Abstract
Abstract The object of the invention is a solution of one or more sublimable disperse dyestuffs in organic solvents. These solvents consist of at least one aliphatic hydrocarbon containing chlorine, mixed with a minor amount of hexamethylphosphorotriamide. The solutions according to the invention are particularly suitable for the manufacturing of felt tip markers or pens for decorating woven, non-woven or knitted materials by hot transfer.
