Abstract

Process for transferring a surface treatment formulation (210) onto a base paper is described. In one embodiment, the process comprises applying at least one layer of the surface treatment formulation (210) on a non-absorbent film (204) to form a treated substrate (218). The process further comprises transferring the surface treatment formulation (210) from the treated substrate (218) to the base paper (220), to make a treated base paper (226). Surface energy of the surface treatment formulation (210) is less than surface energy of the non-absorbent film (204) and surface energy of the base paper (220).
