Disclosed is a carrier suitable for use with an electrophotographic developer and an electrophotographic developer containing the carrier. In particular, the carrier is powder coated and comprises a copolymer of cyclohexylmethacrylate and dimethylaminoethylmethacrylate.

Carrier and developer

The instant disclosure describes methods for preparing latex resins for coated carriers using surfactant partitioning, which resins exhibit both lower &#x3b6; potential and greater latex stability, while not adversely affecting particle size, toner charge or other metrics.

Powder Coated Carrier

Disclosed is a process for preparing a compound of the formula wherein Rand R', Rand R&#x2032;, and Rare as defined herein, said process comprising (I) reacting a diacid of the formula HOOC&#x2014;R&#x2014;COOH with a diamine of the formula HN&#x2014;R&#x2014;NHto form an acid-terminated oligoamide intermediate of the formula HOOC&#x2014;R&#x2014;CONH&#x2014;R&#x2014;HNCO&#x2014;R&#x2032;&#x2014;COOH; and (II) reacting the acid-terminated oligoamide intermediate with a monoalcohol of the formula R&#x2014;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.

Process for preparing amide gellant compounds with aromatic end groups

The methods of manufacturing a curable wax, such as an acrylate of a hydroxyl-terminated polyethylene wax having the structure CH&#x2014;(CH)&#x2014;CHOH, where n=22-24, are disclosed. The methods may include reacting a wax having a transformable functional group and a curable compound in the presence of an organic solvent to form an acrylate. The methods may further include removing excess curable compound using hot water having a temperature of more than 85&#xb0; C., and solidifying the acrylate. The methods may thereby provide safe and cost effective methods for curable wax production at large scale.

Scalable process for synthesis of a curable wax

Powder coated carrier

The methods of manufacturing a curable wax, such as an acrylate of a hydroxyl-terminated polyethylene wax having the structure CH&#x2014;(CH)&#x2014;CHOH, where n=22-24, and removing a fouled material in a reactor are disclosed. The methods may include reacting a wax having a transformable functional group and a curable compound in the absence of an organic solvent to form an acrylate. The methods may further include removing excess curable compound using hot water having a temperature of more than about 85&#xb0; C., solidifying the acrylate, removing the acrylate, and removing a fouled material in the reactor by emulsification.

Solvent-free process for synthesis of a curable wax

Disclosed is a technique for producing bichromal balls that are adapted for use in high temperature applications. The bichromal balls find particular application in signs and display devices that can be used in environments in which the temperature exceeds 40&#xb0; C.

Bichromal balls

An electrophoretic display device includes a display layer of a multiplicity of individual microcapsules containing a display medium therein and conductive substrates, at least one of the conductive substrates being transparent, wherein the display layer is located in between the conductive substrates, and wherein the display medium includes one or more set of colored particles in a dielectric fluid and has an electric conductivity of about 10to about 10S/m. The microcapsules may be made by encapsulating the display medium in the wall forming material of the microcapsules, and for example a complex coacervation process may be used.

Electrophoretic display device

Continuous miniemulsion polymerization process

A method for producing a display capsule includes the following steps. A multichromal bead having at least two surfaces differing from each other in optical and electrical characteristics is formed. A dispersing agent on an outer surface of the multichromal bead is applied, preferably via spray coating. The multichromal bead is then encapsulated. The invention is also directed to a method for producing multichromal capsules. A multichromal bead having at least two surfaces differing from each other in optical and electrical characteristics and further includes a charge control additive. A dispersing agent is applied on an outer surface of the multichromal bead to prevent diffusion of the charge control additive from the multichromal bead. The multichromal bead is encapsulated at an encapsulation reaction temperature greater than 40&#xb0; C.

Display capsules and a method of manufacturing thereof

An electrophoretic display includes a transparent polymeric film including at least one cavity including a first particle species and a second particle species. Application of an electrical field causes the first particle species and the second particle species to separate from one another, and align on opposite sides of the cavity. Subsequent electric field applications cause migration of the first and second particle species, affecting a color state of the display. The electrophoretic display may be fabricated from multiple display cells arranged on a substrate.

Two particle electophoretic systems, electronic displays including two particle electophoretic systems, and methods for producing the two particle electophoretic systems

A display member for use at a temperature greater than at least about 40&#xb0; C. The display member includes an arrangement of a plurality of optically anisotropic rotatable elements comprising a purified polymer. The plurality of rotatable elements have a surface in contact with an enabling fluid, the rotatable elements being electrically dipolar in the presence of the enabling fluid and being subject to rotation upon application of an electric field.

Display members
