Description

Acid Red 266 is a hydroxyl-containing polymeric dye that is used in the textile and paper industries as a colorant, pigment, or dye. It has been shown to be an efficient control agent for the polymerization of polyvinyl acetate. Acid Red 266 can also be used to form films with high light stability and good mechanical properties. The hydroxyl group present in this molecule causes it to have a polarizing effect on UV absorption. Acid Red 266 is made of particles that are soluble in water and alcohols, but insoluble in oils. This acid dye is also sensitive to heat, so it should not be exposed to temperatures over 60°C.
