Abstract: Multilayer transparent, antireflex, coloured or opaline plates, with smooth or embossed surfaces, optionally thermouldable with external layers in acrylic polymers, low thickness, in the range of 1.5 up to lower thicknesses of 10 mm, by employing one or more polymeric continuous films which have the property to have elastic modulus lower than the one of PMMA of at least 30%, and/or elongation at break higher than at least 40%, measured by the test according to ISO 527 for plates or films, placed inside the panel.

Abstract: Antinoise and antifragmentation plates based on acrylic polymers employing a polymeric continuous film placed inside the plate, wherein the film is characterized by an elastic modulus lower than the one of PMMA of at least 30%, and/or elongtion at break higher than at least 40%, measured by the test according to ISO 527 standard for plates or for films.

Abstract: The invention refers to a process to render antiscratch and antiabrasion shaped articles based on thermoplastic acrylic polymers consisting in coating the article by a composition comprising(A) 55-95% by weight of at least a (meth)acrylic monomer and/or oligomer having at least two double bonds;(B) 5-25% by weight of monomers and/or oligomers of divinylethers and/or epoxides(C) 0-20% by weight of monomers and/or oligomers containing polar groups of monofunctional (meth)acrylaytes and/or monovinylethers, when (A) or (B) do not contain polar groups, and comprising a mixed system of photoinitiators of radical and cationic type, then in submitting the coated article to U.V. irradiation, at temperatures of 30.degree.-70.degree. C. to polymerize and crosslink the coating in situ.
