Abstract: C.I. Disperse Yellow 54 and 64 are important yellow dyestuffs of the quinophthalone type used in coloring synthetic fibers, particularly polyamide, polyester, acrylic and acetate fibers at boiling temperature conditions. Yellow azo dyestuffs of the hydroxypyridone type, e.g., C.I. Disperse Yellow 114, 180 227 and 230 have found widespread application in the high-temperature dyeing of such synthetic fibers. It has now been found that improved tinctorial results on these synthetic fiber materials can be obtained by applying a dyeing composition derived from these yellow coloring means and comprising a mixture of 70-90 parts by weight of one or more dyestuffs of the C.I. 54 and 64 type with 5 to 30 parts by weight of an azo dyestuff of the hydroxypyridone type. These improved dyestuff compositions exhibit superior leveling, high tinctorial strength or color build-up, high dyebath exhaustion and deep shade dyeing over the individual components.

Abstract: There is described a process for producing, in a continuous manner, a gradient dyeing across the width of a long strip of a plastic sheet and an apparatus used therefor. In a preferred embodiment of the invention, the orientation of the plastic strip is maintained substantially constant during the passage through a dye bath, and the dye liquid level is repetitively varied by use of a liquid level control means. This invention is particularly useful for making gradient-dyed plastic sheets which in turn are used for making sunglass lenses.
