Abstract

PURPOSE: To prepare a transparent article having improved anti-fogging properties and surface hardness, by copolymerizing a methacrylate or acrylate having one or more alcoholic hydroxyl groups with a polyfunctional (meth)acrylate and (meth)crylates other than those described above.
CONSTITUTION: A monomer mixture comprising 20W80wt% of a methacrylate or acrylate having one or more alcoholic hydroxyl groups, 20W80wt% of a polyfunctional (meth)acrylate, and 0W60wt% of (meth)acrylates other than those described above is copolymerized at a low temperature. After the copolymerization is completed, the molded resin article is annealed for a time necessary to remove the strain. The article thus obtained has improved anti-fogging properties, surface hardness, and durability for a long time.
