There is provided an ultraviolet curable resin composition for a self-lubricating liner, including: a (meth)acrylate compound having an isocyanuric acid ring; at least one of (meth)acrylate having a phosphoric acid ester group and (meth)acrylate having a silane group: a polythiol compound; and a polytetrafluoroethylene resin as a solid lubricant.

Free radical-curing (meth)acrylate resins contain stabilizers and acidic adhesion promoters. The (meth)acrylate resins are characterized by particularly high storage stability, even at relatively high temperatures, and a concomitant increase in the activity of the accelerator present in the (meth)acrylate resin. The special stabilizers increase the storage stability, give rise to a rapid cure rate, and make the curing properties insensitive to the acidic adhesion promoters present alongside them. This makes it possible for very good adhesion to a wide variety of materials and thus a broader field of use.
