Abstract
A relatively uniform thin coating of a solid phenolic reactant can be applied to a paper base by contacting said paper base with a thin film of a solution consisting essentially of said phenolic reactant in a volatile organic solvent and immediately evaporating said solvent and, unexpectedly, said phenolic reactant is retained essentially completely on the contacted surface of the paper base. Thusly applied, it has been found that well defined colored marks are formed on the surface of the paper base on marking the surface with a colorless marking ink.
