The ballpoint pen, the felt-tip marker, and the fibre-tip pen have led to inks containing solutions of dyes in water or organic solvents such as propylene glycol, propyl alcohol, toluene or glyco-ethers. Innovations in chemistry since have added variety to ink's chemical composition. Ink properties can vary greatly in terms of thickness, color, flow, and even permanence, however they are all generally composed of three main categories of chemicals: colorants, varnishes, and additives.
