The present invention is directed towards an electrodepositable coating composition comprising a film-forming binder and electrically conductive particles, wherein the electrically conductive particles are present in an amount of at least 25% by weight, based on the total solids weight of the electrodepositable coating composition. The present invention is also directed towards methods of coating a substrate, coatings, and coated substrates.

Electrodepositable coating compositions and electrically conductive coatings resulting therefrom

A radiation-scattering composition, comprising a plurality of colloidal crystals or aggregates of colloidal crystals, each said crystal comprising radiation reflecting particles in a colloidal array and radiation absorbing particles dispersed in the crystals. The composition scatters radiation in a wavelength band in substantially all directions and absorbs radiation.

Highly reflective crystalline colloidal arrays with radiation absorbing particles

A reflective material comprising a multilayered array of particles encapsulated by a matrix material, the reflective material defining a primary surface, the reflective material exhibiting: (i) visible retroreflection of incident radiation, wherein a wavelength of visible retroreflected radiation decreases from a first visible wavelength at a first angle to the primary surface to a second, shorter wavelength of visible retroreflected radiation as the viewing angle to the primary surface increases; and (ii) Bragg diffraction of the incident radiation, wherein the wavelength of radiation Bragg diffracted normal to the primary surface is longer than the wavelength of visible radiation, such that no visible radiation is retroreflected or Bragg diffracted in a direction normal to the primary surface.

Retroreflective colorants

A dispersion of monodisperse similarly charged particles, the monodisperse particles having a maximum particle size dispersity of 10% and each particle having a surface with a minimum surface charge density of 1 &#x3bc;C/cmand comprising pendant steric stabilizing groups.

In situ assembled crystalline colloidal arrays
