  • Tint compositions for nylon having improved fugitivity properties
    Patent number: 4102644
    Abstract: Tint compositions for nylon having improved fugitivity properties comprising an admixture of a colorant having the general formulaR{N-[(CH.sub.2 CH.sub.2 O).sub.n H].sub.2 }.sub.xwherein R is an organic dyestuff radical, x is an integer of 1 to 6, and the product of 2n times x is from about 200 to about 300, and at least 30 weight percent of a water-soluble polymeric resin. A minor effective amount of a free radical inhibitor can be incorporated into the tint compositions to retard free radical interaction between the colorant and the nylon.
