Labels are printed from a liquid ink having mineral oil by printing on a sheet having a Teslin brand synthetic paper lamination followed by an organic adhesive lamination in contact with the synthetic paper, followed by a supporting lamination. The synthetic paper can be as thin as 8 ml and no barrier layer is needed to protect the adhesive from the mineral oil.

Label printing using microporous label surface

Trimers of C.sub.9 to C.sub.11 alpha olefins are useful as carrier fluid in liquid toner for electrophotography. Their use practically eliminates air pollution, oil slicks when liquid toned prints are placed on a surface and a halo effect.

Carrier fluid for liquid electrophotographic toner

A liquid toner for electrostatic imaging having 65-90 percent by weight of solids of terpolymer of about in the weight ratio of about 60/33/7 of styrene, n-butyl acrylate and methacrylic acid, respectively; 10-30 percent by weight of solid of pigment, an ionic or zwitterionic charge director, 1-5 percent by weight aluminum tristearate, and the remainder mineral oil as a vehicle.
