Syntheses and properties of bistriazinylaminostilbene derivatives have been investigated in order to select excellent fluorescent dyes for practical use. In the synthesic experiment, change of combinations of substitution groups on the triazine ring has been made and the derivatives thus obtained were tested on their solubility, acid-resistant, property of aqueous solution and increasing of whiteness of cotton and Nylon. The result indicated that the product having a strong property of increasing of whiteness was found to be limited on a compound of one molecular condensate of sodium 4, 4′-diaminostilbene-2, 2′-disulfonate having one of each of aromatic amine residual group as a substituent group on two triazine rings.
Among the derivatives of this type of compound prepared, there was a compound having value for practical use in increasing the whiteness of Nylon.
