Ink Pigment Textile Printing Used Pigment Yellow 13

This batch of “second-hand” Pigment Yellow 13 represents degraded, surplus stock plagued by severe moisture absorption and irreversible agglomeration, making it nearly impossible to disperse effectively in ink systems without causing grit and screen blockages. The prolonged storage has compromised its chromatic intensity and purity, resulting in dull, muddy shades that lack standard vibrancy; coupled with its inherently limited lightfastness and high impurity content, this material poses a critical risk of bleeding and poor wash fastness in textile printing, rendering it a production liability.
