Abstract: A thermosetting composition comprising: (A) a (meth)acrylate compound having a viscosity at 25° C. of 1 to 300 mPa·s with which a substituted or unsubstituted aliphatic hydrocarbon group including 6 or more carbon atoms is ester-bonded; (B) spherical silica; and (C) a white pigment, and having a shear viscosity at 25° C. and 10 s?1 of 1 Pa·s or more and 500 Pa·s or less and a shear velocity at 25° C. and 100 s?1 of 0.3 Pa·s or more and 100 Pa·s or less.

Abstract: A functional layer, such as a light emitting layer, of an organic electron device, such as an organic electroluminescence device, is provided. The function layer includes a small amount of a charge injection auxiliary material capable of enhancing charge injection properties. The charge injection auxiliary material comprises a stilbene, distyrylarylene or tris(styrylarylene) compound and is employed in an organic electron device wherein a positive-hole transporting organic functional layer is subjected to positive-hole injection from an external layer by incorporating the charge injection auxiliary material in the functional layer. The organic electroluminescence device provided by the present invention has a lowered applied voltage, an enhanced luminous efficiency and a prolonged service life.

Abstract: Overbased sulfurized alkaline earth metal phenates which are oil soluble, excellent in detergency dispersancy and have high base value, and an effective process for production of said overbased sulfurized alkaline earth metal phenates under conditions providing less sludge and less raw material recovery, and further a lubricating oil additives containing said overbased sulfurized alkaline earth metal phenates as a main ingredient and a lubricating oil composition which comprises said lubricating oil additive compounded in a lubricating oil are disclosed. Since the resulting overbased sulfurized alkaline earth metal phenates have high base value and excellent oil-solubility, they can be effectively utilized as lubricating oil additives.
