The multilayer film may include a polymeric core layer; and one or more printing layers adjacent to the polymeric core layer. The one or more printing layers may include at least 50 wt. % of an ethylene vinyl acetate copolymer having acid and acrylate functional groups. The ethylene vinyl acetate copolymer having acid and acrylate functional groups may include from 0.5 wt. % to 4 wt. % methacrylic or acrylic acid; from 0.5 wt. % to 4 wt. % acrylate, from 7 wt. % to 40 wt. % vinyl acetate; and the balance ethylene, based on the total weight of the ethylene vinyl acetate copolymer having acid and acrylate functional groups.

Printing substrates

The present disclosure relates to a process for printing a substrate. The process comprises applying an analogue primer over a print substrate. A transparent electrophotographic composition comprising a coupling agent is electrophotographically printed on the primer as a coupling layer. An electrophotographic ink composition is then printed on the coupling layer to form an image layer. The coupling layer is disposed between the primer and image layer and in contact with each of the primer and image layer.

PRINTING SHEET
20210072655 · 2021-03-11 ·

A printing sheet is formed of a base material film, a toner fixing layer formed on one principal surface of the base material film, a planarization layer formed on the other principal surface of the base material film, an adhesive layer formed on the surface of the planarization layer, and a peeling film stuck on the surface of the adhesive layer. The base material film has a laminated structure composed of a white foamed PET film layer on the toner fixing layer side and a transparent non-foamed PET film layer on the adhesive layer side, and the strength of the printing sheet is improved by the combined use of the non-foamed PET film. The planarization layer is formed of a colored ink layer, e.g. white ink layer, and increases the bonding area of the adhesive layer with the base material film side, thereby achieving smooth peeling from an adherend.
