Disclosed herein is a tackifying composition for rubber comprising an alkali lignin coprecipitated with a saponified tall oil pitch from an alkaline solution of the lignin and the pitch, the amount of saponified tall oil pitch being from 25% to 75% of the weight of said lignin. When the lignin-saponified pitch composite is added to a raw rubber stock in an amount of from 1 part to 50 parts per 100 parts of raw rubber stock the tack is improved.
