Inkjet printing is employed using liquid inks that contain one or more reactive agents that react in situ to form dielectric films on a substrate on which conductive inks or ink receiving inks have previously been printed. At least one of the reactive materials is blocked, so that the reaction does not occur until the material is unblocked by the application of energy during the final film curing process. Illustrative reactive materials are materials with functional groups capable of reacting with active hydrogen, such as isocyanate group, and a second material with functional groups containing active hydrogen, such as hydroxyl. Typical examples are polyols or polyacrylic acids. When additional humectant material is in the ink, a small amount of excess blocked isocyanate is added to the ink to react with additional humectant materials.
