FYI - The name YUPO was derived from the names of the parent companies, formerly Mitsubishi Petrochemical (Yuka in Japanese) Co., Ltd (presently Mitsubishi Chemical Corporation) and Oji Paper Co., Ltd, thus forming a "paper bridge" between the two. 'YUPO' is always capitalized, too. Cheap Joe says it's pronounce like 'You Poor' without the 'r' on the end. Painting on YUPO is a blast!
