I recently stumbled over a U S Patent that, I am quite sure, reveals the essence of Kykem's Hi Spot Blue's original formula. U S Patent 2396667 A was issued to Leon Adler of St. Louis in 1946, almost five years after its filing date.
Other documents, including other patents, suggest that Leon Adler was a principal of Dyestuffs and Chemicals Company -- also of St. Louis -- a manufacturer of dyes, including yellow dye for coloring margarine at home.
(Some of you may remember that, back when Dykem was an independent company, Hi Spot was offered in a whole rainbow of colors.)
