Fluoropolymer blend anti-reflection coatings and coated articles

A solid body having a reflective surface, having deposited thereon as an anti-reflection coating a layer 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
• --X.sub.s --Y.sub.t --Z.sub.u --
• units, wherein
• s, t and u represent weight proportions of the respective X, Y and Z units, and have values within the ranges of
• s=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 R.sup.1 is H, --CH.sub.3, 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 R.sup.2 is H, --CH.sub.3 or --CH.sub.2 COOH;
• Z represents units of the composition ##STR10## wherein R.sup.3 is H, --CH.sub.3, or CH.sub.2 COOC.sub.m H.sub.2m+1, wherein m is an integer of from about 1 to about 4, and
• R.sup.4 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, said amorphous fluoropolymer retainting its amorphicity in said blend and not phase separating during or after any curing.
