1. The sheet material with light reflective prisms soderzhaschiymnozhestvo discrete clusters of cube corner elements made of transparent material, which are separated from each other on all sides of the surface, each cube corner element has a main edge not collinear, or parallel to, the main ribs cubic cube corner elements on either side of it, wherein the cube corner elements in each cluster of a plurality of direct V-shaped grooves, each of which has substantially the same direction throughout its length, the cube corner elements have different orientations in such a way that the ability to retro-reflective sheet material is substantially insensitive to povorachivaniyu.2. With retroreflective sheeting of claim prisms. 1, wherein the surface separating clusters of discrete cube corner elements formed textured so as to provide the ability to dissipate svet.3. With retroreflective sheeting of claim prisms. 1 in which four or more of the cube corner elements in each cluster have edges which converge at a central point within klastera.4. The sheet material with reflective prisms of claim. 1, wherein the cube corner elements of the clusters contain the symmetrical pairs of cube corner elements.5. With retroreflective sheeting of claim prisms. 4 kotoromkubicheskie corner elements in each cluster comprising at least two symmetrical pairs of cube corner elements, and in which one of Cro
