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/o

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.

A wear-resistant glossy laminate comprising a backing and a thermoset resin impregnating facing sheet laminated thereto, said facing sheet having an upper facing surface having an ultra-thin wear resistant layer thereon which protects the glossy nature of said surface when exposed to the abrasive effects of sliding objects, said ultra-thin wear resistant layer comprising means for resisting surface dulling consisting of abrasion resistant particles having a hardness of 7-10 on the Moh scale and a maximum particle size up to 7 micrometers and in the substantial absence of abrasion resistant particles of 7 micrometers and a greater size, said particles being held in place on said upper facing surface by a small amount of binder material sufficient to hold said particles on the upper facing surface of said facing sheet.
