摘要： An image forming medium includes a substrate, and an imaging layer coated on or impregnated into said substrate, wherein the imaging layer includes an imaging composition including a photochromic or photochromic-thermochromic material dissolved or dispersed in a solvent or polymeric binder, wherein the imaging composition is imageable by light of a first wavelength and erasable in a short time period by a combination of heat and light of a second wavelength such that simultaneous erase with heat and light of the second wavelength is faster than erase by heat alone and exhibits a reversible transition between a colorless and a colored state.

摘要： A cholesteric display including a cholesteric liquid crystal, and a dipolar dopant having limited miscibility in the cholesteric liquid crystal is provided. In accordance with another aspect, a process is provided for forming a cholesteric liquid crystal composition by dissolving a dipolar dopant having limited solubility into a cholesteric liquid crystal. The liquid crystal composition can be utilized to produce a cholesteric display. The liquid crystal domains in the liquid crystal composition rotate away from a planar state in the presence of an applied electric field and the degree of rotation is a function of the applied electric field strength. The reflected color is then a function of the applied electric field.

摘要： An ink set is made up of at least three differently colored phase change inks, for example cyan, magenta and yellow, wherein at least one of the colored phase change inks is a photochromic ink that contains a photochromic material. Upon exposure to activating radiation such as ultraviolet light, the at least one photochromic ink changes to a color different from the color of the photochromic ink prior to exposure to the activating radiation.

摘要： Magnetic display devices include low-density silica coated magnetic and nonmagnetic particles. In a one-particle system, low-density silica coated magnetic particles coated by a sol-gel process are used in combination with non-magnetic particles. In a two-particle system, low-density silica coated magnetic particles coated by a sol-gel process are used in combination with low-density silica coated non-magnetic particles. Display devices employing silica coated magnetic particles minimize the tendency of the magnetic particles to aggregate. Silica coated magnetic particles in a display device results in a magnetic display with improved image stability. Low-density silica coated magnetic particles in a display device allow for particles to move easily through a dispersion fluid in response to a magnetic field.
