ABSTRACT:
A ski having an outer appearance layer constituted by a sheet of thermodeformable material which is heat deformable during a molding process. The sheet of thermodeformable material forming the appearance layer is composed of at least one outer layer of a substantially transparent plastic material and an inner layer made from substantially opaque plastic material. The inner layer contains coloring agents defining a decoration or inscription which is visible from the exterior through the outer layer. The plastic materials forming the sheet of thermodeformable material are such that the melting point and the heat softening temperature of the material forming the outer layer is less than the melting point and the softening temperature of the material forming the outer layer is less than the melting point and the softening temperature of the material forming the inner layer. The molding process is also disclosed for producing such a ski. In the present invention, the inner decoration layer is not substantially deformed during the molding process.
