    摘要： A process for preparing a dispersion dyed color toner for developing latent electrostatic images includes dyeing a particulate polymer resin in organic medium in which the resin is not soluble. The resin is a functionalized resin having sites suitable for interacting with functionalized dyes have corresponding functionality. The functionalized dye is applied to the resin particles typically with a dyeing aid, or surfactant. The particle size distribution of the polymer resin is substantially unchanged during the toner preparation process.

    摘要： A process for producing microspheric toner particles suitable for color toner applications includes forming coarse particles of an amorphous polymer with one or more pigments and optionally a charge control agent followed by reducing the particle size such that it is suitable as toner for high resolution electrostatic imaging. A step of comminuting the particles includes forming a dispersion of the particles in a liquid organic medium and applying shear in the presence of a surfactant. In another embodiment, the invention discloses a process for producing microspheric particles of substantially amorphous resin with an average diameter in the range of from about 2 to about 10 microns. Preferred resins include amorphous polyester resins and ethylene/norbornene copolymers.

    摘要： A three-dimensional electro-optic waveguide is formed as a channel in a structure made of an organic non-linear optical polymer. A poling electric field is maintained in a portion of the polymer structure defining the channel, and the polymer structure is heated above the glass-transition temperature to enable dipolar moieties of the polymer to become aligned by the poling field. Heating continues until the dipolar moieties are sufficiently aligned to produce a higher index of refraction in the channel portion than in adjacent cladding portions of the polymer structure for at least one polarization of optical radiation propagating through the channel. The poling field is maintained as the polymer structure is then cooled below glass-transition temperature, thereby preserving alignment of the dipolar moieties (and hence preserving the differential index of refraction) in the channel portion of the polymer structure. Guided modes of optical radiation of at least one polarization can be supported in the channel.
