Definitions

  • the invention relates to a coating film for a plastic part and a plastic part coated with such a film.
  • the invention applies in particular to the field of plastic parts for the automotive industry, and in particular for aesthetic pieces with a function decorative.
  • An object of the invention is to provide a coating film producing an effect original aesthetic, while being simple and economical to produce.
  • the subject of the present invention is a coating film for a workpiece plastic, comprising a transparent protective layer and a decorative layer, the decorative layer resulting from the superposition of at least a first and a second patterns printed successively on the protective layer, characterized in that the first pattern printed on the protective layer consists of a non-tint covering.
  • not covering means that the shade has an opacity insufficient to mask the ink layer (s) over which the pattern is printed.
  • the underlying patterns are visible, but only if the lighting conditions and angle of view allow this. This is notably the angle of light reflection on the film which conditions the visibility of the underlying patterns.
  • all the patterns successively printed on the protective layer consist of non-covering shades.
  • the overlapping of the shades at the locations of the coinciding patterns with two different patterns locally increases the opacity of the resulting shade and provides another variant of visual effect, which also appears more or less clearly according to lighting and viewing conditions.
  • the film has a base layer constituted by a covering shade, possibly metallized. This layer allows increase the contrast between the light and shadow areas and thus vary the contrast between the base layer and the patterns.
  • At least one of the colors is metallic, and preferably all because of the better visual rendering obtained.
  • the invention proposes, according to another mode of realization, to use shades that form a monochrome with another shade, for example with the background tint.
  • the invention also relates to a plastic part coated with a film. as described above.
  • FIG 1 there is shown schematically two patterns 1, 2 superimposed on a metallic background 3.
  • Each pattern consists of a set of all identical spots, pseudo-oval.
  • the spots are oriented identically and are distributed to nodes of a regular square mesh network.
  • the longitudinal direction of the spots in pattern 1 is different from the direction longitudinal of the spots in motif n ° 2.
  • the combination of the two patterns is shown in Figure 1.
  • the spots of the two patterns hide the background metallized, the brightness of which from the reflection of light creates a variation of contrast between the background and the patterns.
  • the light contrast between the shadow areas and light areas is more important for the background than for the patterns.
  • FIG. 3 not only the metallic background 3 and the two patterns are shown. 1, 2 previously described, but also a substrate 4 and a protective layer transparent 5 which protects the film.
  • this transparent protective layer is a layer of transparent plastic material on which the two are successively printed patterns, then the bottom.
  • the printed transparent layer and the substrate are then combined by any appropriate means.
  • FIG. 4 shows different zones of luminosity of the metallized background 3.
  • variable brightness can be divided into three zones, namely zone 8, in which the reflection is direct, a zone 9 contiguous to zone 8 in which the reflection is indirect and a zone 10, distant from zone 8, in which the reflection is almost nil.
  • FIG. 5 represents the result of the combination of the patterns and the brightness of the background, in each of zones 8, 9 and 10, of two identical patterns 11, 12 in network with square mesh, the spots of which do not have the same orientation with respect to the other.
  • Zone 8 of direct reflection provides maximum illumination.
  • the contrast is very marked between the metallic background and the pattern stains which, although not opaque, appear opaque, so the aesthetic effect rendered is similar to that in Figure 2, the spots appearing opaque.
  • zone 9 of indirect reflection which benefits from less lighting, only the regions in which the spots are superimposed appear to be opaque, the others being of a level of luminosity close to the metallic background and merging with him.
  • the resulting pattern has a significantly different overall visual appearance than that of the zone 8.
  • zone 10 the luminosity of the metallized base layer is low. Tasks mask the base layer, except where they are superimposed and where their reflective character is similar to that of the base layer. This results in a drawing which is complementary to the drawing obtained in zone 9.
  • FIG. 6 provides an overall visual effect which is best visible in Figure 6, in which a first region, located on the left in the figure, represents only the first motif 11, a second region, located on the right in the figure, represents only the second motif and the central region corresponds to the combination of the two motifs, seen in zone 9.
  • the color of the base coat can be provided by the substrate, without printing extra over the patterns printed on the protective layer. This possibility also exists for patterns of identical shades.
  • the 8 'zone with a high luminosity of the background layer, gives an effect similar to that of zone 8 of figure 5.
  • the zone 9 ′ reveals only the first pattern 11, while the zone 10 'reveals the second pattern 12 in the regions where it is not superimposed at the first ground 11.
