Description
15 20 25 30 35 81-03830-9 lätt växelverkar med laserstrálen och därvid antingen genom- gàr färgförändring eller volymförändring eller båda delarna. 15 20 25 30 35 81-03830-9 easily interacts with the laser beam and thereby undergoes either color change or volume change or both parts.
Hos en utföringsform av uppfinningen bildas skum eller annan porös hårdnande massa. Likaså är det enligt uppfinningen möjligt att välja materialet i reaktionsskiktet så att det vid reak- tionen med laserstràlen avges eller bildas ämnen som reagerar med de av laserstrålens energi uppvärmda kantomrâdena hos ytterskiktet och att denna reaktion är så vald att en kontrast- förändring därvid sker. En sådan lämplig reaktion är att det bildas ämnen som etsar eller etsar bort det metalliska ytter- skiktets kantomràden.In one embodiment of the invention, foam or other porous hardening mass is formed. It is also possible according to the invention to select the material in the reaction layer so that during the reaction with the laser beam substances are emitted or formed which react with the edge areas of the outer layer heated by the energy of the laser beam and that this reaction is chosen so that a contrast change occurs. Such a suitable reaction is that substances are formed which etch or etch away the edge areas of the metallic outer layer.
Genom att välja ändamålsenligt material i reaktions- skiktet kan man uppnå att laserstrålen smälter och delvis ger upphov till viss förângning i smältan som därvid expanderas och pressas upp. I vissa fall visar sig smältan kunna flyta ut över ytterskiktets uppvärmda kantområden.By selecting appropriate material in the reaction layer, it can be achieved that the laser beam melts and partly gives rise to a certain evaporation in the melt, which is thereby expanded and pressed up. In some cases, the melt is found to be able to flow out over the heated edge areas of the outer layer.
I en annan utföringsform av uppfinningen låter man kom- binationer av effekttäthet lasern och materialet i reaktions- skiktet vara sådant att det sistnämnda förkolnas. Vidare är det ibland ändamålsenligt att låta reaktionsskiktet bestå av två skikt som har sådan sammansättning att de under inverkan av laserstràlen ger den önskade reaktionen men som eljest ej reagerar med varandra.In another embodiment of the invention, combinations of power density laser and the material in the reaction layer are allowed to carbonize the latter. Furthermore, it is sometimes expedient to let the reaction layer consist of two layers which have such a composition that under the influence of the laser beam they give the desired reaction but which otherwise do not react with each other.
' Uppfinningen beskrivs vidare nedan i anslutning till de bifogade figurerna l-4 som samtliga visar olika utförings- former av den föreliggande uppfinningen.The invention is further described below in connection with the accompanying figures 1-4, all of which show different embodiments of the present invention.
I fig. l visas i förstoring enligt uppfinningen i tvär- snitt ett metallsubstrat 2 som är laminerat med ett reaktions- skikt 3 och ett metalliska ytterskikt 4. En laserstråle l är vid gravyren fokuserad i eller strax över ytterskiktet 4.Fig. 1 shows in magnification according to the invention in cross section a metal substrate 2 which is laminated with a reaction layer 3 and a metallic outer layer 4. A laser beam 1 is focused at the engraving in or just above the outer layer 4.
I fig. 2 visas i förstoring i genomskärning ett ämne enligt uppfinningen som har två reaktionsskikt 6, 7, vilka reagerar med varandra till ett hårdnande skum när de träffas av laserstrålen. Den uppsvällda massan kan även flyta ut över ytterskiktets uppvärmda kantområde. l fig. 3 visas i förstoring i genomskärning hur reak- tionsskiktet som därvid dels ändrat färg, dels ändrat volym (nedåt) vilket ger såväl relief som färgkontrastverkan. 8103830-9 I fig. 4 visas i större förstoring ett ämne enligt upp- finningen där det vid reaktionen bildats ämnen som frätt bort kantomràdena av ytterskiktet och därvid frilagt delar av reaktionsskiktet. Genom val av färg hos ytterskikt och reak- tionsskikt erhålls god färgkontrast.Fig. 2 shows in magnification in cross section a substance according to the invention which has two reaction layers 6, 7, which react with each other to a hardening foam when they are hit by the laser beam. The swollen mass can also flow out over the heated edge area of the outer layer. Fig. 3 shows in magnification in section how the reaction layer, which thereby partly changed color, partly changed volume (downwards), which gives both relief and color contrast effect. Fig. 4 shows in a larger magnification a substance according to the invention in which substances are formed during the reaction which corrode the edge areas of the outer layer and thereby expose parts of the reaction layer. By choosing the color of the outer layer and reaction layer, good color contrast is obtained.
