PROBLEM TO BE SOLVED: To obtain the subject composition exhibiting high moistureproofing performance comparable to polyethylene laminated paper, good in disaggregativeness between the resin layer and paper when recycled and in slip resistance, and free from wax's falling off, comprising paraffin wax and respectively specific other components. SOLUTION: This composition for moistureproofing use comprises (A) pref. 3-95 pts.wt. of paraffin wax (pref. 50-70 deg.C in melting point) and (B) pref. 50-97wt.% of an esterified product from maleinated or fumarated rosin and a polyhydric alcohol (pref. 100-150 deg.C in softening point and <=50 in acid value) and a hydrogenated product therefrom (pref. >=70 deg.C in softening point and <=50 in acid value) and/or (C) a terpenephenol (pref. 100-150 deg.C in softening point and 550-1,100 in number-average molecular weight, pref. a reaction product fromβ-pinene and phenolic resin) and a hydrogenated product from petroleum resin (pref. >=70 deg.C in softening point).
