A new inorganic pigment, discovered as the result of an accident, is now reaching the market place and will shortly be added to the Colour IndexTM.
The pigment is a brilliant blue, known as “YInMn” blue. It’s based on an oxide made of Yttrium(Y), Indium (In) and Manganese (Mn). The YInMn name is shorthand for that. The pigment will be used in a wide range of coatings and plastics.

‘Clean and Green Garment Processing’, the SDC EC organised seminar was attended by 110 delegates comprising processors, brand/retailers, entrepreneurs, special guests, faculty and students. The event covered the challenges faced by the dyehouse in optimising water for the coloration of textiles and the role of the retailer. A panel discussion on “Who Pays?” followed with participation of representatives from industries including Atul Ltd, Archroma, MIDC, Brand Aniket, Wash-n-Wear and Spykar Jeans.

Old dyes? Just look in the Colour IndexTM and you may be surprised by how many dyes were first synthesised and manufactured in the nineteenth century. And, maybe, surprised again by realising how many of these dyes were never been manufactured on any significant scale, or were soon superseded by superior products, or were for various reasons abandoned as industrial colorants.
