Definitions
- the present invention relates to an at least partially radiation-curable coating film based on urethane acrylates for coating substrates.
- DE-PS 2346424 describes the preparation of radiation-curable compositions, starting from acrylic esters of polyhydric alcohols and secondary, aliphatic monofunctional amines. These masses have the disadvantage of reduced storage stability. The addition of a secondary amine also leads to a reduction in the acrylic ester functionality of the molecule and thus also to a reduction in the crosslinking possibilities for the radiation-induced polymerization.
- a transferable lacquer film is known in which, in particular, acrylic resin lacquers are applied to a carrier film, from which these can then be transferred to the background to be lacquered, a wax-like separating layer being intended to facilitate detachment from the carrier film while a self-adhesive glue is used to stick the lacquer on (col. 4, lines 31 ff.).
- German utility model G 81 30 861 is a multi-layer
- Known label which consists of a thin and a thick layer of lacquer, both electron-beam hardened and applied solvent-free, the two layers of paint have a good color contrast.
- the upper lacquer layer can be burnt by laser so that the lower lacquer layer is visible in a contrasting color to the upper, as lettering or the like.
- Such a label can be stuck on using a pressure sensitive adhesive, hot glue or reactive adhesive (p. 2, line 18), with pressure sensitive adhesives being preferred.
- pressure sensitive adhesives being preferred.
- such products are less suitable for painting surfaces.
- EP 230.364 B1 discloses composite materials for transferring paints, in which an at least partially heat-activatable adhesive is used, with a specific glass transition point and modulus of elasticity.
- the disadvantage of these products is that they are not radiation-curable.
- EP 283.651 B1 also describes lacquer layers and lacquer films in which the lacquer is applied in several layers to a radiation-permeable plastic film and cured by irradiation through this film.
- lacquer films can be provided with an adhesive layer (p. 4, line 22/23) which contains free chemically reactive groups and synthetic resin or plastic, in particular with a mixture of polyisocyanate and hexamethylenetetramine and an OH group-containing PVC Copolymer (p. 5, lines 16-24).
- Solid colors require a two-layer structure, top layers are created with solvent-based paints, - print layers also,
- a preferred direction of structuring is unavoidable by roller application processes, Not all degrees of matting can be achieved, since the structure is created via the top layer and is leveled by applying the print and transparent layers.
- the transparent layer is particularly protected against external contamination by the process, ie clean room conditions are required.
- EP 547.506 AI describes a process for aluminum coating, a multilayer composite being built up on a carrier film. Finally, an adhesive layer is applied (column 4, lines 45-53), based on epoxy, polyester, polyurethane, acrylate, Urea or the like, with sufficient crosslinking agent also being used.
