Abstract: The highly flame-retardant acrylic fiber of the invention comprises 1 to 20 weight % of a glycidyl methacrylate polymer and 1 to 20 weight % of antimony oxide in an acrylonitrile copolymer obtained with use of monomers containing 20 to 70 weight % of at least one halogen-containing monomer, and can be cross-linked by heating. The cross-linked fiber and a highly flame-retardant composite produced with it are rarely ignited and difficult to be perforated with flame.

Abstract: A multi-monitor is provided with a first display device having a display screen and a second display device having a display screen smaller than the display screen of the first display device, and a supporting mechanism which is mountable on an outside portion of the first display device, and supports the second display device rotatably about a first axis and a second axis intersecting the first axis. The first second display device is driven in accordance with the same operation system as the first display device.

Abstract: Disclosed is a printing medium useful for inkjet printing and provides opacity for either with or without back light applications. A printing medium made in accordance with the present invention includes a substrate, a first coating layer disposed on the substrate, and a second coating layer disposed on the first coating layer. The second coating layer has a microporous structure and comprises at least one hydrophobic polymer and at least one liquid absorbing filler dispersed substantially throughout the at least one hydrophobic polymer.

Abstract: A polymer composition comprising2-50 parts by weight of a fine particles component dispersed in a matrix described later, of (1) a high-nitrile (co)polymer, wherein the proportion of the nitrile polymeric unit (a) is at least 86% by weight based on the total of the high-nitrile (co)polymer, and98-50 parts by weight of a matrix of (2) a low-nitrile copolymer comprising the nitrile polymeric unit (a), the acrylic ester polymeric unit (b) and the aryl vinyl polymeric unit (c), wherein the proportion of the polymeric unit (a) is 50-85 % by weight and the polymeric unit (b) and the polymeric unit (c) occupy the remaining portion.
