ABSTRACT:
Magnetic paint or ink additives are formulated from ferromagnetic particles, preferably iron powder, having a mixed particle range of from about 0.01.mu. to about 297.mu., and preferably to about 250M and more, preferably from about 0.01.mu. to about 37 to 44.mu.; 6 to 20.mu. particles are used in one latex-based embodiment. Preferred additives are formulated by blending the particles with a surfactant, a surfactant mixture, or a surfactant and alcohol mixture in amounts sufficient to suspend the particles; a polyvinyl acetate polyer is used in one embodiment. The additives may be blended with any oil-, latex-, or lacquer-based paint, ink, or coating to form a magnetic paint or coating having a viscosity substantially similar to the paint or ink containing no particles and/or additive. Surfaces such as paper, cloth, wood, wallboard, sheet rock, foam, foam board, plywood, plastic, fiberboard, and the like so coated may be cut with conventional woodworking tools, scissors or knives.
