In the field of papermaking and more particularly a method for producing paper impregnated with a molecule of interest, particularly colored paper, and the associated product, i.e. impregnated paper, there is a disclosed a method implementing a supercritical-pressure fluid. Such paper, particularly colored paper, obtained from a formulation of paper pulp or paper including latex, does not bleed when it comes into contact with water.

Method for producing paper impregnated by a supercritical-pressure fluid, and impregnated, particularly coloured paper

The invention relates to a method to embed a label essentially consisting of a paper substrate carrying electronic inks and/or a printed electronic circuit and/or device (thereby achieving a paper-based electronic circuit) directly into a moulded plastic piece (also designated as plastic object), the embedding of the paper-based electronic circuit and the production of the plastic piece being performed in a single operation. The invention thus also relates to a method to manufacture plastic objects embedding such label. The invention also concerns a plastic object encompassing a label essentially consisting of a paper substrate carrying electronic inks and/or a printed electronic circuit and/or device (thereby achieving a paper-based electronic circuit) embedded in the moulded plastic and in particular an object obtained by the method disclosed to prepare a moulded plastic piece.
