摘要:
This invention relates to a poly(ethylene terephthalate)-based photographic film base having improved properties with regard to cutting, perforating, and other finishing or phototofinishing operations. The film base comprises a material in which a specified amount of monomeric units derived from 1,4-cyclohexane dimethanol (CHDM), such that the film base has a specified cutting-related property. The level of CHDM in the PET-based polyester material can be adjusted either by physical blending of polyesters containing CHDM monomeric units or by synthetic incorporation of CHDM monomer units into a PET-based polyester backbone.
摘要:
A highly useful photographic film base containing a miscible blend of is polyester containing at least 30 weight percent cyclohexylene dimethanol, CHDM/EG-PE, and a polycarbonate containing bisphenols, BP-PC, in specified proportions. Photographic elements prepared with this film base have a lesser tendency to take core-set and post process curl than do elements prepared with polyester containing cyclohexylene dimethanol, CHDM/EG-PE, film base.
摘要:
The present invention is a method of manufacturing toner particles that includes providing a first emulsion of a first aqueous phase comprising a pore stabilizing hydrocolloid dispersed in an organic solution containing a polymer. The first emulsion is dispersed in a second aqueous phase to form a second emulsion that is sheared in the presence of a stabilizing agent to form droplets of the first emulsion in the second aqueous phase. The organic solution is evaporated from the droplets to form porous toner particles.
摘要:
A dye-donor element, a method of printing using the dye-donor element, and a print assembly including the dye-donor element are described, wherein the dye-donor layer of the dye-donor element includes ethyl cellulose as a binder. The dye-donor element is capable of printing a defect-free image on a receiver element at a line speed of 2.0 msec/line or less while maintaining a print density of at least 2.0.
摘要:
The present invention provides a dispersion comprising wax particles dispersed with a polymeric dispersant in a water immiscible solvent, wherein the dispersant comprises a wax-compatible polyolefin segment and a polyester compatible oleophilic polar segment. The invention is further directed towards a method of manufacturing such a wax dispersion, and towards methods of manufacturing wax-containing polymer particles by limited coalescence processes employing such a wax dispersion. In particular embodiments, the invention is directed towards chemically prepared toner derived from wax dispersions of the invention that shows improved toner performance.
摘要:
This invention relates to a poly(ethylene terephthalate)-based photographic multilayer film base having improved properties with regard to cutting and finishing operations compared to conventional PET film base. A specified amount of monomeric units derived from 1,4-cyclohexanedimethanol (CHDM) is used in at least two layers of the multilayer structure, such that the multilayer film base has a specified cutting related property.
摘要:
The invention relates to an imaging member comprising an image layer and a support comprising at least one layer comprising an inorganic particle having an aspect ratio of at least 10 to 1, a lateral dimension of between 0.01 &mgr;m and 5 &mgr;m, and a vertical dimension between 0. 5 nm and 10 nm, and polymeric resin.
摘要:
A highly useful photographic film base comprises a miscible blend of is syndiotactic polystyrene, SPS, and a polyxylylidene ether, PXE, in specified proportions. Photographic elements prepared with this film base have a lesser tendency to take core-set and post process curl than do elements prepared with syndiotactic polystyrene, SPS, film base.
摘要:
There is disclosed a blend of certain polyesters and polymers that are miscible with polystyrene, such as polyphenylene oxide. The blend is characterized by the presence of a compatibilizing amount of a copolymer having repeating units derived from an aromatic vinyl compound monomer and a vinylphenol monomer. The polyester is thermoplastic and is characterized in that the diacid component of the polyester includes aromatic groups and the diol component comprises at least about 20 percent by weight of a noncyclic, aliphatic diol.
