The surface-modified nanodiamond (20) includes a ND particle (21), which is a nanodiamond particle, and a silane coupling agent (22). The silane coupling agent (22) has a (meth)acryloyl-containing organic chain and is bonded to the ND particle (21). The resin composition (X) is suitable for forming a nanodiamond-dispersed cured resin portion having both high transparency and high scratch resistance. An optical element according to the present invention has a light-transmitting region and includes a cured resin portion, which is a cured product of the resin composition (X), in at least part of the light-transmitting region. The optical element is advantageous for actually providing an optical element including a cured resin portion or cured resin layer having both high transparency and high scratch resistance.

The present invention provides a synthetic resin composition from which a combustion residue produced by combustion is rigid. The synthetic resin composition of the present invention is configured such that the strength of the combustion residue of the composition after combustion in an atmosphere of 800° C. for 20 minutes is 0.5 N/mm.sup.2 or more. Thus, the combustion residue produced by combustion is very rigid. The combustion residue is capable of reliably holding a state where a joint part is filled therewith and clogged even during a fire, preventing flames from passing through a sealing part such as the joint part, and imparting excellent fire-proof performance to a wall part of a building construction.

A method for producing a rubber wet masterbatch comprises step (i) of producing a slurry solution by dispersing carbon black in a dispersing solvent in the presence of an inorganic filler, step (ii) of producing a slurry-containing rubber latex solution by mixing the slurry solution with a rubber latex solution, and step (iii) of producing a rubber wet masterbatch by solidifying and drying the slurry-containing rubber latex solution. The inorganic filler has a Mohs hardness of 5 or more, and in the step (i), the amount of the inorganic filler added is less than 50% by mass where the amount of the carbon black added is 100% by mass.
