Abstract
A balloon is formed from a water-soluble film which mainly comprises a polyvinyl alcohol. Coloring agents as food additives are used for pigmenting the balloon. The balloon per se is soluble in water upon coming in contact with water and accordingly, it never becomes a cause of environmental pollution. The coloring agents used are those for use in foods and thus they do not become a cause of environmental pollution.
