  • Hard coating composition and composition for forming a high refractive index antiblocking layer
    Patent number: 9938426
    Abstract: To provide a hard coating composition which forms a hard coat layer that has high visibility and good hardness, while having stretchability. To provide a technique which is capable of effectively preventing blocking phenomenon in a layered product such as a resin film without adversely affecting the visibility. The present invention provides a hard coating composition which contains (A) a phenolic novolac acrylate that has two or more acrylate groups and (B) an aromatic group-containing mono or poly(meth)acrylate compound that contains 1-2 mol of an alkylene oxide structure having two or three carbon atoms in each molecule. This hard coating composition contains 60-85 parts by mass of the phenolic novolac acrylate (A) and 15-30 parts by mass of the (meth)acrylate (B) per 100 parts by mass of the resin component contained in the hard coating composition.
