Low viscosity nonaqueous metal oxide particle dispersions

A nonaqueous dispersion comprising:

• a nonaqueous composition consisting of:
• an ester selected from the group consisting of:
• (i) a liquid ester of Formula I:
• wherein R and R1 are each a linear, branched, or cyclic alkyl;
• a linear, branched, or cyclic alkenyl;
• or a linear, branched, or cyclic alkynyl;
• wherein if one of R and R1 is a linear alkyl, the other of R and R1 is a branched, or cyclic alkyl;
• a linear, branched, or cyclic alkenyl;
• or a linear, branched, or cyclic alkynyl;
• (ii) a liquid ester of Formula II:
• wherein R2 is a branched alkyl, a linear or branched alkenyl, or a linear or branched alkynyl, R3 is a linear or branched alkyl, a linear or branched alkenyl, or a linear or branched alkynyl, and R4 is a linear or branched alkyl, a linear or branched alkenyl, or a linear or branched alkynyl;
• (iii) a liquid ester of Formula III:
• wherein R5 is a branched alkyl, a linear or branched alkene, or a linear or branched alkyne, R6 is a linear or branched alkyl, a linear or branched alkene, or a linear or branched alkyne, and R7 is a linear or branched alkyl, a linear or branched alkene, or a linear or branched alkyne;
• and
• (iv) combinations thereof;
• and
• a polyester having a terminal carboxylic acid functional group;
• and
• a plurality of metal oxide particles dispersed in the composition.
