    • The invention relates to a process for the production of decorative coatings, comprising the following steps:

      A) providing a substrate to be coated and a backing film coated on one side with an uncured or only partially cured coating of a coating composition curable by means of high-energy radiation,
      B) forming zones on the backing film which are opaque to high-energy radiation and correspond to the negative image of a desired pattern or decoration,
      C) applying the coated side of the backing film having the uncured or only partially cured coating of a coating composition curable by means of high-energy radiation with the coated side thereof onto a substrate surface,
      D) curing the coating applied by the backing film by irradiation with high-energy radiation through the backing film,
      E) removing the backing film from the coating which remains on the substrate, and
      F) removing the un-irradiated and thus uncured parts of the coating remaining on the substrate to obtain the desired pattern or decoration.
    • 本发明涉及一种用于生产装饰涂料的方法,包括以下步骤:A)提供待涂布的基材和在一侧涂覆有未固化或仅部分固化的涂料组合物的背衬薄膜,涂料组合物可通过 高能量辐射,B)在背衬膜上形成对高能辐射不透明并对应于所需图案或装饰的负像的区域,C)将具有未固化或仅部分的背衬膜的涂覆面 通过高能量辐射可固化的涂层组合物的固化涂层,其涂覆侧在基材表面上,D)通过经由背衬膜的高能辐射照射来固化由背衬膜施加的涂层,E) 从保留在基底上的涂层得到背衬膜,以及F)去除残留在基底上的未被照射的和未固化的涂层部分以获得所需的图案 或装饰。

    • Designed to carry out a method of transferring the ornamental designs produced on a tubular bag or transfer pattern, within which the section to be decorated is accommodated, a vacuum being applied to the said bag during a phase of heat treatment within an oven, comprising an oven in which two laterally adjacent chambers (1-1') are provided, equipped with respective seatings (6) and (7) which enter the oven in its lower region and which project substantially therefrom, to an extent corresponding to the length of the sections, each seating being intended to receive a frame (8-9) from a pair of auxiliary tables (10) and (11) on which the loading and unloading of the said sections (16), with their corresponding bags (17), takes place, to which bags the vacuum is applied by coupling their ends to two guides (18) through which vacuum tubes (20) pass, on which vacuum tubes sealing sleeves (19) and opening/closing keys (21) are mounted, the vacuum tubes (20) initially being connected to vacuum pumps (12) and (13) situated on the tables (10) and (11), and subsequently being connected to vacuum pumps (14) and (15) situated on the seatings (6) and (7).
