Title:
GRAPHICS TRANSFERS FOR USE IN ROTATIONAL MOLDING
Document Type and Number:
WIPO Patent Application WO2002094557
Kind Code:
B1
Abstract:
This invention is an indicia transfer and method for its use to impart indicia to polylefin objects during rotational molding. The transfer is a laminating of at least three coats on a carrier sheet, which is preferably a flexible, transparent polymer sheet. The coats, as successive layers on the carrier sheet are: a backing coat of a first pressure sensitive adhesive, an indicia coat of a colorant in a graphic or alphanumerical array, and a top coat of a second pressure sensitive adhesive. 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 while the pressure sensitive adhesive used for the top coat has a transition temperature less than the mold surface temperature to enable transfer of the coats to the interior surface of a rotational mold.
