Abstract

PURPOSE: To obtain a transfer sheet featuring the excellent mold releasing properties, wearing properties and chemical resistance each by providing the mold releasing layer composed of the halogenated rubber, a kind of the cyclized rubber and the paraffin each onto the substrate and then forming the magnetic layer over the mold releasing layer.
CONSTITUTION: Mold releasing layer 2 is composed of the halogenated rubber such as the chlorinated rubber obtained by giving reaction of the chlorine to the double- bond part of the natural rubber, a kind selected from the cyclized rubber the rubber molecule of which is cyclized partially and the paraffin each. Such layer 2 is then provided onto substrate 1 made of polyester, release paper or the like. Then the magnetic powder of γ-Fe2O3 or the like is coated onto layer 2 along with the vinyl chloride-vinyl acetate-vinyl alcohol copolymer plus the binder of the polyurethane- group resin or the like. Thus magnetic layer 3 is formed. In such way, a transfer sheet containing the mold releasing layer can be obtained with the excellent mold releasing properties, wearing properties and chemical resistance each.
