Description

technical field

[0001] The invention relates to an organic dye, in particular to an X-type reactive light-fast red azo dye. Background technique

[0002] Because of their bright color, wide color spectrum, excellent fastness, simple application process and low price, reactive dyes have developed into a type of dye with the highest utilization rate for natural fiber dyeing, and it is also a type of dye with the fastest development in recent years. However, during the application process of reactive dyes, the shortcomings of low dye utilization rate, wet rubbing fastness of dyed fabrics and relatively low light fastness of light-colored varieties are also exposed. How to overcome these shortcomings of reactive dyes has become a key topic in the research and development of reactive dyes. Contents of the invention

[0003] The object of the present invention is to provide a kind of X-type reactive light-fast red azo dye, which has better photo-oxidation resistance, and can ma...
