Abstract: The invention relates to storage-stable pigmented formulations containing isocyanate groups, comprising at least one pigment a., at least one component b. containing isocyanate groups, at least one wetting agent and/or dispersant c., at least one isocyanate group-containing grinding resin d. and optionally solvents, wherein the formulation has a viscosity increase of less than 500% after storage at 50° C. over a period of at least 3 days. The invention also relates to the preparation of such formulations and to the use thereof.

Abstract: Electronic circuit with a controllable switch, in particular a semiconductor switch, and a control device for controlling the semiconductor switch, wherein the control device is designed to activate the semiconductor switch depending on the voltage applied to a load path at a first time range of a specifiable, preferably negative, half-wave of a periodic electrical voltage that can be applied to the load path of the semiconductor switch and to enable a deactivation of the semiconductor switch depending on the voltage being applied to the load path initially at a second time range following the first time range.
