| titleOfInvention | NEW UNSYMMETRIC BENZOXAZOLYL (2 ') BENZIMIDAZOLYL (2' ') NAPHTHALINS, METHODS FOR THEIR MANUFACTURING AND THEIR USE AS OPTICAL BRIGHTENERS |
| abstract | New unsymmetrical benzoxazolyl-(2')-benzimidazolyl-(2")-naphthalenes are of formula (I): In the formula, A is naphthylene, opt. substd. by alkyl, halogen, esp. Cl or Br, or by an opt. functionally changed carboxy or sulpho gp. R1 is H, 1-4C alkyl opt. substd. by OH or CN, or an aryl or aralkyl gp. R2 - R9 are each H or a non-chromophoric substituent. R10 is H or alkyl. B- is a colourless aniom. n is O or 1.) (I) are colourless to light yellow and have, in soln., a strong violet to blue fluorescences. (I) are used as optical brighteners, for lacquers, synthetic fibres, e.g. of cellulose acetate, polyamides, polyolefins, PVC, polyvinylidene chloride, polyesters, esp. polyacrylonitrile, and also foils films, belts and moulded articles. (I) may also be added to detergents. In an example, 1- Benzoxazolyl-(2') -4- benzimidazolyl-(2") -naphthalene was prepd. by reacting 4- benzoxazolyl-(2') -naphthoic acid-1 with 1,2-diaminobenzene in polyphosphoric acid. |
