摘要：
A magnetic display sheet of the present invention comprises:
a magnet sheet having a magnetized surface, and a non-magnetized surface, which magnet sheet comprises: 400 to 1,900 parts by weight of at least one kind of magnetic particles selected from the group consisting of magnetoplumbite-structure ferrite particles and rare-earth magnet particles, as a filler, and 100 parts by weight of a binder comprising 50 to 95% by weight of at least one thermoplastic elastomer selected from the group consisting of a styrene-isoprene-styrene block copolymer resin, a styrene-ethylene.butylene-styrene block copolymer resin and an ethylene-propylene copolymer rubber, and 5 to 50% by weight of at least one soft polyolefin selected from the group consisting of a propylene homopolymer and a propylene-ethylene copolymer; and
a printing paper sheet for being printed on, said paper sheet being bonded to said non-magnetized surface of said magnet sheet.
Such a magnetic display sheet is excellent in flexibility, mechanical properties, storage stability and product stability.
