    摘要： The invention relates to a method for coating plastic substrates, a transparent coating agent comprising at least one radiation-curable binder (A), nanoparticles (B), reactive diluent (C), and optionally solvent being applied to the plastic substrate, characterized in that the coating agent contains (i) 30 to 60 wt %, relative to the total weight of the components (A1), (A2), (A3), (B), (C1), (C2), and (C3), of the nanoparticles (B), (ii) 15 to 40 wt % of one or more urethane (meth)acrylates (A1) having on average 3 to 5 acrylate and/or methacrylate groups per molecule, (iii) 0 to less than 10 wt % of one or more urethane (meth)acrylates (A2) having on average more than 5 acrylate and/or methacrylate groups per molecule, (iv) 0 to less than 10 wt % of one or more urethane (meth)acrylates (A3) having on average less than 3 acrylate and/or methacrylate groups per molecule, (v) 55 to 80 wt % of one or more monomeric and/or oligomeric compounds (C1) differing from the components (A1), (A2), and (A3) and having 4 acrylate and/or methacrylate groups per molecule, (vi) 0 to 15 wt % of one or more monomeric and/or oligomeric compounds (C2) differing from the components (A1), (A2), and (A3) and having 2 acrylate and/or methacrylate groups per molecule, and (vii) 0 to 15 wt % of one or more monomeric and/or oligomeric compounds (C3) differing from the components (A1), (A2), and (A3) and having 3 acrylate and/or methacrylate groups per molecule, wherein the sum of the weight fractions of the film-forming components (A1), (A2), (A3), (C1), (C2), and (C3) is 100 wt %. The invention further relates to the coated polycarbonate substrates obtainable by the method and to the use thereof.

    摘要： The present invention relates to a process for the coating of polycarbonate substrates, in particular of transparent polycarbonate substrates, by applying a transparent coating composition encompassing at least one radiation-curing binder resin (A) and/or reactive diluent (C), nanoparticles (B), optionally solvent and at least one light stabilizer (L), to a polycarbonate substrate, wherein the coating composition comprises at least one light stabilizer (L) which comprises, per molecule, an average of at least one ethylenically unsaturated group bonded by way of a urethane group. The present invention also relates to the coating compositions used in said process, and to the coated polycarbonate substrates obtainable via is the process, and to their use.

    摘要： The invention relates to a thermally hardening, transparent coating substance containing, each time with regard to A), (B), (C) and (D): (A) 10 to 40 % by weight of a (meth)acrylate (co)polymer having a numerical mean molecular weight ranging from 1,000 to 6,000 Dalton, a glass transition temperature ranging from -15 to +70 °C and a hydroxyl number ranging from 80 to 200 mg KOH/g; (B) 10 to 40 % by weight of a polyester having a numerical mean molecular weight ranging from 800 to 6,000 Dalton, a hydroxyl number ranging from 80 to 200 mg KOH/g and an acid number ranging from 1 to 50 mg KOH/g containing, with regard to the polyester, 30 to 70 % by weight of cycloaliphatic structural units; (C) 10 to 40 % by weight of a blocked polyisocyanate, wherein the blocked polyisocyanate groups are bound to flexible- rendering structural units that, as a constituent of a three-dimensional network, lowers the glass transition temperature thereof, and; (D) 10 to 40 % by weight of a blocked polyisocyanate, wherein the blocked polyisocyanate groups are bound to hard-rendering structural units that, as a constituent of a three-dimension network, increases the glass temperature thereof. The invention also relates to a method for producing the inventive coating substance and to the use of this substance.
