POWDER, METHOD FOR PREVENTING BLEEDING OF DYE, AND METHOD FOR IMPROVING DYEING PROPERTIES

摘要

[Problem] The present invention addresses the problem of providing: a powder of a resin composition comprising at least a resin and two types of dyes each having a sublimation property; a method for preventing the bleeding of the dyes from the aforementioned powder in the powder; and a method for improving dyeing properties in a dyeing method using the powder as a coloring agent. [Solution] A powder of a resin composition comprising at least a resin and at least two types of dyes each having a sublimation property, wherein the solubility of at least one of the above-mentioned at least two types of dyes in propylene glycol monomethyl ether acetate is 0.2 to 3 g/100 ml and the solubility of at least one other dye among the above-mentioned at least two types of dyes in propylene glycol monomethyl ether acetate is less than 0.2 g/100 ml.
