The invention relates to a reflective feature, e.g., reflective security feature or reflective decorative feature, comprising a first element at least partially coplanar with a second element. The first element causes incident light to be reflected with a first intensity that varies as the angle of incidence changes relative to a surface of the reflective feature. The invention also relates to a direct write printing process for forming such a reflective feature from an ink comprising metallic nanoparticles.

Reflective features with co-planar elements and processes for making them

The present invention relates to a composition having a first response to a first electromagnetic radiation and, after intermediate exposure to a second electromagnetic radiation, a second response to the first electromagnetic radiation, different from the first response. In one aspect, the composition exhibits a regenerated first response to the first electromagnetic radiation after exposure to a third electromagnetic radiation.

Compositions having multiple responses to excitation radiation and methods for making same

The invention relates to reflective features formed from multiple inks. In one embodiment, the reflective feature includes a substrate having a first region and a second region, the first and second regions having different surface characteristics; a first reflective element disposed on the first region; and a second reflective element disposed on the second region, wherein the first reflective element is more adherent than the second reflective element to the first region. In another embodiment, the reflective feature includes multiple layers formed from different inks exhibiting enhanced reflectivity and/or durability. The invention is also to processes for forming these features, preferably through a direct write printing process.

Printable reflective features formed from multiple inks and processes for making them

The invention relates to reflective and non-reflective features formed from multiple inks. In one embodiment, the printed feature comprises a substrate having a first region and a second region, the first and second regions having different surface characteristics; a first printed element disposed on the first region; and a second printed element disposed on the second region, wherein the first printed element is more adherent than the second printed element to the first region. In another embodiment, the printed feature comprises multiple layers formed from different inks exhibiting enhanced durability. The invention is also to processes for forming these features, preferably through a direct write printing process.

Printable features formed from multiple inks and processes for making them

A particulate luminescent composition is disclosed that, when excited by electromagnetic radiation at a first frequency, emits electromagnetic radiation at a second frequency equal to or within 1500 cmof the first frequency. The luminescent composition comprises substantially spherical particles having a weight average particle size of less than about 10 &#x3bc;m and a particle size distribution such that at least about 90 weight percent of the particles are not larger than twice the average particle size.

Luminescent compositions, methods for making luminescent compositions and inks incorporating the same

Security films that are useful for pharmaceutical packaging. In particular, anti-counterfeiting security films having a luminescent composition on or in a fluoropolymer layer, which luminescent composition luminesces upon the application of ultraviolet radiation in the 200 nm to 300 nm range, in which the luminescent component is optionally and preferably not viewable to the unaided eye. The films are particularly useful for the formation of anti-counterfeiting blister packaging in compliance with FDA regulations.
