ABSTRACT:
A paper size obtained by the steps of treating with an acid a hydrocarbon distillate boiling within the range of 20.degree.-80.degree. C. and containing at least one C.sub.5 acyclic conjugated diolefin in an amount of 10 to 35 wt. % of the distillate, the distillate being derived from a fraction obtained as a by-product at the time of cracking petroleum, reacting said hydrocarbon distillate with an .alpha.,.beta.-unsaturated carboxylic acid in a specified weight ratio and then saponifying the thus obtained acid-modified hydrocarbon distillate with an alkali thereby to obtain the paper size.
