Abstract
A plate comprising two layers of different colours is produced by pouring methyl methacrylate or a syrup-like mixture of methyl methacrylate monomer and polymer, having a desired colour, into a mould having the bottom consisting of a plate of polymethyl methacrylate having a different colour, and effecting polymerization of the poured material on the underlying plate in an oven provided with an air circulation adjusted to a constant temperature of about 50 DEG C. for 10 to 24 hours.ALSO:A plate comprising two layers of different colours is produced by pouring methyl methacrylate, or a syrup-like mixture of methyl methacrylate monomer and polymer, having a desired colour, into a mould having the bottom consisting of a plate of polymethyl methacrylate having a different colour, and effecting polymerization of the poured material on the underlying plate in an oven provided with an air circulation adjusted to a constant temperature of about 50 DEG C. for 10 to 24 hours.
