Abstract
Coatings particularly useful as marking inks in which an epichlorhydrin-modified polyethylenimine and an ethylene oxide-modified polyethylenimine cooperate in aqueous solution to form a composition capable of application to form deposits adherent to most materials and resistant to most organic solvents but readily removable by water.
Claims6
A composition for depositing an organic solvent-resistant, water-removable coating comprising a solution in water of from about 3.2 to about 6.9 parts by weight of an epichlorhydrin-modified polyethylenimine (I) and one part by weight of an ethylene oxide-modified polyethlenimine (II).
