Abstract
Disclosed herein is a dispersion comprising a liquid or semi-solid continuous phase, a dispersed solid phase comprising a plurality of organic, inorganic or inorganic-organic particles, and an alkyl ketal ester having the structure wherein a is 0 or an integer of 1 to 12, specifically 1 to 6, more specifically 1 to 4; b is 0 or 1; R2 is a divalent C1-8 group optionally substituted with up to 5 hydroxyl groups; and R1 is C1-6 alkyl, and wherein at least a portion of the alkyl ketal ester is present in the continuous phase, on a surface of at least some of the dispersed particles, or a combination thereof.

A dispersion comprising
- a liquid or semi-solid continuous phase,
- a dispersed solid phase comprising a plurality of organic, inorganic or inorganic-organic particles, and
- an alkyl ketal ester having the structure
- wherein
- a is 0 or an integer of 1 to 12;
- b is 0 or 1;
- R2 is a divalent C1-8 group optionally substituted with up to 5 hydroxyl groups;
- and
- R1 is C1-6 alkyl, and
- wherein at least a portion of the alkyl ketal ester is present in the continuous phase, on a surface of at least some of the dispersed particles, or a combination thereof.
A composition, comprising
- a plurality of solid particles;
- and
- an alkyl ketal ester at least partially coating at least some of the particles, the alkyl ketal ester having the structure:
- wherein
- a is 0 or an integer of 1 to 12;
- b is 0 or 1;
- R2 is a divalent C1-8 group optionally substituted with up to 5 hydroxyl groups;
- and
