The disclosure relates to a coating composition that can be applied to a substrate, especially a cellulose substrate. A layer of the coating composition applied to the substrate provides an excellent ink receptive layer and can be used as a coating on paper. The disclosure also relates to aqueous compositions and method for applying the layer of the coating composition onto the substrate.

The invention relates to a paper-based printed electronic device comprising one or more sheets of paper that is impregnated with a resin in way to fill the voids (or pores) of porous networks of cellulose fibers and in particular to saturate said porous networks of cellulose fibers, as well as to coat the outer surfaces of the printed electronics with said resin. A fully encapsulated electronic device is obtained which is protected against external environmental and physical damages such as against moisture and oxygen and has acquired sufficient resistance to tearing. The impregnated and encapsulated electronic device can then be successfully integrated into an object in a form of a flat or curved monolithic structure. This may especially be achieved through a lamination process, as said device sustains high pressure, high temperature, does not create bubbles, does not delaminate, and can be fully embedded into an end product.

This invention relates to a paper friction material and a method of manufacturing the same, wherein the paper friction material is configured such that dispersibility and bondability are increased between a filler and a matrix. The paper friction material which is suitable for use in a vehicle, includes a friction base including pulp and a coating layer formed on the friction base using a mixture of latex and a functional material. The OH reactive group of the pulp and the aromatic ring of the latex are hydrogen-bonded so that the friction base and the coating layer are coupled with each other.
