Basic Dyes

Basic dyes is those dyes which in aqueous solution yield colored cations. This class of dyes is known as their brilliant hues, some of them being fluorescent. Unfortunately its brilliance is not matched by their fastness. Because of their poor fastness properties, particularly to light. manufacturers as well as suppliers of basic dyes, retained to small extent for dyeing where brightness is all important.Basic dyes yellow 2 to 40, orange 2, red 1 to 18, violet 1 to 16, blue 1 to 26, green 1 to 4, brown 1 to 4 ranges as per the specification and instructions of clients. Colorants liquid basic dyes are water soluble, but in most cases solution is facilitated by pasting the dye with acetic acid and water. Most dye baths require addition of acetic acid and it is often convenient to use part of this requirement for the above pasting process. Since solubility is not generally of high order, the availability of some dyes in liquid form is an additional aid to dye bath preparation.
