Abstract
A diffractive pigment includes diffractive pigment, includes a stack including alternating layers of a high refractive index layer and a low refractive index layer, in which the high refractive index layer is a composition including an organic material and high refractive index inorganic nanoparticles; in which at least one layer of the stack is embossed. A method of making a diffractive pigment is also disclosed.
Claims20
A method of making a diffractive pigment, comprising:
- depositing alternating layers of a high refractive index layer and a low refractive index layer to form a stack, each layer of the stack including a dielectric material;
- and
- embossing at least one of the alternating layers to form an embossed surface, wherein a self-planarizing layer of the stack is deposited on the embossed surface using a liquid coating process, the self-planarizing layer having a first surface adjacent the embossed surface and a second surface opposite the embossed surface, the first surface conforming to the embossed surface and the second surface being planar.
A method of making a diffractive pigment, comprising:
- depositing alternating layers of a high refractive index layer and a low refractive index layer to form a stack, wherein one or more layers of the stack are deposited using a liquid coating process;
- and
- embossing at least one of the one or more layers of the stack deposited using the liquid coating process, wherein the embossing is done prior to a full curing of the at least one layer of the stack;
- wherein the high refractive index layer is a composition including an organic material and high refractive index inorganic nanoparticles;
- wherein at least one surface of at least one layer is non-embossed;
- and wherein the high refractive index inorganic nanoparticles have a value of refractive index (n), where n>1.65 at wavelength of 550 nm.
