An effect pigment includes a substrate; an outer layer disposed above the substrate; and particles disposed above the substrate and at least partially entrapped by the outer layer, the particles comprising quantum dots.

The present disclosure relates to methods and compositions comprising naturally occurring light absorbing molecules for preventing damages from light exposure. Specific embodiments of this disclosure include fluorescent proteins from Brachiostoma lanceolatum.

Optical effect pigment comprising a plurality of layers and a magnetic element, the layers can be arranged in two stacks of asymmetric layers or in a single stack of layers and comprise at least an absorber layer and at least a dielectric layer and can further comprise a reflector layer. The magnetic element presents a magnetisation which is out-of-plane, i.e. predominantly perpendicular to the plane of the pigment, which allows a deposition on the printing substrate whereby the face of the pigment lying up or down on the substrate can be predetermined. Such effect pigment has applications in many fields and specifically in security printing, where due to controlled deposition for instance a double-stack pigment will produce a different optical effect on each of its faces.

A pearlescent pigment for security purposes according to an embodiment of the present invention includes a single or a plurality of coating layers containing a metal oxide and an organic or inorganic fluorescent material. Since the pearlescent pigment for security purposes according to the present disclosure includes a fluorescent layer containing the organic or inorganic fluorescent material, it can be used as a pigment for security purposes due to its optical characteristics and can also provide effects such as magnetism, high color intensity, multiple colors, etc. Also, since the pearlescent pigment for security purposes has aesthetic benefit and security characteristic at the same time, it is economical, easy to use and applicable in various industries.
