发明名称 METHOD FOR PRODUCTION OF AN OBJECT AND OBJECT PRODUCED BY SAID METHOD
摘要 The object ( 10, 10 ') comprises a first layer ( 1 ), for example with a back injection of a second layer ( 2 ), whereby the first layer is plastically deformable and comprises a front face ( 1 a) and a rear face ( 1 b). The back injection of the first layer ( 1 ) takes place in an injection mould. Before the back injection, the first layer ( 1 ) is partly provided with a coating ( 4 ') on the front face ( 1 a) thereof and said coating is hardened. The first layer ( 1 ) is then placed in an injection mould ( 6 ). The first layer ( 1 ) is then back injected in the injection mould ( 6 ), thus forming the second layer ( 2 ), such that the first layer ( 1 ) is pressed with the front face ( 1 a) thereof on an inner side ( 7 ) of the injection mould ( 6 ) and the hardened coating ( 4 ') on the first layer ( 1 ) is deformed and at least partly pressed into the first layer ( 1 ). The coating ( 4 ') is preferably applied by printing, for example by means of a screen printing method. The method permits the production of back-injected films with a front face ( 1 a) which is structured or at least appears to be.
