  • Patent number: 4396698
    Abstract: A loaded polymer latex composition is disclosed. The composition comprises an aqueous polymer latex whose dispersed phase is made up of a specified cross-linked quaternary salt polymer loaded with a specified hydrophobic substance. The latex composition can be advantageously employed as a mordant polymer in a photographic element for a color diffusion transfer process. Use of the latex improves light resistance without lowering the maximum densities of the film images.
