Abstract
An agent for dyeing keratinous material, in particular human hair, is disclosed. The agent is a colorant composition comprising at least one amino-functionalized silicone polymer, at least one color-imparting compound, and at least one organic carbonic acid ester. A process (method) for dyeing keratinous material with the agent is also disclosed. The process includes applying a colorant comprising the agent to the keratinous material, exposing the keratinous material to the agent for an exposure time sufficient for the color-imparting compound to act on the keratinous material, and rinsing out the keratinous material with water.
