Questions And Answer | Back Directory | [Description]
2,5-Bis (5-tert-butyl-2-benzoxazolyl) thiophene (also known as fluorescent brightener 184)1 is used as an optical brightener, which converts UV light into visible light. It is also used as a fluorescent brightener for thermoplastic resins of polyvinyl chloride, acrylic resin, polyester fiber, thermoplastic plastic, ABS, cellulose acetate fiber, paint, coating and printing ink. It is also useful in detecting the presence of thin-film electrical contact lubricants2-4.
