  The synthesis and electronic absorption spectra of 3-phenyl-3(4-pyrrolidino-2-substituted phenyl)-3H-naphtho[2,1-b]pyrans: further exploration of the ortho substituent effect

  摘要：

  Introduction of a substituent into a sterically demanding 2-position of a 3-(4-pyrrolidinophenyl) ring of a 3,3-diaryl-3H-naphtho[2,1-b]pyran results in the generation of an additional short wavelength absorption band leading to organic photochromes that appear as dull shades of orange and red.

  This invention generally relates to a composition, an apparatus, and a method for authenticating a product. In particular, the invention relates to an ink composition for marking a product with a continuous inkjet printer. The composition includes a visible ink and a UV, visible, and/or IR marker. Marking includes depositing the ink composition on the product with the continuous inkjet printer. A marked product is authenticated with a hand-held apparatus that activates the marker in the mark with UV radiation. Activation of the marker in the mark changes the absorbance/reflectance of visible radiation by the mark without changing the visual appearance of the mark. Authenticity of the product is assessed by a change in absorbance or reflectance of visible radiation by the mark after activation of the mark.
