Abstract

The invention provides a transparent film-forming coating liquid for forming a transparent film having a refractive index reducing from a lower layer to a top layer, excellent light transmittance and transparency and anti-static and anti-reflection performances. The transparent film-forming coating liquid is composed of surface-treated silica type particles (A), surface-treated chain conductive metal oxide particles (B), a matrix-forming component and a solvent. An average particles size (DA) of the surface-treated silica type particles (A) is within 10-200 nm; the surface-treated chain conductive metal oxide particles (B) is formed by connecting 2-30 metal oxide particles with an average particles size (DA) being within 5-20 nm into a chain; and the metal oxide particles are chain conductive particles with a volume resistance value being 10<-2>-10<0> ohms.cm. A concentration of the surface-treated silica type particles (A) is within a range of 0.05-35 wt.% in terms of solids; a concentration of the surface-treated chain conductive metal oxide particles (B) is within a range of 0.025-25 wt.% in terms of solids; a concentration of the matrix-forming component is within a range of 0.1-42.5 wt.% in terms of the solids; and a concentration of total solids is within a range of 0.5-50 wt.%.

Description

technical field [0001] The present invention relates to a coating liquid for forming a transparent film for forming a transparent film comprising a chain-shaped conductive metal oxide particle component with a high refractive index and a substrate with a transparent film by applying once. A coating liquid containing silica-based particle components with a low rate has at least antistatic performance and antireflection performance. Especially in the transparent film, the content of the conductive component gradually decreases from the lower layer to the upper layer of the transparent film. On the one hand, the content of low refractive index components gradually decreases from the upper layer to the lower layer of the transparent film. As a result, the refractive index gradually decreases from the lower layer to the upper layer, and the light transmittance and transparency are excellent, and it has antistatic and antireflection properties. Background technique [0002] Conven...
