 production of the single-coat and multicoat coating systems of the invention, the coating materials of the invention, following their application, are cured thermally at relatively high temperatures. It is advantageous in this case to employ temperatures of from 80xc2x0 to 180xc2x0, preferably from 100 to 170, and in particular from 120 to 160xc2x0 C. The duration of curing may vary widely and depending on the coating material of the invention may be from one minute up to several hours. For the thermal curing it is possible to employ the customary and known equipment such as forced-air ovens or IR lamps.
The coating material of the invention is of outstanding suitability in particular for the production of multicoat coating systems of the invention by the process of the invention.
The process of the invention starts in step (I) from the application of a basecoat material to the substrate surface or to the primer. The resulting basecoat film is not cured but merely dried. In step (II) of the process, the clearcoat material is applied wet-on-wet, followed by curing of the resulting basecoat/clearcoat film in step (III) of the process. In accordance with the invention, the basecoat material and/or the clearcoat material comprise(s) a coating material of the invention. If the basecoat material or clearcoat material used is not a coating material of the invention, customary and known aqueous basecoat materials, or customary and known clearcoat materials, are used instead.
The result is continuous, substantially diffusion-impervious, hard, glossy, elastic, single-coat or multicoat coating systems of the invention, without defects such as popping marks, streaks or cloudiness (haze), which are notable, furthermore, for particularly high chemical resistance and weathering stability.

Femoral acetabular impingement can occur when a portion of a proximal femur rubs unfavorably against an acetabulum. One form of femoral acetabular impingement is called “cam impingement” where a portion of bone protrudes on a proximal femur generally at a location on the femur where the femoral head and neck meet. The protrusion, in some instances, can rub excessively against the acetabulum. Another kind of femoral acetabular impingement called “pincer impingement” can occur where a portion of bone protrudes on

 Femoral acetabular impingement can occur when a part of a proximal femur rubs unfavorably against an acetabulum. One phase of femoral acetabular impingement is called “ cam impingement ” where a parcel of bone protrudes on a proximal femur generally at a location on the femur where the femoral read/write head and neck meet. The protrusion, in some example, can rub excessively against the acetabulum.
