Chemists at DuPont’s Parlin, New Jersey laboratory produced a pyroxylin lacquer in 1920 called Viscolac and improved upon it in the following years and renamed it Duco. In the late 1920s Dulux was developed, which was an alkyd finish and had a higher gloss finish; a matte version of Dulux was also developed. This collection is a packet of advertising and sales aids for dealers of DuPont Duco and Dulux paints and finishes.
