Energy curable compositions comprising polyols, and any blend of ethylenically unsaturated monomers and oligomers. The polyols of the invention are essentially free of any ethylenically unsaturated groups. It is preferred that the polyol substances according to the invention have greater than one hydroxy group and preferably have boiling points in excess of 170 C. The compositions of the invention are particularly useful for the printing or coating of food packaging and may be applied via any printing or coating method, although inkjet printing is a preferred method.

Electron beam curable compositions comprising poly(alkylene oxide) containing substances, and any blend of ethylenically unsaturated monomers and oligomers. The poly(alkylene oxide) components of the said substances may include poly(ethylene glycol)s, poly(propylene glycol)s and higher poly(alkylene oxide)s, as well as poly(alkoxylated) alcohols and amines, and the substances are essentially free of any ethylenically unsaturated groups.

The present invention provides a two-component printable conductive composition comprising, as separate components, a metallic component comprising a high melting point (HMP) metal or metal alloy powder having a mean particle size below about 15 m; and a fluxing component comprising an organic acid and an organic solvent. The organic acid is characterized by having at least two carboxylic groups and a first logarithmic acid dissociation constant (p K.sub.a1) of at most about 4. These two components are manufactured and stored separately and are mixed together shortly before the combined conductive composition is used for printing. Further provided is a kit comprising the two-component composition, wherein the metallic component and the fluxing component are disposed in separate containers. The present 10 invention further provides a method for deposition and patterning of the two-component composition, comprising: mixing the metallic component with the fluxing component; and applying the obtained mixture to an insulating substrate.
