The cord is a cord for reinforcing elastomers (10) that includes metallic filaments (1) and a resin filament (2) twisted together, the resin filament (2) being made from a polymeric material having a melting point or softening point of 80 to 160°C. The cord for reinforcing elastomers includes a core and at least one sheath layer, wherein, after vulcanization, a distance w between metallic filaments (1b) forming an outermost sheath layer is 100 µm or less, and, on a cross section of the cord taken along a direction orthogonal to an axial direction, a filling ratio, which is a ratio of an area of a polymeric material (3) derived from the resin filament (2) to a gap region is 52 to 120%, where the gap region is defined as a portion occupied by a material other than the metallic filaments (1) within a region formed by connecting the centers of the individual metallic filaments (1b) constituting the outermost sheath layer.

摘要： The present invention provides an information display panel capable of maintaining an excellent image property even after repeated rewrite, and particles for display media used therefor. The information display panel, in which at least one kind of display media including a charged particle for display media are sealed in a space between substrates at least one of which is transparent, for displaying an image by application of electrostatic force to the display media by means of an electronic field forming means, uses the particle for display media comprised of a mother particle, child particles and fine particles. The child particles, having a molecular structure of three-dimensional crosslinked structure and a particle diameter smaller than that of the mother particle which has no molecular structure of three-dimensional crosslinked structure, are embedded in a surface of the mother particle. It thereby hardens the surface of the mother particle. Then, the fine particles having the particle diameter smaller than that of the child particles are attached to the mother particle having the child particles embedded therein, it is thus possible to prevent the fine particles from being buried in the mother particles.

摘要： A display media particle used for an information display panel having display media constituted of particles sealed between two substrates, at least one of which is transparent, for displaying information by moving the display media, is formed of a mother particle 32 made from materials including a base resin having child particles 33 added to a surface thereof. The base resin is a thermoplastic resin having a viscosity of no more than 1000Pa · s at 260°C and a shear rate at 122s -1 , and a heatproof temperature at no less than 430°C. Since optimal conditions of the viscosity and the heatproof temperature are specified, it is possible to round the resin effectively by a heat treatment for spheronization as a post-treatment after manufacturing.
