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&#xb0; 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.

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

A coating agent comprising 50 to 99 parts by weight of a monomer or monomer mixture (M) composed of 50 to 100% by weight of a polyfunctional (meth)acrylate monomer (m-1) having two or more (meth)acryloyloxy groups and 0 to 50% by weight of a monofunctional (meth)acrylate monomer (m-2), and 1 to 50 parts by weight of colloidal silica, wherein the colloidal silica contains colloidal silica in a narrow and long form having an average diameter of 5 to 20 nm and an average length of 40 to 300 nm in an amount of 5 to 100% by weight based on the total colloidal silica weight; and a resin molded article having a coated layer obtained by hardening this coating agent, are disclosed. This colloidal silica-containing coating agent is excellent in appearance, hardness, abrasion resistance, weather resistance, adhesion with a substrate, no need of a solvent, and the like.
