PROBLEM TO BE SOLVED: To provide a surface treatment sheet for a board of a pinball game machine, which does not generate whitening and cracking when driving a nail, while having excellent retainability of the driven nails, causing neither peeling nor lifting in NC cutting with excellent cutting workability, and restraining the occurrence of static electricity by applying antistatic treatment. SOLUTION: The sheet for the board of the pinball game machine is bonded onto a board face of the machine, and includes a transparent resin sheet and an antistatically-treated layer formed on at least a face side of the resin sheet contacting the board face of the machine. The resin sheet is formed of a transparent methacrylic resin sheet containing multilayer structural particles consisting of acrylic rubber with a rigid layer, a soft layer and the outermost rigid layer. The antistatically-treated layer includes a layer consisting of a mixture of poly-3,4-ethylene-dioxithiophene and polystyrene sulfonic acid. COPYRIGHT: (C)2011,JPO&INPIT |
