Abstract: A polymerizable mixture containing acrylic acid or a partially cross-linked oligomer acrylate is used for the manufacture of a non fogging or low fogging layer on a substrate. The polymerizable mixture contains 1 to 10% W of a salt, in particular a salt of acrylic acid, as well as any necessary further additives.
Abstract: A three-dimensionally crosslinkable resin is applied to a sheet of thermoplastic material, and cured to form a scratch resistant coating on the sheet. The coated sheet is then subjected to the action of heat and uniform area pressure between polished surfaces. This pressing treatment results in an optically smooth surface of the coating.
