Definitions

  • the invention relates to a method for bronzing color prints treated with negative pressure ink using non-flowable pearlescent pigments.
  • Such a pollution of the environment is also caused by heavy metals. This is particularly the case when cleaning and rinsing water exceed a limit of 2 mg / I Cu. This value can be exceeded by using bronzes containing heavy metals from labeled bottles.
  • labels on wine bottles have Cu contents of up to 16.5 mg / label. Such contents are stated by Trogus and Rasenberger in "Der Irish Weinbau", 3, 1983, page 112. These Cu contents reach cleaning and rinsing water from recycled bottles in sewage treatment plants and thus in municipal sewage sludge.
  • DE-A-3 224 558 describes the use of pearlescent pigments in printing technology.
  • the invention according to DE-A-3 224 558 relates to the use of titanium dioxide / mica pearlescent or colored gloss pigments known under the name "pearlescent pigments for cosmetics” as known commercial products as non-polluting, heavy metal pollutant-free, shiny metallic color pigments Printing technology especially for labels with gold or metal. Effect on glass bottles or packaging material of various types, or on objects such as book spines, leather, plastic material.
  • the invention goes beyond this prior art. It is the object of the invention to use pearlescent pigments of this type directly instead of the bronzes based on heavy metals, such as Cu, which have hitherto been used to achieve gloss effects.
  • the blockage should be removed by resilient metal strips (d) on the sloping longitudinal wall.
  • the design of this bronze container is different, as shown in Figure 1.
  • the front longitudinal wall is steep and the wall on which the sheet metal strips are located is formed obliquely.
  • the front wall of the bronze box is inclined and the longitudinal wall on the outlet side is vertical.
  • the flow angle according to this prior art is greater than 45 °. With a flow angle of 45 °, practically no storage volume of the specifically light bronze from pearlescent pigments can form.
  • GB-A-725 884 describes a bronze case for heavy metal bronzes with 2 sloping walls.
  • the "scoop-on-pick-up roller (d)" corresponds to the usual application roller.
  • This "application roller” is provided with a plush-like coating in order to improve the adhesion of the heavy bronze.
  • This device has numerous, independently movable plates which are intended to regulate the outlet of the bronze particles which are free-flowing.
  • the flow angle is also greater than 45 °.
  • Calcined rutile pigments are proposed as the base pigments.
  • the Ti0 2 layer is small; this should amount to 50-500 mg Ti0 2 on mica flakes with a diameter of 5-200 microns and a thickness of 0.1-5 microns.
  • a thin layer of a poorly soluble Cr-III compound is applied to the coated mica pigment and converted into Cr 2 0 3 by annealing.
  • These pigments have a much lower heavy metal content, which in the very thin top layer is already below the permissible limit.
  • this includes the abolition of the agglomerate structure of the pearlescent pigment.
  • This solution is characterized in that the pearlescent pigment is converted into the flowable state by extending the length of the application roller (1) the bronze box (2) above it, which is set down so deep that, seen in cross-section, with its vertical wall surface (4) and with its wall surface (5) inclined to the applicator roller, as a lower limit at the height of the horizontal diameter (6 ) is arranged through the axis of the application roller (1), on the rotating surface of the application roller (1) emerges from the volume of the bronze wedge formed with the specifically light pearlescent pigment bronze, controlled by adjustable sliders (3, 3a, ... 3n ) and carried over the surface of the application roller (1) to the opening gap (13) of the opening slide (3, 3a ...
  • the bronze wedge (7) seen in cross section, from the upper arc section (8) between the Inclined surface and the upper line on the application roller (1), from the inclined surface (5) and by the upper line (9) on the application roller (1) is formed by the flow angle (10) of 45 °, which, seen in cross section , a us of the vertical wall surface (4) and the line (11) to the upper point (12) of the application roller (1) in the outer, horizontal point (13) on the application roller (1) is formed, flows continuously and uniformly in such a specific amount that the printed sheets are given the previously determined opacity, then the non-adhesive amount of the pearlescent pigment is removed by brushing off the bronzed printed sheets, the bronzed printed sheets are carried out and stacked and the brushed pearlescent pigment is introduced into a collecting container.
  • the configuration of the method of the invention results from the preferred measures of the subclaim.
  • the technical effect of creating the flowability from the non-flowable state of the pearlescent pigments from the bronze box is based on the elimination of the agglomerate structure of the individual particle particles.
  • a sample is taken by immersing it in the bronzing compound, which practically covers the curved surface as a heap.
  • the non-flowable state is defined by the fact that the bronzing compound does not run off the horizontally held round surface.
  • Such copper bronzes have, for example, a copper content of 60 to 85% by weight. It can be seen that brushed copper bronze flows slowly and incompletely. This has changed not only in its original gloss effect in the direction of a matt, irregular gloss effect and in the color strength, but also in its structure, in particular due to agglomeration of the primary particles.
  • the process of the invention means the technical measure of "bronzing" not only the application of bronzes according to the prior art, but also figuratively the application of the pearlescent pigments without Cu content and with only a low Cr content.
  • Figures 1 and 2 explain the operation according to the method of the invention.
  • Figure 1 shows the design of the bronze box (2) over the applicator roller (1) in cross section.
  • Figure 2 shows the longitudinal view of the arrangement of the bronze box also in a schematic arrangement.
  • a throughput of 1.3 to 1.5 kg of a Cu-free pearlescent pigment as bronze from the bronzing box (2) to the application roller (1) For example, with a length of the application roller of 1.32 mm, with a diameter of the application roller (1) of 70 mm and with the length of the vertical wall surface (4) of 130 mm and the inclined wall surface (5) of 160 mm an upper width of the bronzing box (2) of 110 mm, a throughput of 1.3 to 1.5 kg of a Cu-free pearlescent pigment as bronze from the bronzing box (2) to the application roller (1).
  • the continuously and uniformly flowing pearlescent pigments are metered in precisely at the required points across the width of the printing sheet passing through the bronzing machine.
