Acrylic resin, resin boards, transparent electrode boards for touch panels, touch panels, and processes for production of them

摘要

A method of producing an acrylic resin plate, comprising a step of adding 0.001 to 1 part by weight of a polymerization initiator having 10 hours half life temperature of 80° C. or more and 0.015 to 0.2 parts by weight of cyclohexadiene or terpenoid-based compound into 100 parts by weight of a mixture composed of an alkyl methacrylate having a C1-4 alkyl group and a poly-functional (meth)acrylate to give a polymerizable mixture, and a step of polymerizing said polymerizable mixture; an acrylic resin comprising 3 to 30 wt % of an alkyl methacrylate unit having a C8-20 alkyl group, 2 to 35 wt % of a mono-ethylenically unsaturated monomer unit containing an alkyl methacrylate unit having a C1-4 alkyl group and 35 to 95 wt % of a poly-functional (meth)acrylate unit; an acrylic resin plate made of the resin and production process the same, and a transparent electrode plate for touch panel and a touch panel having them.
