Thermoplastic resin composition for light reflector, formed article for light reflector, light reflector, and method for producing formed article for light reflector

Thermoplastic resin composition for a light reflector such as a housing, reflector, and extension of an automotive lamp, and a lighting fixture. The composition contains 2 to 45 parts by mass of an inorganic filler treated with a fatty acid type surface treating agent and has an average diameter of not more than 3 m, per 100 parts by mass of a thermoplastic resin. The housing reflector made from such thermoplastic resin composition shows excellent surface smoothness, surface luster and surface image clarify.

The invention relates to an infrared reflecting film comprising a flexible polymer substrate; a heat-mirror stack on the substrate, said heat-mirror stack comprising a first dielectric oxide layer, a second dielectric oxide layer and a silver-containing layer between the first and second dielectric oxide layers; and an optical stack on the heat mirror stack, said optical stack comprising alternating layers of at least one layer of a first type and at least one layer of a second type, wherein each layer of the first type has a refractive index measured at 550 nm of 1.6 or less and each layer of the second type has a refractive index measured at 550 nm of 2.3 or more.

Substrate-transferred stacked optical coatings

A method for manufacturing hybrid optical coatings and hybrid mirror assemblies, including: a) providing a first optical coating having layers of alternating high and low refractive indices of crystalline materials on a first host substrate via an epitaxial growth technique; b) providing a second optical coating having layers of alternating high and low refractive indices of dielectric materials on a second host substrate via a physical vapor deposition (PVD) technique; c) directly bonding the first optical coating to the second optical coating; and d) removing the first host substrate.
