Abstract
A tinting composition containing a colorant component is disclosed. In addition, a method of improving the viscosity stability of a composition upon the addition of a colorant component employing an associative thickener, a macromolecular compound having a hydrophobic cavity, a dispersing resin and combinations thereof is disclosed.
Claims8
A method of improving the viscosity stability of a coating composition upon the addition of a colorant component, comprising the steps of:
- a) providing a base paint;
- and
- b) adding to said base paint, a tinting composition comprising:
- i) at least one colorant composition;
- and
- ii) from 0.05 to 15% dry weight of at least one macromolecular compound having a hydrophobic cavity, based on the weight of said at least one colorant composition.
