ELECTROCONDUCTIVE LAMINATE AND TOUCH PANEL USING THEREOF

摘要

The present invention is an electroconductive laminate characterized in that the hard coat layer is formed from a hard coating composition which contains (A) a phenolic novolac acrylate having two or more acrylate groups, (B) a bisphenol structure-containing diacrylate having 2 to 4 moles of alkylene oxide structure with two or three carbon atoms in each molecule, (C) a polyfunctional acrylate having three or more acrylate groups, and (D) a polyfunctional urethane acrylate having three or more acrylate groups and an ester structure.

主权项

1. An electroconductive laminate in which a hard coat layer and an electrically conducting layer are formed on at least one surface of a polycarbonate substrate, wherein
the hard coat layer is obtained by a hard coating composition comprising(A) a phenolic novolac acrylate having two or more acrylate groups,(B) a bisphenol structure-containing diacrylate having 2 to 4 moles of alkylene oxide structure with two or three carbon atoms in each molecule,(C) a polyfunctional acrylate having three or more acrylate groups, and(D) a polyfunctional urethane acrylate having three or more acrylate groups and an ester structure, whereinthe hard coating composition comprises15 to 25 parts by mass of the phenolic novolac acrylate (A),25 to 35 parts by mass of the bisphenol structure-containing diacrylate (B),25 to 35 parts by mass of the polyfunctional acrylate (C), and15 to 25 parts by mass of the polyfunctional urethane acrylate (D), with respect to 100 parts by mass of a resin content in the hard coating composition, and wherein
the electroconductive laminate is substantially free of a resin component that may volatilize during heat treatment of the electroconductive laminate carried out at 130° C. for 2 hours.
