A new resin composition comprising an emulsion polymerized resin, a surfactant, and a polyacrylic acid-polyacrylamide copolymer; and a method of controlling the deposition of such resin composition on porous, absorbent materials by giving it a pH of from about 7 to about 9, or greater, at which it is stable, and then depositing it on the porous, absorbent sheet materials which have a pH of below 7 and which possess sufficient acidity as to bring the pH of the resin composition deposited thereon to below 7, at which it is unstable, whereupon it immediately coagulates and immediately precipitates on the porous, absorbent sheet materials with a minimum of lateral spread or migration thereon.
