COMPOSITION FOR HARD-COATING FILM HAVING HIGH HARDNESS AND HARD-COATING FILM PREPARED USING THE SAME

摘要

PURPOSE: A composition for manufacturing a high hardness hard-coating film is provided to have excellent surface smoothness, hardness, scratch resistance, adhesion, and curling performance. CONSTITUTION: A composition for manufacturing a high hardness hard-coating film comprises 100.0 parts by weight of a mixture of two or more polyfunctional urethane acrylate monomers having different functional numbers; 400-600 parts by weight of a compound represented by chemical formula 1; 30-70 parts by weight of a photoinitiator; and 15-25 parts by weight of a solvent. The polyfunctional urethane acrylate monomer mixture is the mixture of a trifunctional acrylate monomer and a decafunctional acrylate monomer. A hard-coating film is manufactured by using the composition for manufacturing a hard-coating film.
