A shaped product comprising a hardcoat layer, wherein the hardcoat layer is a cured product of a curable composition comprising a cationic curable silicone resin and a leveling agent, the cationic curable silicone resin comprising a silsesquioxane unit, having a monomer unit having an epoxy group in a proportion of not less than 50% by mol in a total monomer unit, and having a number average molecular weight of 1000 to 3000.

Curable composition and shaped product

Provided is a shaped article including a hardcoat layer, where the hardcoat layer has surface hardness, flexibility, and heat resistance at high levels and offers excellent workability. The shaped article according to the present invention is a shaped article including a hardcoat layer, a substrate layer, and a thermoplastic resin layer and having a curved shape. The hardcoat layer defines an outermost surface of the shaped article. The hardcoat layer includes a cure product of a curable composition. The curable composition includes a cationically curable silicone resin and a leveling agent. The cationically curable silicone resin includes a silsesquioxane unit. The cationically curable silicone resin includes an epoxy-containing monomeric unit in a proportion of 50 mole percent or more of the totality of all monomeric units and has a number-average molecular weight of 1000 to 3000.

Moulded body

Provided is a scratch self-repairing film including a hardcoat layer that has surface hardness, flexibility, and heat resistance at high levels and offers excellent workability. The scratch self-repairing film according to the present invention includes a substrate layer, a hardcoat layer on or over one side of the substrate layer, and a flexible resin layer on or over the other side of the substrate layer. The hardcoat layer includes a cured product of a curable composition. The curable composition includes a cationically curable silicone resin and a leveling agent. The cationically curable silicone resin includes a silsesquioxane unit. The cationically curable silicone resin includes an epoxy-containing monomeric unit in a proportion of 50 mole percent or more of the totality of all monomeric units and has a number-average molecular weight of 1000 to 3000.

Scratch repair film

Provided is a curable composition which can form, when cured, a cured product having high surface hardness and offering excellent flexibility and workability. The curable composition according to the present invention contains a cationically curable silicone resin, an epoxy compound other than the cationically curable silicone resin, and a leveling agent. The cationically curable silicone resin includes silsesquioxane units. The cationically curable silicone resin includes epoxy-containing constitutional units in a proportion of 50 mole percent or more of the totality of constitutional units in the cationically curable silicone resin. The cationically curable silicone resin has a number-average molecular weight of 1000 to 3000.

Curable composition, and moulded body

A sliding member includes: a metal substrate; an undercoat primer layer that is formed on a sliding surface of the metal substrate; and a resin layer that is formed on the undercoat primer layer, in which the resin layer is formed by curing a composition layer containing a bifunctional alicyclic epoxy and a polymerization initiator.
