Definitions
- the invention relates to colored laser marking and laser inscription of plastics, which is based on welding a polymer-containing inscription medium to the plastic surface.
- marking method 1 for example, metals react to laser radiation with different tempering colors, woods become dark at the irradiated areas (charring) and plastics such as PVC show light or dark discolorations (foaming, carbonation) depending on the color of the plastic.
- a laser beam of suitable energy and wavelength e.g. IR laser
- IR laser e.g. IR laser
- the labeling medium is transferred to the material and fixed there.
- Amount of laser pigment is much less than e.g. B. with the master batch additive (labeling method 1).
- Labeling media made of glass frits or glass frit precursors with laser energy absorbers, which — depending on the desired color — are mixed with inorganic and organic pigments, organometallic substances or metal powders are generally known to the person skilled in the art. Such methods are such. B. described in WO 99/16625, US 6,238,847, and WO 99/25562.
- plastics can be labeled in color if a polymer-containing labeling medium is welded to the plastic surface under the action of laser light.
- the plastic to be labeled does not have to contain any substances that absorb laser light.
- the technical solution consists of separating the energy absorber from the actual color-providing labeling medium in a defined manner.
- the invention therefore relates to a method for permanent and abrasion-resistant colored labeling or marking of plastics, which is distinguished by the fact that a layer system is used which consists of two superimposed layers separated by a carrier film, the first layer consisting of a plastic, which contains an energy absorber intrinsically or as a layer and the second layer, which is applied to a carrier film, serves as the labeling medium and contains a colorant and a polymer component, the polymer component being welded to the plastic surface during the labeling / marking under the influence of laser light.
- Colored laser marking and labeling means the marking and labeling of a plastic using all bright and achromatic colors including black, white and all shades of gray.

Then films with a layer thickness of 5 - 200 ⁇ m manufactured. Depending on the layer thickness, the finished film contains 0.05 - 10% by weight of energy absorber.
- nitrocellulose is dissolved in the ethyl acetate solvent and stirred well.
- the polypropylene powder and the colorant copper phthalocyanine are then stirred in and a homogeneous paste is produced.
- the paste is applied with a 90 ⁇ m squeegee to polyester films with a film thickness of 5 - 250 ⁇ m and dried.
- Titanium oxide is used as the colorant.
- Example 7 Production of a polymer-containing labeling medium (3)
- the paste is applied with a layer thickness of 225 ⁇ m on polyester films with a film thickness of 5 - 250 ⁇ m and dried.
- Example 8 Production of a polymer-containing labeling medium (3)
- Titanium oxide Kronos 2220, 2222, 2063S, 2090, 2310, from Kronos International, Inc.
- Irgazin DPP Red from Ciba Geigy
- Sandoplast Blue from Clariant
- Example 10 Production of a multilayer labeling tape
- the carrier film - energy absorber layer (Examples 1-4) is with the
- Carrier film - labeling medium (Examples 5-9) folded together and laminated together using a hot laminator (model 647 from Erichson).
- the heated roller is set to a temperature of 140 - 175 ° C. After hot lamination, both foils are firmly connected.
- Example 11 Production of a multilayer labeling tape
- the labeling medium (examples 5-9) is drawn onto the carrier film — energy absorber film (examples 1-4) with a layer thickness of 225 ⁇ m and dried.
- Example 12 Production of a multilayer labeling tape
- a polymer-containing labeling medium with a layer thickness of 0.5-1, 5 ⁇ m and a laser absorber layer on the laser side are applied on the label side a layer thickness of 0.7-1.5 microns printed.
- Labeling medium (Fig. 1-4) are used for the permanent marking and labeling of plastics using the following types of lasers: a) Nd: YAG (cw operation)
- Nd YV0 4 laser (cw operation, pulsed) 16 watt laser from Rofin Sinar Nd-YVO 4 (1064 nm)
- Laser intensity 20-90%, cw operation, pulsed pulse frequency: 10 - 100 kHz
- Pulse frequency 20000 Hz
- Wobbier frequency 16 Hz pulse duration: 0.05 ms
- the colored lettering and markings in pulse mode are characterized by - higher edge sharpness. smoother surface at the marked points.
