Applications
UsesDirect Red 243 is mainly used for dyeing and direct printing on cotton, viscose, and other cellulosic fiber fabrics, as well as silk. It has excellent lightfastness and good dye uptake, but poor migration properties and sensitivity to salt. It is especially suitable for one-bath, one-step dyeing of polyester-cotton and polyester-viscose blended fabrics. It can also be used for dyeing wool fabrics and can be blended with yellow, orange, red, and brown dyes. It can also be used to manufacture lake pigments.
