Abstract:
The invention relates to a process for preparing a dichromatic material, in the form of a translucent film, comprising monodisperse nanoparticles formed of gold and optionally of a noble metal chosen from platinum, palladium, silver and copper, and at least one organic macromolecule chosen from proteins, polysaccharides and synthetic polymers; said dichromatic material; and the uses thereof.

Claim (Index 14):
Process according to  claim 12 , characterized in that the seeds are gold seeds and step A) comprises:\n a substep A 1 ) of heating to boiling point a solution S 1  comprising at least one gold salt in which the gold is in the (+III) or (+I) oxidation state, the molar concentration of [Au 3+ ] or [Au + ] gold ions in said aqueous solution S 1  ranging from 5\u00d710 \u22125  mol/l to 10 \u22122  mol/l, a substep A 2 ) of mixing the solution S 1  from substep A 1 ) with a solution S 2  comprising at least one reducing agent and optionally a stabilizer, the molar concentration of reducing agent in said solution S 2  [Reducing agent] ranging from 5\u00d710 \u22125  mol/l to 5\u00d710 \u22121  mol/l, it being understood that the molar ratio: number of moles of reducing agent/number of moles of Au 3+  or Au +  gold ions ranges from 0.1 to 20, a substep A 3 ) of maintaining the heating to boiling point of the mixture from substep A 2 ) until the gold (III) or the gold (I) has been completely reduced to gold (0), and a substep A 4 ) of cooling to ambient temperature in order to obtain said colloidal suspension comprising gold seeds.
