Provided are a composition capable of forming a cured product with excellent hardness, scratch resistance, chemical resistance, and flexibility; and a polyisocyanate compound that can be used as a curing agent for the composition. The polyisocyanate compound is represented by Formula (1), wherein R1 to R3 are identical or different and are a group represented by Formula (1a), wherein L1 and L2 are identical or different and represent an alkylene group having from 1 to 10 carbons, m represents a number of 0 or greater, L3 represents a divalent hydrocarbon group having from 4 to 18 carbons, and X represents an isocyanate group or a blocked isocyanate group blocked with a blocking agent, where m is not simultaneously 0 for R1 to R3, and the bond with the wavy line bonds to a nitrogen atom in Formula (1). In addition, the composition contains a polyisocyanate compound and a polyacrylic polyol.
