An antireflective coating composition includes a hydrolytic condensate (C1) of alkoxy silane (C11) and fluoric alkoxy silane (C12); a particle-type metal fluoride (C2) with a refractive index of 1.40 or less; and a liquid dispersion-enhancing chelating agent (C3). A coating film to which the above composition is applied controls refractive index, surface energy, film strength and so on, so it ensures excellent antireflective characteristic, excellent scratch resistance, good erasure of liquid stains such as fingerprints, and particularly excellent dust removal, so it may be usefully applied to an outermost layer of a front surface of a display regardless of kind of a display substrate or presence of an additional coating layer.

Antireflective coating composition with stain resistance, antireflective coating film using the same, and its manufacturing method

A coating composition for antireflection that includes a low refraction-thermosetting resin having a refractive index of 1.2 to 1.45, a high refraction-ultraviolet curable resin having a refractive index of 1.46 to 2, and an ultraviolet absorber; an antireflection film manufactured using the coating composition; and a method of manufacturing the antireflection film. The antireflection film has excellent abrasion resistance and antireflection characteristic. Further, since the antireflection film can be manufactured in one coating process, it is possible to reduce manufacturing cost.

Coating composition for antireflection with resistance and antireflection characteristic and antireflection film prepared by using the same

An antireflective coating composition includes a photopolymerizable acrylate monomer (C1); a particle-type metal fluoride (C2) with a refractive index of 1.40 or less; a photopolymerization initiator (C3); and at least one liquid dispersion-enhancing chelating agent (C4) selected from the group consisting of Mg(CFCOO), Na(CFCOO), K(CFCOO), Ca(CFCOO), Mg(CFCOCHCOCF)and Na(CFCOCHCOCF). This composition ensures good mechanical strength, excellent adhesion to a substrate, short curing time by UV curing, prevention of dust attachment, good erasure of stain, good dust removal and good scratch resistance, so it is usefully for making an antireflective coating film of a display.

UV-curable antireflective coating composition, antireflective coating film using the same, and its manufacturing method

The present invention relates to a coating composition for forming an anti-reflective coating layer for a display device, comprising a fluorinated silane with low surface tension, a conductive polymer with antistatic properties, water, and a solvent. Thus, the coating film of the present invention prepared by coating the composition has high anti-reflection, excellent stain resistance to liquid-phase stains such as fingerprints and the solid-phase stains such as dust by controlling the refractive index, surface energy, and conductivity, and thus can be usefully applied to the outermost side of a display device, regardless of the type of substrates such as a Braun tube or a flat display film and the presence of other coating layers such as a hard coating layer and an anti-glare coating layer.
