Definitions
- the present invention relates to metallic substrates having visually contrasting surfaces which are suitable e.g. for the production of containers such as beverage cans and the like or are such containers .
- This object is achieved by coating the metallic substrate with only one single coloured layer and partially, i.e. in the desired areas, removing (evaporating) this layer incompletely by laser irradiation.
- removing (evaporating) this layer incompletely by laser irradiation.
- a thin transparent "skin" or film remains which is substantially thinner than the lacquer layer. Since this skin is surprisingly translucent, the colour of the metallic substrate becomes visible, so that visual contrasts appear.
- Pig. 1 schematically illustrates the process according to the invention and the resulting product:
- a metallic substrate 1 is fully coated with a coloured layer 2 prior to laser ablation (A) .
- a remaining transparent layer 3 which is substantially thinner than the original coloured layer is shown in B in the areas 4 where the laser beam stroke.
- fig. 2 illustrates the known process mentioned in the introductory part, in which, under the (first) coloured layer 2 ' , the metallic substrate 1' comprises a second, differently coloured layer 5' which is directly applied onto the substrate (A'). It follows from B' that the striking of the laser beam results in the full evaporation of the first coloured layer in the affected areas 4' whereas the majority of the second layer 5' is maintained, so that the colour of the second layer 5 ' becomes visible for a viewer in the areas 4 ' .
- the thickness of the coloured layer can be chosen freely and is determined by common considerations (scratch resistance, price, etc.). While in prior known processes the thickness of the lower coloured layer was usually 3 - 4 ⁇ m and the layer on top thereof was thinner ⁇ e.g. about 0.5 to 2 ⁇ m) , the thickness of the only and coloured layer of the invention may for example be the same or less (e.g. about 2 to 4 ⁇ m, preferable less than 3 ⁇ m) compared to what was usual in known processes. Due to the laser ablation, a considerably thinner layer (e.g. having a thickness of only 1/6 to 1/3) remains, e.g.
- laser ablation may be carried out according to conventional methods.
- the laser ablation is effected by applying a mask or stencil which covers, or vice versa exposes, letters, words, logos, figures or the like or by a printing method, e.g. printing in a dot-matrix form.
- the energy to be actually generated can easily be calculated by a person skilled in the art and depends on the layer thickness. Of course, higher energy will lead to greater ablation.
- the energy to be generated is markedly lower than the one used in the prior art when the layers have equal thickness. Therefore, it suffices to use an NO laser for carrying out the process according to the invention.
- the adjustment is made such that the greater part (see above) of the coloured layer is removed from the exposed areas and the remaining skin becomes transparent in these areas, so that the metallic substrate appears as the second colour so that it appears as if it were a two-colour print.
- the single coloured layer may be a common lacquer, e • . g . an epoxy resin-type lacquer.
- a common lacquer e • . g . an epoxy resin-type lacquer.
- dark colours being especially suitable due to the better contrast with the metallic translucent substrate (e.g. aluminum, steel) .
- the remaining thinner and colourless layer acts as a protective layer protecting the metal from atmospheric influences and/or as a contact barrier vis-a-vis any other substances which could attack the metal, and thus also as a protection against corrosion.
- New coated metal sheets can be produced in a simple way by means of the process according to the invention. These sheets are anti -corrosive as well as have an attractive graphic form.
- the process is also suited for the production of metal containers such as cans which are either "painted” according to the invention after shaping or produced from metal sheets treated according to the invention.
- specific areas of the containers or cans may be treated according to the invention, e.g. the bottom and/or the tab.
- the back side of the tab may be provided with a very small mark which serves for the manufacturer or insiders as an identification or the like.
