    摘要： Disclosed is a process for preparing a compound of the formula wherein R1 and R1′, R2 and R2′, and R3 are as defined herein, said process comprising (I) reacting a diacid of the formula HOOC—R2—COOH with a diamine of the formula H2N—R3—NH2 to form an acid-terminated oligoamide intermediate of the formula HOOC—R2—CONH—R3—HNCO—R2′—COOH; and (II) reacting the acid-terminated oligoamide intermediate with a monoalcohol of the formula R1—OH in the presence of a tin or organic titanate catalyst, in the absence of a coupling agent, and in the absence of a solvent to form the product. Also disclosed is a composition prepared by the process.

    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 method of dispensing display fluid into an array of cells loads an array of quills with the fluid. inserts the array of quills loaded with the fluid into the array of cells, such that each quill is inserted into a separate cell, contacts an inner surface of the cells to cause the fluid to transfer from the quills to the cells, and seals the cells. A dispensing system has a first substrate having an array of quills arranged on a first pitch, a first fixture to hold the first substrate, a second substrate having an array of cells, wherein the cells are arranged on a second pitch that is proportional to the first pitch, a second fixture to hold the second substrate, and an alignment system to align the first substrate to the second substrate such that each quill dispenses a display fluid into selected ones of the cells. An array of quills reside on a substrate, the quills having a lateral extent less than a lateral dimension of a cell into which the quills will be inserted, and a vertical extent at least twice the vertical extent of a depth of the cells.

    摘要： An electrophoretic display medium includes one or more set of colored particles in a dielectric fluid, wherein at least one of the one or more set of particles are particles having acid functionality imparting a substantially uniform negative charge to the particles. The display medium is included in an electrophoretic display device by including the medium in a multiplicity of individual reservoirs of a display layer or layers that is located between conductive substrates.
