Why was permanent marker invented?

Answer 1

A permanent marker is a type of marker pen that is used to create permanent writing on an object. Generally the liquid is water resistant, contains a solvent such as xylene, toluene, or alcohol[citation needed]and is capable of writing on a variety of surfaces from paper to metal tostone. They come in a variety of tip sizes (ultra fine to wide), shapes (chisel point, bullet tip, and wide bristle), and colors (metallic, non metallic, or ultraviolet reactive).

Like spray paint, these markers give off volatile organic compounds.

Some of the most recently made permanent markers are made from recycled plastic.[citation needed]

The permanent marker was invented in 1952 by Sidney Rosenthal.

RemovalThese markers are generally not truly permanent as, on most surfaces, they do not stain but form a surface layer that can be removed byhigh pressure cleaning or paint thinning solvents such as acetone, and they will eventually wear away over time. Some markers are designed to be long lasting, for instance by having two inks, one specialized to resist solvents, and one specialized not to fade.[citation needed] These are primarily used in graffiti and can be available in refillable form.[citation needed] A permanent marker can also be removed using a dry erase markeron certain surfaces such as a whiteboard as it contains acetone. An alcohol-based product (such as aftershave) and some paper towel is also effective in removing permanent marker. Simply apply the alcohol and wash clean with the paper towel. It should be noted that it works better on smooth, hard surfaces like polished wood, tile and linoleum.

Answer 2

Permanent markers were invented to create a writing tool that produces long-lasting, waterproof marks on various surfaces. They are commonly used for labeling, drawing, and writing on materials such as plastic, metal, and glass.
