Abstract
A process for making a special paper soluble in alkaline aqueous solutions that has an excellent aptitude for graphic printing, which comprises forming a continuous paper using as a raw material for the manufacture of paper a fibrous cellulose ether, which is soluble in a solution aqueous alkaline but not in water, or a mixture of at least 0.2 parts by weight of said cellulose ether and 1 part by weight of the plain papermaking raw material, apply to the resulting continuous paper an alkaline aqueous agent of surface treatment containing a dry film-forming substance, which is soluble in an alkaline aqueous solution but not in water, and thereafter drying such continuous paper before a major reaction occurs between the cellulose ether and the alkali present on continuous paper.
