Provided is a resin composition for producing a coating composition excellent in appearance, abrasion resistance, and hardness of a coating film. The resin composition of the present invention includes a compound A having a branched structure which has a terminal hydroxyl group, a polyisocyanate B, and an inorganic particle C, in which the inorganic particle C has a functional group enabling reacting with a hydroxyl group or an isocyanate group on a surface thereof.

Resin composition, coating composition, and coated article

An active energy ray-curable resin composition which contains (A) inorganic oxide particles each having an organic functional group on the surface, (B) a siloxane oligomer which has at least one functional group selected from the group consisting of a (meth)acryloyl group, an epoxy group and a vinyl group, while having a weight average molecular weight of 200-3,000, (C) a polyfunctional (meth)acrylate having a specific structure, (D) a urethane (meth)acrylate having two or more (meth)acryloyl groups in each molecule, and (E) an ultraviolet absorbent.

Active energy ray-curable resin composition, resin molded article, and method for producing resin molded article

Provided are: a curable composition that makes it possible to form a cured film having excellent wear resistance and weather resistance; a laminate that is provided with the cured film; and an automobile headlamp lens. The curable composition makes it possible to obtain a cured film in which the relationship between a haze value (&#x394;Hx) that is obtained by a wear resistance test and a haze value (&#x394;Hy) that is obtained by a weather resistance test satisfies &#x394;Hy&#x2264;&#x2212;0.3 &#x394;Hx+5.0 when a cured film having a thickness of 10 &#x3bc;m is produced.

Curable composition, laminate, and automobile headlamp lens

Provided are: a resin composition with which it is possible to form a cured film having excellent weather resistance and wear resistance; and a resin molding having said cured film. An active energy beam-curable resin composition containing a radical polymerizable compound and a photopolymerization initiator (d), wherein said radical polymerizable compound contains 57-90 mass % of (a) caprolactone-modified mono- or poly-penta erythritol poly (meth)acrylate represented by formula (1) and 10-43 mass % of (b) urethane (meth)acrylate synthesized from a polycarbonate polyol having a branched alkyl structure and an average molecular weight falling within the range of 500-1000, a diisocyanate having an alicyclic structure, and a mono (meth)acrylate containing a hydroxyl group. In formula (1), each X independently represents a caprolactone-modified (meth)acryloyl group, a (meth)acryloyloxy group, or a &#x2014;OH group.
