         3 . (canceled) 
     
     
         4 . The coagulant according to  claim 1 , further comprising
 at least one deliquescent inorganic salt selected from the group consisting of sodium chloride, potassium chloride and magnesium chloride.   
     
     
         5 . The coagulant according to  claim 1 , wherein the tire puncture repair liquid comprises at least one selected from the group consisting of a natural rubber latex and a synthetic resin emulsion. 
     
     
         6 . The coagulant according to  claim 5 , wherein the tire puncture repair liquid further comprises an anti-freezing agent. 
     
     
         7 . The coagulant according to  claim 1 , wherein a used amount with respect to the tire puncture repair liquid is 5 to 150 parts by mass per 100 parts by mass of the tire puncture repair liquid. 
     
     
         8 . A tire puncture repair kit comprising: the coagulant according to  claim 1 ; and a tire puncture repair liquid. 
     
     
         9 . The coagulant according to  claim 2 , further comprising
 at least one deliquescent inorganic salt selected from the group consisting of sodium chloride, potassium chloride and magnesium chloride.   
     
     
         10 . The coagulant according to  claim 2 , wherein the tire puncture repair liquid comprises at least one selected from the group consisting of a natural rubber latex and a synthetic resin emulsion. 
     
     
         11 . The coagulant according to  claim 4 , wherein the tire puncture repair liquid comprises at least one selected from the group consisting of a natural rubber latex and a synthetic resin emulsion. 
     
     
         12 . The coagulant according to  claim 2 , wherein a used amount with respect to the tire puncture repair liquid is 5 to 150 parts by mass per 100 parts by mass of the tire puncture repair liquid. 
     
     
         13 . The coagulant according to  claim 4 , wherein a used amount with respect to the tire puncture repair liquid is 5 to 150 parts by mass per 100 parts by mass of the tire puncture repair liquid. 
     
     
         14 . The coagulant according to  claim 5 , wherein a used amount with respect to the tire puncture repair liquid is 5 to 150 parts by mass per 100 parts by mass of the tire puncture repair liquid. 
     
     
         15 . The coagulant according to  claim 6 , wherein a used amount with respect to the tire puncture repair liquid is 5 to 150 parts by mass per 100 parts by mass of the tire puncture repair liquid. 
     
     
         16 . A tire puncture repair kit comprising: the coagulant according to  claim 2 ; and a tire puncture repair liquid. 
     
     
         17 . A tire puncture repair kit comprising: the coagulant according to  claim 4 ; and a tire puncture repair liquid. 
     
     
         18 . A tire puncture repair kit comprising: the coagulant according to  claim 5 ; and a tire puncture repair liquid. 
     
     
         19 . A tire puncture repair kit comprising: the coagulant according to  claim 6 ; and a tire puncture repair liquid. 
     
     
         20 . A tire puncture repair kit comprising: the coagulant according to  claim 7 ; and a tire puncture repair liquid.
