Abstract
A glossy laminate is made using highly polished caul plates, the laminate having superior sliding can wear resistance, and without damaging the plates. This result is effected by use of the technology of Scher et al. U.S. Pat. No. 4,255,480; O'Dell et al. U.S. Pat. No. 4,491,137 and 4,567,087; and/or Ungar et al. U.S. Pat. No. 4,713,138, except that the particles size of the grit is maintained at less than 9 micrometers. In this way a glossy laminate is obtained which retains its glossy appearance under normal wear conditions, and without rapid destruction of the expensive polished caul plates.
