摘要:
Disclosed are laser markings on a document of value and methods of preparing the same which are based on the interaction of the laser radiation with the printing-ink employed.
摘要:
The present invention relates to a security pigment having an intrinsic hidden and/or forensic security feature, consisting of a transparent inorganic matrix and at least one particulate material embedded in the matrix, to the use of a security pigment of this type for the pigmentation of paints, coatings and the like, and to a method for the detection of a security pigment of this type.
摘要:
The present invention relates to a process for increasing the counterfeiting protection of high-value products, documents of value and security documents by means of uncopyable security features which are transferred into the respective material with the aid of laser technology.
摘要:
The invention relates to novel etching media in the form of etching pastes for etching selected areas or the entire area of silicon surfaces and layers, in addition to the use of said media.
摘要:
The present invention relates to a novel printable etching medium having non-Newtonian flow behavior for the etching of surfaces in the production of solar cells and to the use thereof. In particular, the invention relates to corresponding particle-containing compositions by means of which extremely fine structures can be etched very selectively without damaging or attacking adjacent areas.
摘要:
The present invention relates to particle-containing etching media in the form of etching pastes which are suitable for the full-area or selective etching of extremely fine lines or structures in silicon surfaces and layers and in glass-like surfaces formed from suitable silicon compounds. The present invention also relates to the use of the pastes according to the invention in processes for etching surfaces of this type.
