    • The present invention provides fluorine-containing boric acid composite particles comprising a condensate of boric acid and a fluorine-containing alcohol represented by the general formula:

              R F -A-OH     [I]

      wherein R F is a perfluoroalkyl group having 6 or less carbon atoms, or a polyfluoroalkyl group, in which some of the fluorine atoms of the perfluoroalkyl group are replaced by a hydrogen atom or atoms, and which contains a terminal perfluoroalkyl group having 6 or less carbon atoms and a perfluoroalkylene group having 6 or less carbon atoms; and A is an alkylene group having 1 to 6 carbon atoms. The fluorine-containing boric acid composite particles may also be a condensate of boric acid, the said fluorine-containing alcohol, and an alkoxysilane at a molar ratio of 1.0 or less based on the fluorine-containing alcohol. These fluorine-containing boric acid composite particles has excellent adhesion to inorganic substrates, and the like.
    • 本发明提供含有由通式:RF-A-OH [I]表示的硼酸和含氟醇的缩合物的含氟硼酸复合颗粒,其中RF是具有6个或更少碳原子的全氟烷基, 或其中全氟烷基的一些氟原子被一个或多个氢原子取代并且包含具有6个或更少碳原子的末端全氟烷基和具有6个或更少碳原子的全氟亚烷基的多氟烷基; A是具有1至6个碳原子的亚烷基。 含氟硼酸复合粒子也可以是相对于含氟醇为1.0以下的摩尔比的硼酸,上述含氟醇和烷氧基硅烷的缩合物。 这些含氟硼酸复合粒子对无机基材的密合性等优异。
