Tinopal® OB CO is a fluorescent optical brightener/whitening agent that exhibits excellent heat resistance and high chemical stability. If Tinopal® OB CO is to be used in combination with a UV absorber, the absorption spectrum of the latter should leave an open window in the near UVA for the optical brightener. Due to the intrinsic light fastness properties of optical brigtheners, Tinopal® OB CO is recommended for indoor use only.
It is recommended for applications such as: white and pastel-tone paints where it intensifies the degree of whiteness; clear coats and overprint varnishes where it is used to mask the yellowish inherent color and also to intensify the brilliance of white and colored base coats; primer and/or topcoats where it is used as a marker to identify voids, holidays and uneven coverage; black and blue printing inks to increase their deep tone; printing inks for quick identification, security and safeguard against forgeries (i.e., bank notes); packaging inks as promotional tool or as tracer for packaging lines; manufacture of fluorescent pigments/dyestuffs to reinforce the brightness of certain shades, particularly blue ones; thermal dye diffusion paper to enhance paper whiteness; film base for photographic paper.
