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当适用于各种塑料基材的塑料成型件涂覆方法、一种用于该涂覆方法的金属蒸发紫外线固化下涂层,以及一种通过该涂覆方法获得的塑料成型件。
涂覆塑料成型件的方法包括
将用于金属蒸发的紫外线固化涂层涂覆到塑料基材上、
然后将涂层基材置于紫外线照射下以形成底涂层膜、
在涂膜上蒸发金属,以及
在金属表面涂上透明涂层,形成透明涂膜层、
其中,用于金属蒸发的紫外线固化下涂层包括丙烯酸树脂,其成分包括至少一种单体(a),选自(甲基)丙烯酸二环戊酯、(甲基)丙烯酸二环戊烯酯和(甲基)丙烯酸异冰片酯、分子内至少有两个(甲基)丙烯酰基的化合物和光聚合引发剂。
