摘要:
A toner composition comprised of resin particles, pigment particles, and submicron colloidal domains of an ionomeric polymer or an interpolymer complex comprising a first polymer and a second polymer, preferably, independently selected from the group consisting of an ionophoric polymer and the ionomeric polymer. The ionomeric polymer and interpolymer complex are optionally complexed to a Lewis acid, a salt, or an ion thereof.

A multi-layer optical recording member for use with a recording laser for optical recording and retrieving information thereon, as well as a method of fabricating and using said member is described. The optical recording member comprises in sequential order a structural substrate, a thermally degradable polymer layer, a light absorbing recording layer, a thermally degradable polymer dielectric layer, and a reflective layer. The substrate and the thermally degradable polymer layers are stable under ambient light and temperature conditions and substantially transparent to the recording and reading optical radiation. The combined thicknesses of the light absorbing layer and the dielectric layer are such as to provide anti-reflecting conditionsat the recording wavelength and optical contrast between marked and unmarked areas at the reading wavelength. The optical recording member may be used with a single laser source for both recording and reading. Upon exposure to recording radiation, the portion of the light absorbing layer exposed is heated by the absorbed energy which in turn heats adjacent areas of both thermally degradable polymer layers to a level where at least some polymer decomposition with a consequent evolution of gaseous decomposition products occurs resulting in the formation of a hole in the exposed area of the heat absorbing layer.

Disclosed is an aqueous ink composition comprising an aqueous liquid vehicle, a colorant, and an additive wherein, when the ink has been applied to a recording substrate in an image pattern and a substantial amount of the aqueous liquid vehicle has either evaporated from the ink image, hydrogen bonds of sufficient strength exist between the additive molecules so that the additive forms hydrogen-bonded oligomers or polymers.
摘要:
Disclosed is a process which comprises reacting a polymer of the general formula ##STR1## or ##STR2## wherein x is an integer of 0 or 1, A is one of several specified groups, such as ##STR3## B is one of several specified groups, such as or mixtures thereof, and n is an integer representing the number of repeating monomer units, with a halomethylethyl ether, a hydrohalic acid, and acetic acid in the presence of a halogen-containing Lewis acid catalyst, thereby forming a halomethylated polymer.
摘要:
Disclosed is a dry toner composition which comprises a resin, hydrophilic silica particles having dyes covalently bonded to the particle surfaces through silane coupling agents, and a polymer having at least one segment capable of enhancing the dispersability of the silica particles in the resin and at least one segment capable of adsorbing onto the surface of the silica particles. In one embodiment, the polymer segment capable of adsorbing onto the surface of the silica particles is ionophoric and capable of complexing with a salt, thereby incorporating a toner charge control additive into the polymer.

Disclosed is a process which comprises contacting a sulfur-containing solvent with an oxidizing agent, said sulfur-containing solvent containing odor-causing impurities, thereby reducing odor. Another embodiment of the present invention is directed to a process for preparing an ink composition which comprises: (a) contacting a sulfur-containing solvent with an oxidizing agent, said sulfur-containing solvent containing odor-causing impurities, thereby reducing odor; and (b) admixing the sulfur-containing solvent with water and a colorant, thereby forming an ink composition.
