ABSTRACT:
Proposed is a cured silicone rubber article such as a push button switch covering member having a protective coating layer of a urethane resin-based coating composition having excellent wear resistance against rubbing and capable of giving a dry and rigid touch feeling to the finger tip of the operator of the key tops. The coated silicone rubber article is obtained by subjecting a cured base body of a silicone rubber, prior to the coating with a urethane resin-based coating composition, first to a low temperature plasma treatment and then to a coating treatment with a specific primer composition which is a mixture of an epoxy group-containing organosilane compound and an amino group-containing organosilane compound in a molar mixing ratio in the range from 1:2 to 1:5.
