Thermosetting dry transfer

Abstract

Abstract TO PROVIDE A SUITABLE BACKGROUND FOR THE DESIGN AND/OR INCREASED TRANSFER CHARACTERISTICS. THE RESIN FILM LAYER MAY COMPRISE A PAIR OF LAYERS WITH THE UPPER LAYER BEING THE SAME AS THE ABOVE IDENTIFIED BLOCKED AND SUBSTANTIALLY UNCURED SINGLE LAYER RESIN FILM AND A PARTIALLY CURED RESIN FILM LAYER OF SIMILAR COMPOSITION BEING INSERTED UNDER IT. THIS COMPOSITE SYSTEM PERMITS A DESIGN HAVING SUPERIOR ABRASION AND HEAT RESISTANCE TO BE APPLIED TO MATERIALS WITH EXTREME RAPIDITY. A COLORED DESIGN IS APPLIED UPON A HIGH RELEASE CARRIER SHEET, SUCH AS PAPER COATED WITH A HIGH RELEASE AGENT. A RESIN FILM LAYER INCORPORATING A COMBINATION OF A MIXTURE OF BLOCKED POLYRETHANE AND VINYL COPOLYMER RESINS IS DEPOSITED OVER THE COLORED DESIGN ON THE CARRIER SHEET. THE DESIGN IS TRANSFERRED AND THERMALLY SET BY APPLICATION OF HEAT AND PRESSURE. THE DESIGN MIGRATES WITHIN AND IS PROTECTED BY THE HEAT SET RESIN FILM. AN ADDITIONAL RESIN LAYER SUCH AS A PIGMENTED THERMOPLASTIC PLASTISOL, MAY BE DEPOSITED ON THE TRANSFER OVER THE DESIGN-COVERING LAYER
