Definitions
- the invention relates to interference pigments based on liquid-crystalline polymers according to claim 1, an effect varnish according to the preamble of claim 18 and utility articles coated therewith, in particular motor vehicle bodies, according to the preamble of claim 27.
- the invention also includes a method for producing the interference pigments 10.
- Liquid-crystalline polymers are known, for example, from DE 40 08 076 A, EP 66 137 A and US Pat. No. 5,188,760.
- color pigments are usually stored in a clear carrier made of synthetic resin, which determine the desired color tone of the paint.
- the color effect of these pigments is based on a spectrally selective absorption effect, so that from the incident - white - light a spectrally broad part is absorbed by the pigments and only a spectrally narrow part is reflected.
- effect paints have been developed in an effort to achieve more brilliant color impressions, particularly in vehicle bodies.
- the metallic lacquers, small metallic flakes, inter alia are mixed into the carrier as pigments.
- coated mica particles are used as pigments.
- EP 383 376 AI describes such an effect lacquer in which small mica flakes are uniformly coated on all sides with a crosslinked, liquid crystalline polymer (LCP) are coated in a chiral-nematic arrangement. The color appearance of such pigments is caused by an interference phenomenon.
- Such platelet-shaped interference pigments which are aligned parallel to the painted surface, have a certain first color — basic color — when viewed orthogonally, and a second, shorter-wave color under an inclined viewing direction. This color appearance of the painted surface, which is dependent on the viewing angle, makes the coating very effective and very desirable for certain applications in which such color effects are positively received by the customer.
- a disadvantage is the complex production of the interference pigments, as a result of which the effect varnish and, accordingly, the effect varnish on the commodity are quite expensive.
- interference pigments based on polysiloxanes, each of which as a whole consists of small fragments of a thin, crosslinked film of liquid-crystalline polymers.
- These interference pigments themselves are colorless and clearly transparent.
- the color effect which can be achieved with them is based on the regular structure and the uniform arrangement of the molecules in the liquid crystal and on an interference due to a certain spectral light component for which the pigment has a reflective effect.
- the other light components pass through the pigment.
- astonishing color effects of different types can be achieved, depending on the design of the coating or the interference pigments and their mixture.
- this paint also offers a number of technical advantages.
- reference pigments have a specific weight of approximately the same size as the pigment carrier or the lacquer base.
- the entire color spectrum can be produced by mixing a few types of interference pigments in different ratios at the paint shop, the on-site storage can be limited to a few basic types of paint, so that the logic with regard to the different paint colors is considerably simplified.
- the interference pigments of the type mentioned are obtained by applying the liquid-crystalline polymers from the liquid state onto a smooth base, for example onto a polished roller, as a result of which a thin film is formed.
- the doctoring process results in alignment of the molecules within the film, the thinner the film, the better the alignment, and only after this alignment does the film have an interference color. Due to the monomer architecture of the molecules of the liquid-crystalline polymers, the shear process during the process of the doctor blade automatically equidistant network planes and thus color-selective diffraction structures.
- the effective interference color of the transparent and colorless pigments per se can be formed by adapting the equidistantly spaced network planes in terms of their network plane spacing to the wavelength of a specific color tone of the color-determining lacquer layer in the smectic or cholesteric phases of the interference pigments, which is achieved by suitable chemical structure-forming measures with regard to the molecular architecture can be achieved.
- the applicant was able to produce interference pigments with the basic color red and others with the basic color green.
- Intermediate colors can advantageously be produced by using different interference pigments are mixed together in a basecoat, the color position depending on the mixing ratio of the different interference pigments. Since the mixing ratios can be varied continuously, all color shades for the basic color tone can also be specified continuously.
- the color base tone of the interference pigments is determined by the color impression or the color which arises when the painted surface is illuminated vertically and viewed vertically. After the lattice plane spacings appear to be changed with respect to the orthogonal beam direction when the beam path is directed obliquely to the surface, the color impression shifts in the direction of a different color which is offset in the color spectrum towards shorter wavelengths, and this depends on the relative color Viewing direction of the surface. That Depending on the position of a certain surface area in relation to the viewer's beam path, the surface area appears in the basic color or in the other shorter-wave color. For example, interference pigments of the basic color red can change to the color green; with other interference pigments, a color change between green and blue can be represented.
- the intensity of the perceptible colors is stronger, the darker the color of the background which bears the color-determining lacquer layer, although the color of the background must be determined by absorptive color pigments. This is due to the fact that the light components passing through the interference pigments are more or less completely absorbed by the dark background, and the more so the darker the background.
- the lighter the background the greater the proportion of light from the non-interfering light is also reflected back from the background and overlaid with the proportion of light reflected by the interference pigments, so that the color intensity appears paler. So the lighter the background, the lower the color intensities of the base color and the color that is turned over Colour. This goes so far that no color effect can be achieved on, for example, chrome-plated blank parts, because there is no spectral intensity shift in the light on a reflective surface.
- a condition for the appearance of liquid crystalline phases is a rigid mesogenic molecular shape.
- the repeating units of liquid-crystalline polymers contain the mesogenic units.
- the two most frequently implemented molecular structures are the side chain LC polymers, in which the mesogenic units are chemically fixed as side chains of the polymer backbone, and the main chain LC polymers, in which the mesogenic units form the polymer backbone or part of the polymer backbone.
- a large number of copolymers can be prepared, which can contain different mesogenic units or non-mesogenic and mesogenic units.
- the object of the invention is to find a material base which is independent of the base of the polysiloxanes and which has an even better brilliance in the case of effect paints or effect paints, with regard to the various categories on which this category is based, namely interference pigments, processes for their production, lacquer or lacquered commodity can be expected in the color impression, the interference pigments used should have an even better chemical and physical compatibility with the conventional lacquer bodies and should also be technically simple and inexpensive to produce.
- the polymer networks obtained in this way no longer show liquid-crystalline transitions and they remain in a highly ordered state which is preserved until thermal decomposition.
- the colored films or the interference pigments are obtained by admixing a low-molecular chiral compound to the nematic component, which induces the formation of the chiral nematic reflecting phase.
- chiral compounds which have good liquid-crystalline and good crosslinking properties are preferably used in the production of the coloring films or pigments. If a cholesteric network with non-mesogenic diacrylates is produced, a crosslinker, e.g. a 1,4-diacryloyloxy benzene was added.
- a crosslinker e.g. a 1,4-diacryloyloxy benzene was added.
- nematic and chiral components used are available as commercial products or their production is known from the literature.
- the preparation of the nematic component di- [4- (6-acryloyloxyhexyloxy) benzoic acid] 1,4-phenyl diester is described by DJ Broer; J. Boven; GN mol; G. Challa; Macromol. Chem. 190. 2255 (1989) and the preparation of the nematic component 4- (8-acryloyloxy-3,6-dioxy-octoyloxy) 4'-methoxybiphenyl benzoate was carried out according to M. Engel; B. Hisgen; R. Keller; W. Kreuder; B. horizontal bar; H. Ringsdorf; H.-W.
- cholesteryl 4- (6-acryloyloxyhexyloxy) benzoate was prepared by esterification with cholesterol via the corresponding acid chloride.
- the 1,4-diacryloyloxy-benzene used as crosslinker was developed according to L. Liebert; L. Strzelecki; D. Vagogne; Bull. Soc. Chim. Fr. 9-10, 2073 (1975).
- the film produced in connection with the production of the interference pigments should have a thickness of 3 to 15 ⁇ m at least after curing. In the case of thinner films, the desired interference-causing color appearance is lost and in the case of thicker films the alignment of the molecules is not so good that the color appearance is impaired by a milky appearance.
- the interference pigments required in the present case are produced in platelet form, in which the side group mesogens are also or as before arranged at least approximately nematically and / or smectically and / or preferably cholesterically.
- the platelet-shaped interference pigments which can be used have a platelet diameter of the order of 5 to 100 ⁇ m or approximately one to ten times the film thickness; Smaller or larger particles, which arise when the hardened film is comminuted, have to be sorted out, for example, by sieving processes.
- the platelet-shaped pigments are automatically arranged in the basecoat parallel to the surface by shear forces.
- the small particles which are closer to the cube shape, do not align themselves parallel to the component surface in the applied lacquer, which is why they should be sorted out.
- the very large pigment platelets can cause problems when applying the lacquer, which is why such large pigments should also be sieved out .
- the background of the color-determining lacquer layer is kept in a color which is caused by absorption pigments and which roughly corresponds to the basic color or to the color of the interference pigments which has been turned over. This ensures that the color that matches the background appears particularly intense and brilliant.
- the color of the lacquered surface also appears in the relevant color tone of the substrate, but is tinted in the other color of the interference pigments and covered with finely divided glitter dots.
- absorption pigments to the effect lacquer, which may contain different interference pigments.
- dark absorption pigments to the effect varnish according to the invention, an entirely comparable impression can be achieved as through a dark background. The situation is similar when admixing light absorption pigments; they weaken the color change and the individual color intensities.
- absorption pigments in one of the effect colors By mixing absorption pigments in one of the effect colors, an intensification of this color impression can be achieved at the expense of the color effect of the other effect color.
- absorption pigments to the effect varnish if a - for whatever reason - a lighter or even a shiny metallic background with effect paint should be painted. Such a task can arise, for example, when repainting end-of-life vehicles or when repairing paintwork.
- the polymer films were produced in an in-situ photopolymerization in the cholesteric phase of the corresponding monomer mixture.
- a monomer mixture consisting of 50 mol% of a nematic component and 50 mol% of a chiral component and approximately 1 wt% of 2,2-dimethoxy-2-phenylacetophenone was dissolved in 1 ml of chloroform.
- a di- [4- (6-acryloyloxyhexyloxy) benzoic acid] -1,4-phenyl diester was used as the nematic component and a cholesteryl acrylate was used as the chiral component.
- the reaction solution was applied to a support, e.g.
- the coated substrate was heated to 115 ° C., the mesophase being formed in the monomer mixture.
- a good orientation was achieved by scraping the reaction solution onto the base, treating it with electric or magnetic fields, or by applying an orientation layer on the base beforehand.
- the applied film was then cured by UV light.
- the cured film had a violet color when illuminated vertically and under vertical supervision.
- reflection colors can be set in the film in the entire visible region of the spectrum and in the IR region, as can be seen from the table below.
- the coloring film was peeled off from the base with a blade-like tool, whereby scale-like structures were obtained.
- the scales were then crushed using an air jet mill (Alpine company); other thermally gentle mills for plastic parts can also be used.
- the ground material obtained was then sieved and a sieve fraction with an average size of approximately 30 ⁇ m was used for further processing.
- the interference pigments obtained were mixed with a clear lacquer in a ratio of 1: 7 to 1:20 parts by weight.
- a two-component topcoat based on polyurethane was used as the clearcoat; e.g. 2-component PU top coat Olli from BASF Lacke u. Paints or a varnish "Standox" from Herberts used.
- the effect paint was applied by a pneumatic spray process (tool: SATA) to a KW sunroof cover, which was provided with a black full paint finish of the designation DL 0404 by the applicant as a background.
- An electrostatic application method for the effect lacquer according to the invention with High-rotating spray bells also appear to be usable. After the application, the effect varnish was first dried and then hardened with thermal force.
- Another color film was made from di- [4- (6-acryloyloxy) hexyloxy] benzoic acid, 1,4- (2-methyl) phenyl diester as the nematic component and cholesteryl-2,3, (2-acryloyloxyethoxy) benzoate as the chiral component .
- the film was produced in accordance with the procedure given in the previous example, with the difference that the coated substrate was heated to 90 ° C.
- the interference pigments according to the invention form very narrow-band absorption curves for the different colors.
- the interference pigments have better chemical and physical compatibility with the customary paints with which they are mixed.
- the interference pigments according to the invention have a significantly higher crosslinking than those known hitherto, which is achieved in particular when using the difunctional nematic diacrylates and the difunctional chirai nematic diacrylates.
- the interference pigments produced have great mechanical stability and great color stability and show excellent adhesion and wetting ability.
- the starting components for the liquid-crystalline side chain polymers are also simple and inexpensive to produce.
