<P>PROBLEM TO BE SOLVED: To provide a finely rugged structure whose appearance is prevented from deteriorating due to fingerprint stains adhering thereto. <P>SOLUTION: In the case that artificial fingerprint liquid is applied on a finely rugged structure 10 including a face layer 12 having a finely rugged structure 15 formed on its exposed surface, the difference between the reflectance rates of the exposed surface that are measured before and 24 hours after the artificial fingerprint liquid is applied on the exposed surface is 1.0% or less. It is desirable that the face layer 12 is obtained by hardening an active energy ray curable resin composition containing 60-83 mass% of a particular monomer (A), and 17-40 mass% of at least one monomer (B) selected from polyalkylene glycol mono (meth) acrylate and polyalkylene glycol di (meth) acrylate (provided that the sum of the monomer (A) and the monomer (B) is 100 mass%). <P>COPYRIGHT: (C)2013,JPO&INPIT |
