    摘要: The information recording medium of the present invention is provided with a substrate and an information layer including a recording layer. Rerecording and reproducing of information are performed by irradiating the information layer with a laser beam. The recording layer contains, as its main component, a material composed of Te, O, and M, where M denotes at least one element selected from Ru, Rh, Pd, Ag, Re, Os, Ir, Pt, and Au. In the material, the content of Te atom is 1 to 19 atom %, the content of O atom is 20 to 70 atom % (preferably 40 to 70 atom %), the content of M atom is 11 to 79 atom % (preferably 11 to 59 atom %, and more preferably more than 35 atom %).

    摘要: Provided is a plastic eraser excellent in safety and environmental pollution resistance and, not detracting from the erasability thereof, further excellent in bleeding resistance and eraser dust gatherability. The eraser comprises a base resin such as a vinyl chloride resin and, as incorporated therein as a plasticizer, a liquid acrylic polymer having a glass transition point (Tg) of not higher than 0° C. The eraser may comprise the liquid acrylic polymer alone or as combined with one or more other plasticizers. Containing the liquid acrylic polymer as a plasticizer, the eraser has excellent bleeding resistance and excellent dust gatherability which could hardly be balanced.
