NOVELTY - A (meth)acrylic-type resin composition comprises polyfunctional (meth)acrylate (A) having bisphenol structure, polyfunctional (meth)acrylate (B), monofunctional (meth)acrylate (C), photoinitiator (D), and water-absorbing polymer (E). The component (D) contains oxy-phenyl-acetic acid-2-(2-oxo-2-phenyl-acetoxy-ethoxy)-ethyl ester or oxy-phenyl-acetic acid-2-(2-hydroxy-ethoxy)-ethyl ester. The polymer (E) is crosslinking-type polyacrylate, isobutylene or maleate-type polymer, polyvinyl alcohol or polyacrylate-type polymer, or crosslinking-type carboxymethylcellulose.    USE - (Meth)acrylic-type resin composition is used for adhesive agent used for attaching and detaching adhesive materials used for manufacture of touch-sensor glass (all claimed) used for display electrode of e.g. liquid crystal display device and touchscreen, and window material of solar cell, and as antistatic film. Uses include but are not limited to construction material, electric and electronic component, motor vehicle component, office supplies, and household products.    ADVANTAGE - The (meth)acrylic-type resin composition has excellent adhesiveness, heat resistance, and peelability.    DETAILED DESCRIPTION - A (meth)acrylic-type resin composition comprises polyfunctional (meth)acrylate (A) having bisphenol structure, polyfunctional (meth)acrylate (B), monofunctional (meth)acrylate (C), photoinitiator (D), and water-absorbing polymer (E). The component (D) contains oxy-phenyl-acetic acid-2-(2-oxo-2-phenyl-acetoxy-ethoxy)-ethyl ester or oxy-phenyl-acetic acid-2-(2-hydroxy-ethoxy)-ethyl ester. The polymer (E) is crosslinking-type polyacrylate, isobutylene or maleate-type polymer, starch or polyacrylate-type polymer, polyvinyl alcohol or polyacrylate-type polymer, or crosslinking-type carboxymethylcellulose. The composition contains 5-25 parts mass component (A), 5-25 parts mass component (B), and 40-80 parts mass component (C) with respect to 100 parts mass component (A), component (B), and component (C). INDEPENDENT CLAIMS are included for the following:    (1) adhesive agent, which contains the (meth)acrylic-type resin composition;    (2) adhesive material, which contains the adhesive agent;    (3) attachment and detachment method, which involves attaching base materials by irradiating visible ray or ultraviolet-ray having energy of 1-10000 mJ/cm2 at wavelength 365 nm on the adhesive agent, and detaching base materials by irradiating visible ray or ultraviolet-ray having energy of 300-150000 mJ/cm2 at wavelength 365 nm on the adhesive agent; and    (4) manufacture of touch-sensor glass, which involves bonding electroconductive film on translucent hard substrate using the adhesive agent, and forming a predetermined pattern in the surface contrary to the bonding surface.
