An object of the present invention is to provide an antibacterial sheet which is particularly extremely effective for preventing cloudiness or dew condensation and can prevent or inhibit the bacterial multiplication, an antibacterial coat, a laminate, and an antibacterial solution. The antibacterial sheet of the present invention has a support and at least one antibacterial layer disposed on the support, in which the antibacterial layer contains a binder and at least one kind of an antibacterial agent, and a water contact angle of only the binder is equal to or less than 20.

A method for depositing a silicon dioxide layer on a combustible and/or, in particular easily, inflammable carrier material (2, 2) for the formation of a package, in particular suitable for foodstuffs, with the following steps, in particular with the following sequence: coating of the carrier material with a silicon dioxide precursor solution prepared by dissolving an oligomeric, silicate, preferably a silicic acid tetramethyl ester homopolymer, in a solvent, said silicon dioxide precursor solution having a water content less than 5 vol. %, and hardening of the silicon dioxide precursor solution and thus forming the silicon dioxide layer on the carrier material in an at least partially vaporous ammonia atmosphere at: a temperature between 5 C. and 30 C. and/or a pressure between 900 MPa and 1200 MPa.

The present invention relates to an anti-reflective coating composition, to an anti-reflective film using the same, and to a method for manufacturing the anti-reflective film, wherein the anti-reflective coating composition can form a coating layer having a low refractive index. More particularly, the present invention relates to an anti-reflective film and to a method for manufacturing same, wherein the reflectance of the anti-reflective film is minimized by using an anti-reflective coating composition comprising a siloxane compound prepared by reacting organosilane, which has a fluoroalkyl group and alkoxy silane, as a binder to form a coating layer. The anti-reflective film using the anti-reflective coating composition has excellent anti-reflective effects. Thus, it is expected that the present invention can be applied to various display devices such as those which include touch films.

Disclosed herein is an inventive low-temperature curable antireflective (AR) coating produced by a single layer sol gel deposition process comprising a low-temperature curing step, whereby temperatures well below 100 C. for under 8 hours result in highly robust AR coatings having excellent transmittance and abrasion resistance. Optical, mechanical and chemical properties may be tuned by adjustment of the formulation of the wet coating solution. In this way, the inventive AR coating is able to provide enhanced mechanical and moisture resistance, as well as superior optical performance that can be optimized to suit a particular environment. The innovation advantageously enables applying AR coatings to substrates installed in the field, allowing passive heating of the substrate by sun exposure to provide the heat for curing the inventive coatings outdoors.
