A thermosetting composition comprising: (A) a (meth)acrylate compound having a viscosity at 25&#xb0; C. of 1 to 300 mPa&#xb7;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&#xb0; C. and 10 sof 1 Pa&#xb7;s or more and 500 Pa&#xb7;s or less and a shear velocity at 25&#xb0; C. and 100 sof 0.3 Pa&#xb7;s or more and 100 Pa&#xb7;s or less.

Thermosetting composition, and method for manufacturing thermoset resin

Provided are a lubricating oil composition containing (A) a specific amide compound and (B) a metal-based detergent, wherein the content of the metal-based detergent (B) as converted in terms of metal atom is, based on the total amount of the composition, more than 300 ppm by mass and 1,000 ppm by mass or less, and having a high intermetallic friction coefficient and excellent clutch anti-shudder performance; and a lubrication method and a transmission using the composition.

Lubricating oil composition, lubrication method, and transmission

Provided is a (meth)acrylate composition containing: (A) at least one (meth)acrylate compound selected from the group consisting of a (meth)acrylate-modified silicone oil, a (meth)acrylate having a long-chain aliphatic hydrocarbon group, and a polyalkylene glycol (meth)acrylate having number-average molecular weight of not less than 400; (B) a (meth)acrylate compound to which an alicyclic hydrocarbon group having 6 or more carbon atoms is ester-linked; (C) (meth)acrylic acid or a (meth)acrylate compound having a polar group; (D) a radical polymerization initiator; and (E) a white pigment.
