(A) 40 to 65% by weight of an ethylene copolymer containing 5% by weight or more of a highly crystalline ethylene-vinyl acetate copolymer (B) Tackifying resin 20 to 45% by weight (C) 5-30% by weight of wax Having a 50% modulus strength in a tensile test at 23 ° C. and 65% RH of 20 to 40 kgf / cm 2 and a melt viscosity at 180 ° C. of 1,000 to 10,000 mPa · s. A hot melt adhesive for bookbinding. According to the present invention, since the solidification speed at the time of use is excellent, the workability is excellent, and since it is not shredded in the fibrillation step by a pulper when recycled as used paper, it can be easily filtered with a filter. It is possible to provide a hot melt adhesive that is optimal for bookbinding and calendar production without adversely affecting the papermaking process and the quality of paper.
