Abstract

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 (ΔHx) that is obtained by a wear resistance test and a haze value (ΔHy) that is obtained by a weather resistance test satisfies ΔHy≤−0.3 ΔHx+5.0 when a cured film having a thickness of 10 μm is produced.
