  • Patent number: 8492308
    Abstract: The present invention provides a thermosensitive recording medium with excellent color developing sensitivity, moist heat resistance and plasticizer resistance, as well as excellent heat resistance, background coloring, light resistance and the like in the printed image. A diphenyl sulfone derivative containing a hydroxyl group on one end and an alkoxy group on the other end has a higher melting point than the one containing hydroxyl groups on both ends. As a result, the thermosensitive recording medium obtained using the diphenyl sulfone derivative as the color developing agent in the thermosensitive color developing layer has excellent heat resistance. However the color developing sensitivity of the thermosensitive recording medium generally declines simultaneously, when a color developing agent with a high melting point is ordinarily used.

  • Patent number: 8420847
    Abstract: A novel bis-phosphate compound is provided which can be applied to a wide range of reactive substrates and reactions as an asymmetric reaction catalyst and can realize an asymmetric reaction affording a high yield and a high enantiomeric excess. The bis-phosphate compound has a tetraaryl skeleton represented by General Formula (1). In an asymmetric reaction, an amidodiene and an unsaturated aldehyde compound are reacted with each other in the presence of the optically active bis-phosphate compound to give an optically active amidoaldehyde. The invention allows a reaction such as an asymmetric Diels-Alder reaction to proceed efficiently, which has been difficult with conventional mono-phosphate compounds.

  • Publication number: 20130068993
    Abstract: The formulation of the current invention provides better deicing and anti-icing performance than commercial acetate-based deicing solutions. The performance is consistently better in all testing categories including melting, penetration, undercutting, and friction. The corrosiveness is similar to commercial deicers, which may include corrosion inhibitors. Chemical analysis reveals that a potassium acetate solution provided by the invention contains formate and lactate in the prepared deicer.
