Compositions having multiple responses to excitation radiation and methods for making same |
摘要 |
<p>The present invention is directed to a method for authenticating an article by using a regenerable composition comprising a plurality of forms having a plurality of responses, the method comprising: a) subjecting the composition to a first electromagnetic radiation (102) and generating a first response (103); b) transforming the composition from a first form (101') having a first response (103) to a second form (101") having a second response (106) upon application of electromagnetic radiation of wavelength (104); c) subjecting the composition to the first electromagnetic radiation (102) and generating the second response.</p> |
