摘要： [Problems] An object of the present invention is to provide: thermochromic color-memory composition which effectively expresses a property of being capable of interchangeably memorizing and retaining colors and is thus applicable to various fields; and thermochromic memory microcapsule pigment encapsulating the same. [Means for Solution] Provided are thermochromic color-memory composition and thermochromic color-memory microcapsule pigment encapsulating the same, the thermochromic color-memory composition comprising: (a) a component composed of an electron-donating color-developing organic compound; (b) a component composed of an electron-accepting compound; and (c) a reaction medium which comprises an ester compound represented by the following Formula (1) and controls color reaction between the components (a) and (b): (wherein, R represents an alkyl group having 4 to 22 carbon atoms, a cycloalkylalkyl group having 5 to 12 carbon atoms, a cycloalkyl group having 4 to 8 carbon atoms or an alkenyl group having 4 to 22 carbon atoms; X represents a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 to 4 carbon atoms or a halogen atom; and n represents 0 or 1).

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.

摘要： An eraser dispenser is provided which can store in a dispenser body (1) an eraser longer than the overall length of the dispenser body (1). The eraser dispenser enables the eraser to be used without replacement with a new one for a long period of time. The eraser dispenser includes: a dispenser body (1) which is enclosed by an outer circumferential wall (2) having a distal opening (4) and has a storing chamber (8) capable of storing therein an eraser that is longer than the overall length of the dispenser body (1); and a cover (3) which covers the dispenser body (1). The eraser dispenser further includes; an external operation member (11) which partially projects from the outer circumferential wall (2) and is operated from the outside of the dispenser body (1); a driving roller (13) which is operated by the external operating member (11); a receiving member which is disposed opposite to the driving (13) roller with the eraser held therebetween; and a stopper which prevents a rotary button (11) as the external operation member (11) from undergoing reverse turn.

摘要： The invention concerns a rubber eraser made of a binder and plasticizer plus, optionally, fillers, colorants and/or other additives, the rubber containing as binder a polyalkyl methacrylate (PAMA), in particular polymethyl methacrylate (PMMA), polyethyl methacrylate (PEMA), polypropyl methacrylate (PPMA), polybutyl methacrylate (PBMA) and/or copolymers thereof. In addition, the invention concerns processes for the manufacture of rubber erasers of this kind, in which either a plastisol consisting of fine-grained polyalkyl methacrylate and plasticizer is first formed and any fillers, internal lubricants, colorants and/or other additives then added to the plastisol, or the PAMA powder, filler and any other dry components such as internal lubricants, pigments, etc., are intimately mixed in the dry state and the liquid plasticizer added to this mixture and mixed or kneaded in.
