Compositions, comprising platelet-shaped transition metal particles

Abstract

The present invention relates to compositions, comprising (A) platelet-shaped transition metal particles, wherein the number mean diameter of the platelet-shaped transition metal particles, present in the composition, is in the range of from 15 nm to 1000 nm, the transition metal is selected from silver, copper, gold and palladium, especially silver and copper, very especially silver; (B) one, or more reactive diluents (B); (C) one, or more oligomers (C); (D) one, or more photoinitiators (D); (E) at least a surfactant (E), which is a block copolymer, comprising at least a block A and a block B, wherein a) the block A comprises a1) monomer units (A1) derived from a compound selected from alkyl (meth)acrylates, alkyl (meth)acrylamides, or any mixture thereof, and a2) monomer units (A2) derived from a hydroxy group, or ether group containing alkyl (meth)acrylate; b) the block B comprises monomer units (B) derived from a compound selected from fluorinated (meth)acrylic esters of formula H2C═CR46(C(O)ORF-1)  (XX), wherein R46 is H, or a methyl group; and RF-1 is an organic residue containing a perfluorinated alkyl group; (F) optionally one, or more polymeric binders; (F) optionally one, or more solvents; and (H) optionally further additives. The coatings, obtained with said compositions, show one color, when observed in transmission and another color, when observed in reflection on both sides of the cured coating.
