Description
Though patented in 1888, ballpoint pens only became popular in 1945 after a viscous, smooth-flowing ink was formulated by Franz Seech in California. This ballpoint ink had a drying oil mixed with a dye (40-50%) and resin. Drying oil inks cured when exposed to air. In the 1950s, fast drying glycol inks were introduced which cured by solvent evaporation. Since that time many different formulations have been used for ballpoint inks; components may include surfactants and plasticizers. Some inks are sensitive to solvents and may contain fugitive dyes.
