The invention provides apparatus for grinding comprising a generally cylindrical vessel containing grinding media, extending into said cylindrical vessel an agitator rotatable about its shaft and having pegs extending generally perpendicular to said shaft wherein said pegs extend within about 1 to about 3 mm of said vessel and wherein the diameter of said vessel is between about 10 and about 20 mm.

Micro media mill and method of its use

Imaging elements, such as photographic, electrostatographic and thermal imaging elements, are comprised of a support, an image-forming layer and an electrically-conductive layer comprising a film-forming hydrophilic colloid having dispersed therein both electrically-conductive fine particles and pre-crosslinked gelatin particles. The combination of hydrophilic colloid, electrically-conductive fine particles and pre-crosslinked gelatin particles provides a controlled degree of electrical conductivity and beneficial chemical, physical and optical properties which adapt the electrically-conductive layer for such purposes as providing protection against static or serving as an electrode which takes part in an image-forming process.

Imaging element comprising an electrically-conductive layer containing

A process for preparing a uniform aqueous dispersion of titanium dioxide, gelatin, polymer beads and other components of a reflective binder layer for a photographic paper is disclosed. The process comprises combining all the components without regard to the creation of aggregates and then passing the entire mixture through a media mill to form a uniform dispersion.
