Provided is a nonaqueous ink composition with which high recovery from cleaning and surface drying on a substrate can both be achieved even if the nonaqueous ink composition contains a white pigment or a bright pigment. This nonaqueous ink composition contains a coloring material and an organic solvent and is to be ejected by means of an inkjet method, wherein the coloring material contains a white pigment or a bright pigment, and the organic solvent contains the organic solvent A below. Organic solvent A: at least one substance selected from the group consisting of alkylamide-based solvents (a1) and cyclic amide-based solvents (a2).

Provided are: a surface protection layer composition having excellent damage resistance, and followability with respect to expansion and contraction of an elastic base material; and a decorative body using the same. This surface protection layer composition includes a silicone-modified (meth)acrylate-based resin having a glass transition point (Tg) of 0°C or less, and a carbonate-modified urethane resin. The surface protection layer composition is used to configure a surface protection layer for protecting: an elastomer base material, or a base material having a Young's modulus of 0.001MPa to -30MPa inclusive; and the surface of the decorative layer which is a cured film of an ink composition formed on the base material. Thus, adhesion to the decorative layer is excellent, and with respect to expansion and contraction of the base material, followability, and damage resistance, and the like, are excellent.
