ANTI-BLOCKING HARD COATING COMPOSITION HAVING EXCELLENT TRANSMISTANCE AVAILABLE MUTI-LAYER COATING AND MANUFACTURING METHOD OF THE SAME

摘要

The present invention relates to a manufacturing method of an anti-blocking hard coating composition having excellent transparency capable of multilayer coating, which comprises: 1-40 wt% of a dispersion sol of inorganic particles having an average diameter of 10-100 nm; 10-30 wt% of a photocurable multifunctional monomer; 1-20 wt% of a photocurable oligomer; 1-5 wt% of a photoinitiator; 1-10 wt% of a hydrophilic acrylic copolymer to reduce a water contact angle; and 30-60 wt% of a dispersion solvent. According to the present invention, the anti-blocking hard coating composition has excellent optical properties such as permeability and haze by using a dispersion sol of inorganic particles having a grain size of 100 nm or less and is capable of multilayer coating due to a water contact angle as low as 60-70°C by using a hydrophilic acrylic copolymer.
