Description and Uses

Fast Red ITR is a nonlinear optical material and can be used in alkaline phosphatase histochemistry. In addition, it is used for dyeing and printing cotton and viscose fabrics. It is the only light pink fast dye among ice dyes and can replace soluble reduced pink IR (soluble indigo pink IR) and bright red base. It can also be used for the printing and dyeing of silk and nylon fabrics.
