Abstract: Disclosed is an antibacterial and anti-shielding composition for a window film. The composition contains: 17.0 to 19.0 parts by weight of a monomer component composed of dipentaerythritol hexaacrylate and N,N-dimethylacrylamide; 0.85 to 0.95 parts by weight of any one or more liquid compounds selected from the group consisting of diphenyl(2,4,6-trimethylbenzoyl) phosphine oxide, oligo[2-hydroxy-2-methyl-1-[4-(1-methylvinyl)phenyl]propanone], 2-hydroxy-2-methylpropiophenone, and 2,4,6-trimethylbenzophenone; 0.35 to 0.40 parts by weight of 1-hydroxycyclohexylphenylketone; 0.15 to 0.20 parts by weight of phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide; 0.04 to 0.06 parts by weight of 2-propenoic acid, butyl ester; 50.0 to 78.0 parts by weight of a liquid heat-shielding agent; and 2.0 to 2.5 parts by weight of an antibacterial agent. Also disclosed are a method of producing a window film using the composition, and a window film produced thereby.
