We proposed a polymer composed of (b) rosin and (c) an ethylene polymer (Japanese Patent Publication No. 34547/1989). In the above proposal, in order to obtain good alkali dispersibility, the composition of each resin component in the composition is such that the total blending ratio of wax and rosin accounts for 70% by weight or more, while the amount of the ethylene-based polymer used is It is specified that the amount should be 29% by weight or less. Therefore, it is difficult to obtain a composition having high strength and high cohesiveness, which has a drawback that the field of use is limited.
In the previous proposal developed for such a purpose, even if the proportion of the ethylene polymer used is simply increased in order to improve the strength, the alkali dispersibility deteriorates, and especially for a high-concentration alkaline aqueous solution. However, it was difficult to obtain a good dispersion.

Parts by weight. When the amount of the component (A) used is less than the above range, it is difficult to obtain a composition having excellent cohesiveness and high strength. If the amount used is too large, the coatability will be reduced, although it will depend on the melt flow rate of the component (A), but it should be kept to 60 parts by weight or less. The component (B) is an important component that imparts alkali dispersibility and adhesiveness to various substrates to the composition, and also acts as a compatibilizing agent for the components (A) and (C). Since the composition becomes brittle when used, the above range of use should be adjusted. The component (C) is an important component that improves the coatability of the composition and keeps it non-adhesive. However, if used in too large an amount, the composition tends to become brittle, so it is used in the ratio described above. It
