Claim 12:
13. A method for forming a multilayer coating comprising:
a) combining a solvent, a pigment and a brush block copolymer (BBCP) to form a mixture, wherein the BBCP is a BBCP of Formula IC:, , wherein
Rx is —(C2-C6)alkyl-OC(═O)G1 wherein G1 comprises polyacrylate, polymethacrylate or polylactic acid;
Ry is —(C1-C8)alkyl-G2-G3 wherein G2 is —C(═O)O— or a nitrogen heterocycle, and G3 comprises polystyrene, polyacrylate, polydimethylsiloxane, polyether, polymethacrylate, or polylactic acid;
R1 is unbranched alkyl;
R2 is branched alkyl;
a and b are each independently 0 to about 1000; and
x and y are each independently 1 to about 1000;, wherein the ratio of x:a is 1:0 to about 1:3 and the ratio of y:b is 1:0 to about 1:3;
b) applying a first layer of the mixture to a substrate;
c) drying the first layer to form a film; and
d) applying a second layer comprising a topcoat to the film wherein the topcoat is an optical adhesive or ultraviolet curable resin;
wherein the film and the second layer form the multilayer coating on the substrate.
