Abstract
The present invention relates to a laminate comprising a polymethyl methacrylate layer having adheringly coated on at least one surface thereof a layer of polyvinylidene fluoride having a maximum thickness one-tenth the thickness of the polymethyl methacrylate layer; the total thickness of the polyvinylidene fluoride being no greater than about 400 microns. The invention also comprises the method of making such laminates.
Claims3
A laminate comprising a polymethyl methacrylate layer having coated on at least one surface thereof a layer of a polyvinylidene fluoride having a maximum thickness one-tenth of the thickness of the polymethyl methacrylate with the thickness of the polyvinylidene fluoride coating being no greater than 400 microns and an intermediate layer having the same optical properties as polymethyl methacrylate comprising a polymethyl methacrylate layer.
