A mass transfer imaging element comprising a substrate having a surface colourant layer containing a pigment to be imagewise transferred, wherein said colourant layer comprises a fluorocarbon additive in an amount to provide a fluorocarbon additive:pigment weight ratio of at least 1:20.

Transfer imaging elements

A mass transfer imaging element comprising a substrate having a surface colorant layer containing a pigment to be imagewise transferred, wherein said colorant layer comprises a fluorocarbon additive in an amount to provide a fluorocarbon additive:pigment weight ratio of at least 1:20.

An inkjet receptor medium wherein the medium is microporous and has on one major surface an imaging layer comprising a coating of a mixture of amorphous precipitated and fumed silicas and binder. Dot diameter of pigmented inkjet inks can be controlled using the receptor medium, which is advantageous for inks delivered in small picoliter volumes. Methods of making and using the medium are also disclosed.

Coated microporous inkjet receptive media and method for controlling dot

This invention relates to an ink jet printing sheet having a particle filled ink receptor layer and a particle filled protective penetrant layer. The particles from both the ink receptor layer and protective penetrant layer cause protrusions from the protective penetrant layer.

Ink jet printing sheet

A colour sheet suitable for use in peel-apart colour imaging comprising a substrate bearing a layer of pigmented photopolymerizable material overcoated with a hydrophilic barrier layer and an outer layer of an adhesive.
