Claims
- 1. A liquid concentrate comprising:
- (I) a rosin based vehicle comprising:
- (A) at least about 52 percent by weight of the vehicle of at least one non-polymeric organic rosin ester;
- (B) at least about 0.1 percent by weight of the total concentrate of at least one surfactant having a surfactant demand which is met by a concentration of no more than about 20 percent by weight of the total concentrate; and
- (II) up to about 85 percent by weight of the total concentrate of at least one colorant or additive, wherein said concentrate flows readily by gravity and is characterized by a viscosity at 25.degree. C. under a shear stress of 12.5 thousand dynes/cm.sup.2 of about 5 to about 1500 poise.
- 2. The concentrate according to claim 1 wherein said non-polymeric rosin ester is liquid at 25.degree. C. or has a softening point from about 25.degree. C. up to about 80.degree. C.
- 3. The concentrate according to claim 1 wherein said non-polymeric rosin ester is a lower alkyl ester of rosin.
- 4. The concentrate according to claim 1 wherein said rosin based vehicle is substantially free of water.
- 5. The concentrate according to claim 4 wherein said rosin based vehicle contains less than about 0.1 percent by weight of the total concentrate of water.
- 6. A liquid concentrate prepared by a process that comprises:
- (1) blending a rosin based vehicle comprising (A) at least about 52 percent by weight of the vehicle of at least one non-polymeric organic rosin ester with (B) at least about 0.1% by weight of the total concentrate of at least one surfactant, to obtain vehicle (I); and
- (2) mixing (II) up to about 85 percent by weight of the concentrate of at least one colorant or additive with said vehicle (I) to obtain said concentrate.
- 7. The concentrate of claim 1 wherein said vehicle further comprises a low viscosity organic diluent.
- 8. The concentrate of claims 7 wherein said diluent comprises a mineral oil.
