica coat of indica material in a graphic or alphanumerical array and a top coat of a top-coat pressure sensitive adhesive. Preferably the transfer also includes a backing coat of a backing-coat pressure sensitive adhesive between the carrier sheet and the indica coat, The pressure sensitive adhesive used for the top coat has a transition temperature less than the mold surface temperature onto which the transfer is applied to enable transfer of the coats to the interior surface of a rotational mold. The pressure sensitive adhesive used for the backing coat has a transition temperature greater than the surface temperature of the mold to which the transfer is to be applied, and both pressure sensitive adhesives have transition temperatures which are below the molding temperature and preferably below the melt temperature of the molding polyolefin used to form the molded part.
