Patent ID: 6977025

Claim:
A method of forming a monolayer of substantive particles the method comprising the steps of: (a) applying to a substrate a curable composition having substantive particles contained therein, the substantive particles having a particle size on at least one dimension thereof of at least 1 micrometer and being in two or more groups of different sizes; (b) applying a second substrate over the curable composition to confine the curable composition between the substrates; (c) applying pressure to the assembled substrates to produce a monolayer of particles of the different sizes; (d) exposing the substantive particle-containing curable composition to a source of energy suitable for effecting polymerization of the curable composition for a sufficient time to effect polymerization of a layer of the curable composition in the discrete regions having a thickness of no more than 50% of the height of the largest substantive particles; and (e) optionally, after separating the substrates, removing uncured curable composition.
