Abstract

The inside surface of an ink jet capillary is coated with a thin film of an oil absorbent release coating, such as a sili-cone elastomer, in conjunction with an oil based ink which can wet the coated wall of the capillary to prevent adhesion of resin coated ink pigment particles to the wall and also to produce plug flow. The desired ink for silicone elastomer coatings comprises a mineral oil or silicone oil capable of diffusing in the silicone. Ink repellancy is not desired for this use, nor is the establishment of a non-wetted ring con-forming to the coated areas. In addition, the ink should be free of si1icone-compatible polymers which might diffuse into the release coating and cause clogging. Normal resinated or flushed ink pigments are recommended for such a capillary.
