[1] Previously, lacquer thinners frequently contained alkyl esters like butyl or amyl acetate, ketones like acetone or methyl ethyl ketone, aromatic hydrocarbons like toluene, ethers such as glycol cellosolves, and/or alcohols.
[2] Modern lacquer thinners increasingly have to comply with low-volatile organic compounds (VOC) regulations.
Often, these formulations consist mostly of acetone and other simple ketones with very small quantities of aromatic solvents.
[3] Paints that dry by simple solvent evaporation and contain solid binders are known as lacquers.
When the solvent in lacquer paints evaporates, a solid layer remains.
