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 mainly of the halogenated rubber onto the substrate and then forming the magnetic layer over the mold releasing layer.
CONSTITUTION: Mold releasing layer 2 is composed mainly of the halogenated rubber such as the fluorinated rubber, chlorinated rubber or the like and especially the chlorinated rubber obtained by giving reaction of the chlorine to the double- combined part of the natural rubber. Such layer 2 is provided on substrate 1 made of polyester, release paper or the like. Then the magnetic powder of γ-Fe2O3 or the like is adhered onto layer 2 along with the vinyl chloride-vinyl acetate-vinly alcohol copolymer plus the binder of the polyurethane-group resin or the like, thus magnetic layer 3 being formed. In such way, a transfer sheet containing the mold releasing layer can be obtained, featuring the excellent mold releasing properties, wearing properties and chemical resistance each.
