Abstract
A photocurable silver composition is provided which comprises an ultraviolet light curable organic mixture, a photoinitiator, a silver powder, and a silver flake composition. The silver flake composition comprises at least 20% of the weight of the silver powder. The disclosed compositions may be used to produce silver-containing coatings on a variety of different substrates. Related methods are provided.
Claims22
A method for depositing a silver coating on a substrate, the method comprising:
- a first step of applying to the substrate a composition comprising:
- an aliphatic acrylated urethane oligomer;
- an acrylated epoxy oligomer;
- an isobornyl acrylate monomer;
- a photoinitiator;
- silver powder;
- and
- silver flakes in an amount of at least 20% relative to the weight of the silver powder;
- and
- a second step of photocuring by exposure to light of a wavelength effective to cure said composition.

A photocurable silver composition consisting essentially of:
- a photocurable organic mixture;
- a photoinitiator;
- silver powder;
- and
- silver flakes in an amount of at least 20% relative to the weight of the silver powder, wherein the photocurable organic mixture comprises an aliphatic acrylated urethane oligomer and the photocurable silver composition when illuminated with ultraviolet (UV) light cures into a silver coating.
