TPM Dyes

Tri phenyl metane dyes are an important group of synthetic dyes. They are are used extensively in the industries like textile, paper, food, paper cosmetics etc. TPM dyes not offer vibrant bright colors but they are also highly colorfast. TPM Dyes are ideally applied on the fabrics by using a weak acid or neutral bath that has pH level of 4- 4.5.
