PROBLEM TO BE SOLVED: To provide a porous rubber print body capable of reducing a production cost, and capable of absorbing ink to rubber by natural impregnation without reducing rubber hardness and tensile strength without using a vacuum impregnation method for forcibly absorbing ink to rubber.SOLUTION: Rubber, a water-soluble compound, a vulcanizer, and a filler are mixed for forming a master batch. Then, the master batch is vulcanized and then the water-soluble compound is removed for obtaining the porous rubber print body. With respect to 100 pts.wt. of rubber, 0.5-5 pts.wt. of a silicone surfactant is added and mixed. |
