METHOD FOR SUPPRESSING AGGLOMERATION OF POWDER

摘要

PROBLEM TO BE SOLVED: To provide a method for suppressing powder agglomeration in powder of a resin composition comprising at least a resin and two types of dyes.SOLUTION: There is provided a method for suppressing powder agglomeration in powder of a resin composition comprising at least a resin and two types of dyes, wherein at least one of the two types of dyes is a disperse dye or an oil-soluble dye having a total Hansen solubility parameter of 25 to 40 MPa1/2. The method for preventing powder agglomeration suppresses powder agglomeration even when heated at a high temperature.
