| 摘要 |
The invention relates to a method for producing a multilayer structure comprising a separating layer. According to said method, an initial multi-layer structure (1) is produced, said initial structure consisting of a base substrate (2), a surface substrate (5) and, between the base substrate and the surface substrate, an absorbent layer (3) that can absorb a luminous power flux in at least one region, and a liquefiable intermediate layer (4) comprising impurities in at least one region, said impurities having a segregation coefficient lower than one in relation to the material forming said intermediate layer. The initial structure (1) is subjected to said luminous power flux in the form of at least one pulse over a determined duration, the power flux being regulated in such a way as to produce the liquefaction of at least part of the intermediate layer (4) under the effect of the propagation of the thermal energy, such that, as a result of the initial presence of said impurities, at least one characteristic and/or at least one property of the intermediate layer (4) is modified after the at least partial solidification of the intermediate layer, such that said intermediate layer at least partially forms a separating layer. |
