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.

Hard coating composition and composition for forming a high refractive index antiblocking layer

The purpose of the present invention is to provide a transparent electroconductive laminate having extremely high visibility. A transparent electroconductive laminate in which a hard coat layer, a color difference adjustment layer, and a transparent electroconductive layer are formed in this order, wherein (1) the hard coat layer being obtained by applying and curing a hard coating composition including (A) a phenol Novolac-type acrylate having two or more acrylate groups and (B) an aromatic-group-containing mono- or poly(meth)acrylate compound having 1-2 moles of a C2 or C3 alkylene oxide structure in the molecule thereof, (2) and the color difference adjustment layer includes a cured resin component (i), and metal oxide particles (ii) having an average primary particle diameter of 100 nm or less and/or metal fluoride particles (iii); having an average primary particle diameter of 100 nm or less, where the total mass of particles (ii) and (iii) in the color difference adjustment layer is 0-200 parts by mass with respect to 100 parts by mass of the cured resin component (i).
