<p>A low gloss interior automotive laminate has a finish with a tactile property that imparts a soft low friction quality to the finished part surface. The laminate comprises a base coat/clear coat decorative transfer film bonded to a polymeric substrate. The outer clear coat, which provides the functional characteristics of the surface finish, is formed by casting it on a low gloss release coated carrier. The clear coat preferably comprises a water-borne aliphatic urethane dispersion having a low cross-linking density and containing a dispersed flatting agent. The crosslinked polymer provides soft low surface friction properties with improved hardness and tensile strength while maintaining thermoformability. The color coat which comprises a solid color or print pattern is coated on the dry clear coat or on an intervening tie coat for adhesion. The base coat/clear coat film is removed from the carrier and laminated either to a thermoformable polymeric sheet, to a thin polymeric substrate sheet, or to an extruded substrate sheet. The transferred film is shaped by thermoforming or molding it to a three-dimensional configuration under which the outer surface is elongated while maintaining the desired soft tactile finish in combination with a low gloss outer surface having a 60° gloss from about 1 to about 5 gloss units.</p> |
