    • It is an object of the present invention to provide a method of coating a plastic molding which is appropriately applicable to various plastic substrates, an ultraviolet-curable under coating for metal evaporation, which is to be used in that method of coating, and a plastic molding obtained by that method of coating.A method of coating a plastic molding comprising steps of applying an ultraviolet-curable under coating for metal evaporation to a plastic substrate, then subjecting the coated substrate to ultraviolet irradiation to form an under coating film, evaporating a metal on the coating film and applying a clear coating to the metal surface to form a clear coating film layer, wherein the ultraviolet-curable under coating for metal evaporation comprises an acrylic resin comprising, as a constituent, at least one monomer (a) selected from among dicyclopentanyl (meth)acrylate, dicyclopentenyl (meth)acrylate and isobornyl (meth)acrylate, a compound having at least two (meth)acryloyl groups within the molecule, and a photopolymerization initiator.
    • 本发明的目的是提供一种适用于各种塑料基材的塑料模制品的涂覆方法,用于该涂覆方法的金属蒸发的紫外线固化的下涂层,以及塑料 通过该涂布方法获得的成型。 一种涂塑料成形体的方法,其特征在于,包括以下步骤:向塑料基材施加紫外线固化型底涂层以进行金属蒸镀,然后对涂布的基材进行紫外线照射,形成底涂膜,蒸镀涂膜上的金属, 透明地涂覆到金属表面以形成透明的涂膜层,其中用于金属蒸发的可紫外线固化的底涂层包括丙烯酸树脂,其包含作为组分的至少一种选自以下的单体(a):(A)选自二环戊基(甲基)丙烯酸酯, (甲基)丙烯酸二环戊烯酯和(甲基)丙烯酸异冰片酯,分子内具有至少两个(甲基)丙烯酰基的化合物和光聚合引发剂。
