ABSTRACT The invention concerns films or plates of acrylic polymers, in particular polymethylmethacrylate, rendered no drop by coating with a monomeric composition, polymerized and reti- culated by ultraviolet light, consisting of: a) from 50 to 70% by weight of acrylic or methacrylic est- ers of C2-C18 aliphatic glycols or of (poly)alkylenoxides formed by 1 to 6 units of of C2-C4 alkyleneoxide; b) from 10 to 30% by weight of C2-C6 hydroxyalkyl acrylate or methacrylate; c) from 10 to 30% by weight of acrylic or methacrylic acid or their derivatives; d) from 1 to 10% by weight of a reticulation agent consi- sting of a polyfunctional acrylic monomer containing at least three double bonds, the components of class a) excluded; e) from 0.01 to 3 parts by weight for 100 parts by weight of a+b+c+d of hydrophilic colloidal metal oxides; f) from 0 to 0.06% parts for 100 parts by weight of a+b+c+d of a U.V. polymerization initiator, being 100 the sum of the a+b+c+d amounts. Description of the industrial invention in the name: ATOHAAS C.v., of Dutch nationality, with head office in Shipholpoort 60, 2034 MB Haarlem, Holland.
