    摘要： A photographic imaging element is disclosed comprising a support having on a front side thereof a silver halide imaging layer and an outermost protective overcoat layer comprising a film-forming binder, and on the backside thereof an outermost protective backcoat layer comprising a film-forming binder; the protective overcoat and backcoat layers each comprising a lubricant present in an amount of at least 5 mg/m2 and permanent matting agent having a Tg of at least 40° C. and an average particle size of from about 0.5 to about 3 micrometers in an amount of at least 1 mg/m2; and at least one of the protective overcoat layer or the protective backcoat layer further comprising crosslinked elastomeric polymer matte particles, wherein the crosslinked elastomeric polymer matte particles have a Tg of 20° C. or less, an average particle size of at least 90% of or greater than that of the permanent matting agent particles having a Tg of at least 40° C. in the protective layer in which the crosslinked elastomeric matte is included, and are present in the protective overcoat layer or protective backcoat layer in an amount which is (i) at least 1 mg/m2 and (ii) less than the total level of permanent matting agent particles having a Tg of at least 40° C. in the protective overcoat and backcoat layers combined. Imaging elements comprising highly lubricated protective outermost layers in accordance with the invention advantageously provide increased scratch and wear resistance, while the presence of relatively low Tg crosslinked elastomeric matte particles in combination with higher Tg permanent matte particles has been found to increase the coefficient of friction of the layer in which they are included to provide good manufacturability of the imaging element while also maintaining wear and other desired film performance properties.

    摘要： The present invention relates to a process for synthesizing a particulate copolymer comprising: providing a reaction mixture comprising a reaction medium, a polymerization stabilizer, a water-insoluble ethylenically unsaturated monomer and an ethylenically unsaturated monomer containing hydrophilic functionality, said reaction mixture having a viscosity value of at least 10 cps measured at 40null C., and polymerizing the water-insoluble ethylenically unsaturated monomer and the ethylenically unsaturated monomer containing hydrophilic functionality. The polymerization reaction is preferably conducted at a temperature lower than 100null C. and activated by a polymerization catalyst. The resulting particulate copolymer dispersion comprises copolymer particles showing a weight average diameter size in the range of microns and absence of defects, such as coagulant or agglomerates. The present invention also provides a dispersion of a particulate copolymer obtained by using the process described above and a photographic material comprising a support and at least one layer containing a particulate copolymer obtained by using the process described above. The photographic material presents improved physical and optical performance.
