ACRYLIC RESIN, RESIN BOARDS, TRANSPARENT ELECTRODE BOARDS FOR TOUCH PANELS, TOUCH PANELS, AND PROCESSES FOR PRODUCTION OF THEM

摘要

A process for the production of acrylic resin boards by polymerizing and curing a polymerizable mixture which comprises 100 parts by mass of a mixture comprising an alkyl methacrylate wherein the alkyl has 1 to 4 carbon atoms and a polyfunctional (meth)acrylate, 0.001 to 1 part by mass of a polymerization initiator having a ten-hour half-life temperature of 80°C or above, and 0.015 to 0.2 part by mass of cyclohexadiene or a terpenoid; an acrylic resin comprising 3 to 30 % by mass of alkyl methacrylate units wherein the alkyl has 8 to 20 carbon atoms, 2 to 35 % by mass of monoethylenically unsaturated monomer units comprising alkyl methacrylate units wherein the alkyl has 1 to 4 carbon atoms, and 35 to 95 % by mass of polyfunctional (meth)acrylate units; resin boards made from this resin and a process for the production thereof; and transparent electrode boards for touch panels and touch panels, made by using the above resin boards.
