http://www.madehow.com/Volume-3/Ballpoint-Pen.html for history, ingredients, etc. of pens "permanent ink, like the classic Sharpie, contains three main ingredients: a dye (solvent) and resin (polymer). For permanence, color pigments of choice (as opposed to dyes). Pigment dyes do not go and do not bleed through paper no. Odor (until 1990) markers were unpleasant solvents former organic chemicals such as xylene. Today the solvent of choice is alcohol (ethanol or isopropanol), which is more ecological and feeling better, but evaporates quickly to prevent further sale stains, etc. Finally, there is a resin or polymer is added as a "binder" that promotes adherence … Resin permanent is not permanent, unless it sticks like glue to most surfaces it is written. The resin forms a film (once that the alcohol evaporates) which allows the ink to write smoothly and uniformly on any surface (smooth or rough), while serving as the glue to the pigment. Resins are of all shapes and sizes, usually acrylic polyurethane resins are used (as used in paints for the house). "of http://www.madsci.org/posts/archives/2005-08/1125342426.Ch.r.html
