    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 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.
