Abstract:
The present invention relates to trifluoromethylpyridone-based methine and azamethine dyes of the formula I ##STR1## a process for their thermal transfer, a process for dyeing or printing synthetic materials and their use.
Abstract:
The invention calls for a discrete material (1) such as a gas, a liquid or a living being, to be exposed to electromagnetic radiation from a large-area irradiator (2) causing the molecules to resonate at their natural frequency and hence to become warmer. In order to lower the temperature of the material (1), the radiant energy emitted by its is extracted via a receive antenna (5), resulting in a loss in energy and hence cooling of the material. Working in an enclosed fluid-filled space, the fluid can also be included, by suitable choice of radiation spectrum, in the resonance interaction producing the warming or cooling effect.

Abstract:
Quaternized azo dyes whose diazo components are derived from a five-membered nitrogen-containing aromatic aminoheterocycle and whose coupling components are derived from the aniline series are prepared by reacting to corresponding neutral dye-bases with an alkylating agent in .gamma.-butyrolactone as inert diluent.
