Abstract: A synthetic paper having good ink adhesion thereto which comprises:A. a synthetic paper substrate comprising a papery layer which is a stretched resin film which contains fine filler particles dispersed therein and has microvoids dispersed therein and surface ruptures thereon; andB. a layer for improving ink adhesion to the synthetic paper which is provided on at least one surface of the papery layer and comprises, as an essential constituent, an ethyleneimine adduct of a polyaminepolyamide.

Abstract: In a process for production of a synthetic paper comprising a paper-like layer which comprises stretching in at least one direction a sheet comprising a layer of film of a resin loaded with a fine filler so as to whiten said film thereby to obtain a synthetic paper comprising the whitened film as the paper-like layer, the improvement for production of such a synthetic paper improved in dusting trouble, which improvement comprises coating said film to form said paper-like layer upon stretching with an aqueous binder material which can be dry-extensible, drying the binder material, and effecting the step of said stretching.
