Abstract: The invention relates to compositions useful as release agents containing saponified fatty and/or rosin acids, as well as methods of making and using the same.

Abstract: There is disclosed a method for sizing paper by adding to the surface of the paper a sizing composition comprising cellulose reactive and cellulose non-reactive size. The sized paper performs better in ink jet printing than does paper that is the same except that the size composition contains only cellulose reactive size or only cellulose non-reactive size, when the printing is evaluated for at least one property selected from the group consisting of optical density, feathering, wicking, edge roughness and bleed. The sized paper also has higher toner adhesion, a higher coefficient of friction and a lower coefficient of friction bandwidth than does paper that is the same except that the size composition contains only cellulose reactive size. The paper is also capable of performing effectively in tests that measure its convertibility on state-of-the-art converting equipment and its performance on high speed end-use machinery.
