1. A gasket for use in a syringe so formed as to liquid-tightly and slidably contact an inner surface of an outer cylinder of said syringe,
said gasket comprising a gasket body made of an elastic body and a coating layer formed on a portion thereof which contacts at least said syringe, wherein said coating layer comprises a composition containing a silicone resin which comprises a condensate of a reactive silicone having a terminal silanol group at both terminals thereof, and wherein the condensate contains a siloxane bond derived from said silanol group, wherein said coating layer does not contain solid fine particles, wherein said composition contains an alkylalkoxysilane as a second silicone compound different from said silicone resin having said siloxane bond, an aminoalkylalkoxysilane as a third silicone compound and a glycidoxyalkylalkoxysilane as a fourth silicone compound, and said gasket has a plunger which is mounted on said gasket body or is capable of being mounted thereon. |
