Abstract: The invention described relates to a method for the manufacture of resinous formed articles which are color tinted with dyestuffs which are normally considered to be incompatible therewith. These dyestuffs, such as certified F.D. and C Yellow No. 5, are accepted non-toxic colorants for foods, drugs and cosmetics but by themselves are normally incompatible with oils, waxes and resins. By first complexing these water soluble, resin insoluble dyestuffs with a polyhydric alcohol, such as glycerine, and subsequently the higher fatty acid ester decaglycerol tetraoleate in the presence of heat, it is possible to prepare a uniformly colored resin solution or paste which can be further cured to form a color tinted transparent plastic film or sheet useful in the packaging of foods, drugs and cosmetics.
