Abstract
Abstract A method for the manufacture of a colored nonfogging article, which comprises bringing a nonfogging substrate containing a surfactant into contact with a dyeing solution containing a surfactant, a solvent and a coloring material, said surfactant being contained in the dyeing solution in an amount within the range of 20 to 100% by weight based on the total amount of the surfactant and the solvent.
