Title:
ANTI-GLARE COATING COMPOSITION, OPTICAL LAMINATE MEMBER USING ANTI-GLARE COATING COMPOSITION, AND METHOD FOR FORMING ANTI-GLARE HARDCOAT LAYER
Document Type and Number:
WIPO Patent Application WO/2019/070074
Kind Code:
A1
Abstract:
The present invention provides an anti-glare coating composition that has excellent anti-glare and anti-sparkle properties. This anti-glare coating composition includes first, second, and third components. An anti-glare hardcoat layer that is a cured layer of the composition has fine protrusions and recesses that are formed by phase separation of the first and second components and has a prescribed surface roughness. The third component is unevenly distributed at the protrusions. The first component includes at least a polyfunctional unsaturated-double-bond-containing monomer or oligomer. The second component is an oligomer or resin that is an unsaturated-double-bond-containing acrylic copolymer and can be cured by active energy rays or the like. The third component has a prescribed average particle size and refractive index (Rf3). Rf3 and the refractive index Rfcf of a cured coating film satisfy 0.01≤|Rf3-Rfcf|≤0.23. An SP value (SP1) for the first component, an SP value (SP2) for the second component, and an SP value (SP3) for the third component satisfy SP1-SP2≥0.7 and (SP3)<(SP2)<(SP1).
