Abstract
There is disclosed a print construction comprising: (a) a printing substrate having an image-receiving surface; (b) a receptive layer, at least partially covering said image-receiving surface, and having a particle reception surface distally disposed to said image-receiving surface, said receptive layer optionally having a thickness of at least 1000 nanometer (nm); and (c) a plurality of individual particles adhered to said particle reception surface, and forming a monolayer thereon, the features of which are described herein.

A print construction comprising:
- (a) a printing substrate having an image-receiving surface;
- (b) a receptive layer, at least partially covering said image-receiving surface, and having a particle reception surface distally disposed to said image-receiving surface, said receptive layer having a thickness of at least 1000 nanometer (nm);
- and
- (c) a plurality of individual metal particles adhered to said particle reception surface and forming a monolayer thereon, wherein an outer surface of said metal particles is hydrophobic;
- wherein a number-averaged aspect ratio (ASPavg) of said plurality of individual metal particles is defined by:
- ASPavg=Lavg/Havg
- wherein Lavg is a number-averaged maximum long dimension of said plurality of individual metal particles;
- wherein Havg is a number-averaged maximum thickness of said plurality of individual metal particles;
- and wherein said plurality of individual metal particles exhibit at least one of the following structural properties:
- (A) said number-averaged maximum long dimension (Lavg) is at most 800 micrometers;
- (B) said number-averaged maximum average thickness (Havg) is at most 1200 nm;
- (C) said number-averaged aspect ratio (ASPavg) is at least 1.5:1;
- and
- wherein said monolayer has an optical surface coverage ratio of at least 20%.
