Disclosed are flocced mineral materials which may be utilized to prepare high temperature resistant, water resistant articles. These materials are prepared by utilizing, as a starting material, a gellable layered swelled silicate that has an average charge per structural unit that ranges from about -0.4 to -1 and which contains interstitial cations which promote swelling with a source of at least one species of multiamine derived cations.

Two:One layered silicate flocs with homogeneously intermixed polymers and a method for the compositions's preparation is described. Preferred embodiment include co-flocculated homogeneously intermixed polymer and 2:1 layered silicate. The materials are prepared by contacting a co-dispersion of polymer and silicate with a cationic flocculant.

Disclosed are compositions of flocced mineral materials combined with fibers and/or binders. These compositions may be utilized to prepare high temperature resistant, water resistant articles. These materials are prepared by utilizing, as a starting material, a gellable layered swelled silicate that has an average charge per structural unit that ranges from about -0.5 to -1 and which contains interstitial cations which promote swelling with a source of at least one species of an exchange cation that is derived from guanidine or compounds closely related thereto.

The present invention relates to magnetic toners and processes for producing them. The toner materials that are produced have the color of the magnetic material substantially obscured while still maintaining the high percentages of magnetic materials necessary for many types of magnetic printing processes. Further, the toners may be provided with a desired shade or color with dyes or pigments. The process of production preferably involves the coating of the individual magnetic particles with low-density essentially opaque polymeric particulate material having an affinity for the magnetic particles, thereby obscuring the color of said magnetic particles. The resulting coated particles may be intermixed with dyes, pigments, binders and other material as desired to produce toners which are useful for a variety of purposes, including multi-color reproduction techniques.
