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 15):
Process according to  claim 12 , wherein the seeds are gold seeds and step B) comprises:\n a substep B 1 ) of heating to boiling point a solution S 3  comprising at least one gold salt in which the gold is in the (+III) or (+I) oxidation state, the concentration of [Au 3+ ] or [Au + ] gold ions in said solution S 3  ranging from 10 \u22124  mol/l to 0.1 mol/l, a substep B 2 ) of mixing the solution S 3  from substep B 1 ) with the colloidal suspension comprising seeds as obtained in step A) or in substep A 4 ), it being understood that the molar ratio defined by the number of moles of Au 3+  or Au +  gold ions of the solution S 3 /the number of moles of Au 0  gold of the colloidal suspension of gold seeds ranges from 5 to 1000, a substep B 3 ) of mixing a solution S 4  comprising at least one reducing agent and optionally a stabilizer with the mixture from substep B 2 ), the concentration of reducing agent in said solution S 4  [Reducing agent] ranging from 2\u00d710 \u22125  mol/l to 2 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 10, a substep B 4 ) of maintaining the heating to boiling point of the mixture from substep B 3 ) until the gold (III) or the gold (I) has been completely reduced to gold (0), and a substep B 5 ) of cooling to ambient temperature in order to obtain said colloidal suspension S 0 .
