发明名称 Photographic elements having hydrophilic colloid layers containing hydrophobic ultraviolet absorbers uniformly loaded in latex polymer particles
摘要 This invention is directed to photographic elements having hydrophilic colloid layers containing loaded particles of from 0.02 to 0.2 micron in average diameter consisting essentially of a loadable polymer, with greater than 2 percent by weight of the polymer being derived from monomers capable of forming water soluble homopolymers. A hydrophobic photographic dye, coupler, developing agent or ultraviolet absorbing compound is loaded into and distributed through the particles. The weight ratio of the hydrophobic photographic dye, coupler, developing agent or ultraviolet absorbing compound to the loadable polymer is from about 1:4 to 3:1.
