PB Dyes, also known as phthalocyanine dyes, are a class of synthetic organic compounds widely used as colorants in a variety of applications. PB Dyes have excellent properties such as high color strength, good lightfastness, and chemical stability, making them a popular choice in the textile, paper, plastic, and ink industries.
PB Dyes are typically classified into two main categories based on their chemical structure: alpha and beta phthalocyanine. Alpha phthalocyanine dyes have a blue-green hue and are commonly used in printing inks, while beta phthalocyanine dyes have a more violet-blue hue and are often used in the production of plastics and fibers.
Due to their versatility, PB Dyes have become one of the most important classes of dyes in the market. They are also considered environmentally friendly as they do not contain heavy metals and can be easily disposed of without causing harm to the environment.
