US 2023/0203314 A1 · DYE FOR MATERIAL WITH AMIDE FUNCTIONAL GROUPS AND DYEING METHOD OF USING THE SAME

Abstract

A dye for a material with amide functional groups and a dyeing method of using the same are provided. The dye includes a compound represented by Formula (I) and a solvent. Based on the total weight of the dye of 100 wt %, a content of the compound represented by Formula (I) is 40 wt % to 95 wt %. In Chemical Formula (I), R1, R2 and R3 are each independently H, —OH or —COOH, wherein at least one of R1, R2 and R3 is —OH or —COOH.
