Based on synthesis technology developed by Archroma, DIRESUL EVOLUTION BLACK LIQ delivers an overall impact reduction to 57%*, measuring its effect on human health, ecosystems and resources compared to standard Sulfur Black 1 liquid. Unlike traditional synthesis processes, it does not produce any ammonia, sodium salts waste or liquid effluents, and water consumption in the synthesis process is reduced by 73% for massive savings. The new DIRESUL dyestuff, when adopted with the full Archroma coloration system, delivers a new black color with on-tone wash-down effect and cleaner effluent at the mill.

Textil Santanderina and Archroma previously collaborated to produce Textil Santanderina’s aniline-free** indigo denim collection with the use of DENISOL® PURE INDIGO.

Huntsman sued Jiangsu Jinji Industrial Co., Ltd. and Taixing Jinyun Dyestuff Co., Ltd. for infringing the above mentioned Chinese Patents at the Beijing Intellectual Property Court by using Huntsman’s patented technology in six black dyestuff products. Huntsman is seeking substantial damages and an injunction against further infringement.  Huntsman is also seeking substantial damages and an injunction against further infringement in a separate lawsuit against Zhejiang Longsheng Group Co., Ltd., Zhejiang Keyong Chemical Co., Ltd., and Shanghai Colva Dyestuff Industry Co., Ltd. This matter is currently being heard before the High People's Court, Shanghai.  In earlier decisions, both the Shanghai Intermediate People’s Court and the Shanghai High People’s Court ruled that Shanghai Colva Dyestuff Industry Co., Ltd. had infringed Huntsman’s Chinese Patent No. ZL00106403.7 by manufacturing and selling Colvazol Super Black LC-G and Colvazol Super Black LC-R dyes.

Rohit Aggarwal, President of Huntsman Textile Effects said: “We are very pleased with the PRB’s decision which demonstrates the State Intellectual Property Office’s commitment to steadfastly uphold intellectual property rights in China which protect valuable and advanced technology. This encourages companies like Huntsman to continue to invest in research and development in our aim to bring cutting-edge innovation to the textile industry. Huntsman will vigorously pursue those who are infringing our intellectual property rights to stop the unlawful infringement and pursue full compensation for our losses”.
