摘要：
This invention provides a sizing composition for cellulosic fiber sheets comprising water and finely divided solid particles dispersed in the water, said particles being a uniform mixture of about 40 to about 96% by weight of a ketene dimer and about 4 to about 60% by weight of a noncrystalline hydrocarbon resin; and a process for preparing the sizing composition.The sizing composition of this invention is excellent both in sizing effects and in stabilities.
