Abstract:
A motor vehicle finished with a coating material, said coating material comprising:a resin binder; and a pigment having a color which depends upon viewing angle, the pigment comprising: (A) at least one oriented color-producing substance having a liquid-crystalline structure with a chiral phase and at least one cross-linkable structure, wherein the at least one color-producing substance is integrated in a three-dimensional matrix via its at least one cross-linkable structure and exhibits therein a particular color when viewed at a particular angle, and (B) at least one color-neutral substance having at least two cross-linkable double bonds, wherein the at least one color-neutral substance is further integrated in the three dimensional matrix via its at least two cross-linkable double bonds and increases the cross-link density of the three dimensional matrix without affecting the particular color exhibited by the at least one oriented color-producing substance, wherein said pigment is substantially the same color at room temperature and at 130Â° C.
