Abstract:
The invention relates to a hot melt inkjet ink composition, the hot melt inkjet ink composition being solid at room temperature and liquid at an elevated temperature, the hot melt inkjet ink composition comprising an acidic resin and a crystalline material. The invention relates further to the use of the hot melt inkjet ink composition as an etch resist and to a process for preparing an electrically conductive circuit on a support layer using the hot melt inkjet ink composition.
