PROBLEM TO BE SOLVED: To provide a puncture sealing material for tire capable of decreasing the amount to be injected into a tire, generating low noise in driving and keeping the driving stability and provide a puncture sealing material for tire exhibiting excellent sealing performance even in rainy or cold environment. SOLUTION: The puncture sealing material for tire is composed of a first liquid agent containing a cationic resin and a second liquid agent containing an anionic resin., especially a combination of a cationic urethane emulsion and an anionic chloroprene emulsion. The puncture sealing material for tire can decrease the amount to be injected into the tire, generates low noise in driving and keeps driving stability. Especially when the first and the second agents have hydrogen ion exponents falling within a specific range, the puncture sealing material for tire exhibits excellent sealing performance in rainy or cold environment.
