<p>The invention concerns films or plates of acrylic polymers, in particular polymethylmethacrylate, rendered no drop by coating with a monomeric composition, polymerized and reticulated by ultraviolet light, consisting of: a) from 50 to 70% by weight of acrylates or methacrylates of C1-C12 alkyls, C4-C12 cycloalkyl, polycycloalkyl or alkylidene having from 7 to 14 C atoms; b) from 10 to 30% of acrylate or methacrylate of C2-C6 hydroxyalkyl; c) from 10 to 30% by weight of acrylic or methacrylic acid or their salts; d) from 1 to 10% by weight of a reticulation agent consisting of a polyfunctional acrylic monomer; e) from 0,01 to 3% by weight of hydrophilic colloidal metal oxides; f) from 0 to 0,06% by weight of a U.V. polymerization initiator, being 100 the sum of the a)+b)+c)+d)+e)+f) amounts.</p> |
