Abstract
Process for the manufacture of a colour-marked object by irradiating the surface of the object with laser light, characterized in that the object, at least at the location where the marking is applied, consists of a plastic composition which contains at least three light-absorbing components which exhibit a maximum in their light absorption spectra at different wavelengths and lose their light-absorbing capacity under the influence of laser light, with the marking being applied in the form of matrix dots by irradiating the object's surface at the location of the matrix dots with laser light of such wavelength and intensity and for such duration that at least one of the light-absorbing components has wholly or partially lost its light-absorbing capacity.
Description
The present invention relates to adopt laser that body surface is carried out the method that the radiation manufacturing has the object of colour-coded (colormarked).
From this as can be known method of WO94/12352.This patent application discloses a kind ofly carries out the method that radiation makes colour-coded to body surface under optional conditions.
The shortcoming of this known method is that the gained color can not freely be selected, but forms at random.And, only can obtain limited varicolored mark.
The purpose of this invention is to provide a kind of method that does not have above-mentioned shortcoming.
Amazingly be, adopt following object to reach this purpose, this object applies the position of mark at least at it, be made up of the plastics composite that contains at least three kinds of extinction components; These extinction components have a maximum in its absorption spectrum under different wave length, and lose its extinction ability under laser action; Described mark applies with the form of matrix point (matrix dot), and adopts wavelength, and intensity and radiated time all should be and make at least a extinction component lose the laser of its extinction ability wholly or in part, and the body surface of matrix point position is carried out radiation.
Can access the mark that can freely determine color according to the method, this mark can contain different colours, and the mark of this different colours can obtain on same plastic composition surface.And, this mark that on same plastic composition surface, obtains even many different colors can be arranged.
Before the color absorption component lost its extinction ability wholly or in part, the matrix point presented the spectral color that the color absorption component is absorbed.
Having understood thoroughly the extinction component is to have colored component, for example: dyestuff and pigment.Also understand thoroughly the extinction component and do not comprise white or black color component, for example: titanium dioxide, chalk, barium sulphide, carbon black or iron sulfide.
The most important thing is that the extinction component does not lose or lose hardly its extinction ability under normal daylight.For this reason, the colour-stable degree that the extinction component should have in wool scale (Wool scale) (pressing DIN54003), is at least 5, more preferably at least 7, be preferably more than 7 again.
The example of the extinction component that is suitable for is Irgalith
Rubine 4BP, a kind of pinkish red coloring pigment; Irgalith Blue LGLD, a kind of cyan coloring pigment; Or Cromopthal
Yellow 6G and Cromopthal Yellow 3G, two kinds of yellow coloring pigment.By the way, most of extinction components lose its all or part of extinction ability by laser emission.
The present invention can be applied to the matrix point on the surface with straightforward procedure.
Laser with specific wavelength carries out the extinction ability drop that radiation makes preliminary election extinction component: the surface of radiation position will reflect the component of discussing can not resorbent color.The brightness of institute's reflection colour can improve by intensity or the prolongation radiated time that increases laser.
The mark of purpose color can form by applying many matrix points from the teeth outwards.
Also can be applied to the matrix point of different colours on the surface side by side.For observer, the surface color of matrix point position is a kind of colour mixture, because the color of matrix point is to project on the naked eyes by colour mixture.This color mixing method of the color for the treatment of colour mixture of settling side by side is called distribution method (partitive method).Colour mixture is by the surface area ratio and the decision of colour brightness ratio of matrix point.By this method, can form many colour mixtures.
The most important thing is that herein the centre-to-centre spacing between matrix point is little that naked eyes can not be told single matrix point.News picture also is painted by this way.
As known, the matrix point of at least three kinds of different colours be applied on the surface can obtain good result from color printing.This can adopt at least three kinds of different wavelength of laser that radiation is carried out on the surface and realize that in this process, one of at least three kinds of extinction components have lost its extinction ability under each wavelength wholly or in part.By this method, use at least three kinds of color relations and can form many other colors by mixing an amount of color.
Can carry out colour mixture in many ways.The method of finishing colour mixture is, for example, changes the colour brightness each other of matrix point, for example, the matrix point long than other matrix point of particular color carried out radiation.In addition, also can change different colours total area ratio each other, the method that is adopted is, for example, prepares a kind of matrix point big than other matrix point, perhaps forms the matrix point of the number a kind of color many than the matrix point of other color.The matrix point can be circle or square, still, for example in order to be full of the surface better or to increase surperficial total reflection, also can be, and is for example, leg-of-mutton or linear.
Color characteristic is, according to ASTM standard E308, at first measure the tristimulus values (tristimulus values) of this color, in above-mentioned standard, narrated then, calculate chromaticity coordinate thus, the position (10 ° observation person) of decision color in CIE D65 chromatic graph.So, chromatic graph is the diagram of all colours in the visible range.
Distribute hybrid technology can form following color, this color is located at the zone between the point of at least three kinds of different colours of expression matrix point in the chromatic graph in chromatic graph.These points formed should the zone the peak.
The method that obtains more different colours of the present invention comprises, applies the matrix point in all or part of overlapping mode.This colour mixture technology is called the mixing of losing lustre.
Preferably, surface color mixes decision by the losing lustre of matrix point of at least three kinds of different colours.Mix the color gamut send from losing lustre greater than distributing the situation of mixing, in chromatic graph, be located at the outside in the zone between the point of at least three kinds of different colours representing matrix point in the chromatic graph because of the color of its formation.
Plastics composite can comprise any thermosetting or thermoplastic or elastomer in principle.The plastics that the plastics composite of narrating in WO94/12352 can comprise are particularly suitables.
Preferably, so select the extinction component, make the zone between the point of at least three kinds of different colours in chromatic graph, representing matrix point cover at least 10% of this graph region.
Preferably, this zone covers 30% of this figure at least, more preferably covers at least 75% of this figure.
Can determine at an easy rate that by experiment it is used that radiation is carried out on the surface, so that make predetermined extinction component lose the Wavelength of Laser of its extinction ability.
Preferably, the optical maser wavelength that radiation uses being carried out on the surface is that under this wavelength, maximum appears in the absorption spectrum of the extinction component that loses its extinction ability.By this method, can obtain good color selectivity and brightness.
Preferably, method of the present invention adopts one or more masks to carry out.This class mask transmissive in treating the surface location of radiation, and can not transmission in the non-surface location for the treatment of radiation.Adopt different masks and different wavelength of laser that continuous radiation is carried out on the surface, the matrix point of different colours easily is applied on the surface fast.
The advantage of this method is that the size of matrix point is determined by mask, rather than determines that by the diameter of laser beam therefore, radiation can be carried out with large diameter laser beam in the surface.As a result, radiated time is shorter.
Preferred method of the present invention is implemented with variable mask.
The mask that the preferred LCD of use (liquid crystal display) screen is made.
More preferably use PDLCD (PDLC demonstration) mask, its attendant advantages is that it does not absorb, but the scattering laser beam of transmission not, mask can not heat up like this.
The advantage of this class mask is that desirable mask can be with the computer manufacturing on LCD screen and PDLCD screen.Can carry out radiation to the surface by mask subsequently.Thereafter, another mask of compensation on the screen of same position.Like this, avoided issuable position deviation.Another advantage is to change different masks fast.
Be that by at least three mask while radiant matter surfaces that the position is adjacent one another are, different wavelength of laser is connected on the mode that projects to body surface above with one in mask video mask is carried out radiation with laser aid if implement method of the present invention.That will not obtain very well results.Its advantage be body surface in once-through operation by different mask radiation.If mask is variable in this operation, additional advantage is to apply not isolabeling fast in turn so.From the similar as can be known mechanism of video projection.
Also can adopt the controlled laser beam of variable intensity to implement this method.With regard to the shape and colour brightness for the treatment of the radiation object, this implementation method has big flexibility.
In addition, the laser aid with wavelengthtunable also is optimal, owing to can adopt different wavelength of laser that radiation is carried out on the surface by enough laser aids.
Preferably, laser instrument can be launched the light of the different wave length that is complementary with the absorption spectrum maximum of different extinction components.Adopt a laser instrument just can form all possible color like this.
More preferably, use the laser aid that has merged at least three kinds of laser beams of different wave length in a fiber, this device can irrespectively change the intensity of every kind of light beam with other light beam.Its advantage is, can adopt a kind of recombination laser Shu Rongyi that can send all colours that body surface is carried out radiation.Consequently, with regard to the shape of the number of color that can select and the mark that applies, has very high flexibility.
