Fluoropolymer blend anti-reflection coatings and coated articles
First Claim
1. The method of making an anti-reflection coated body having a reflective surface which comprises applying a solution of a polymeric composition comprising a blend of(a) from about 1 to about 95 percent by weight of amorphous fluoropolymer, with(b) from about 5 to about 99 percent by weight of a fluorinated copolymer having a polymer chain composed of
units, whereins, t and u represent weight proportions of the respective X, Y and Z units, and have values within the ranges ofs=from about 0.5 to about 0.995;
t=from about 0.0025 to about 0.4975; and
u=from about 0.0025 to about 0.4975;
with the sum of s+t+u being 1;
X represents units of the composition ##STR8## wherein R1 is H, --CH3, or mixtures thereof;
p is 1 or 2;
n is an integer of from about 1 to about 40;
Y represents units of the composition ##STR9## wherein R2 is H, --CH3 or --CH2 COOH;
Z represents units of the composition ##STR10## wherein R3 is H, --CH3, or CH2 COOCm H2m+1, wherein m is an integer of from about 1 to about 4, andR4 is an alkylene bridging group, straight chain, branched or cyclic, having from 1 to about 8 carbon atoms;
wherein the X, Y and Z units may be arranged in any sequence.
