    摘要： Interference pigment flakes and foils are provided which have luminescent and color-shifting properties. The pigment flakes can have a symmetrical coating structure on opposing sides of a core layer, can have an asymmetrical coating structure with all of the layers on one side of the core layer, or can be formed with encapsulating coatings around the core layer. The coating structure of the flakes and foils includes a core layer, a dielectric layer overlying the core layer, and an absorber layer overlying the dielectric layer. A luminescent material is incorporated into the flakes or foils as a separate layer or as at least part of one or more of the other layers. The pigment flakes and foils exhibit a discrete color shift so as to have a first color at a first angle of incident light or viewing and a second color different from the first color at a second angle of incident light or viewing. The pigment flakes can be interspersed into liquid media such as paints or inks to produce colorant materials for subsequent application to objects or papers. The foils can be laminated to various objects or can be formed on a carrier substrate.

    摘要： The present invention is directed to lithographic printing plates that are suitable for imaging by laser discharge using laser ablation. The lithographic printing plates according to the present invention comprise a vacuum deposited polymeric layer comprising polyvinylpyrrolidone having a thickness of up to about 6000 Angstroms, an absorbing layer underlying the first layer that absorbs infrared radiation and has a thickness in a range between about 100 and about 500 Angstroms, and a substrate underlying the absorbing layer. The polymeric layer and the substrate exhibit different affinities for at least one printing liquid selected from the group consisting of ink and an adhesive fluid for ink.
