Quantum dot ink formulation for heat transfer printing applications

摘要

A method of printing comprises: using an ink composition including at least one population of quantum dots; depositing the ink composition in a first substrate to form an image and transferring the image to a second substrate; the transfer may include the application of heat and pressure to the substrates; the first substrate may be a thermal transfer sheet; the ink may be deposited by ink jetting; doctor blading or screen printing. Also described are quantum dot ink formulations for heat transfer printing including a solvent and a binder or wax. The methods and materials can be used for anti-counterfeiting applications.
