Exceptional color and brightness can be obtained with the Switzer
daylight fluorescent pigments in vinyl plastisols, organosols,
calendered film, and molded articles. Other pigments, especially the
opaque kind, and large amounts of fillers cannot be used with them

The amount of fluorescent pigment required depends on the thickness of
the article or film, and on depth of color and degree of light-stability
desired. Content can range from 1% to 30%. The following table gives the
approximate minimum percentages for optimum color and light-stability:
