## Abstract

A fire extinguishing material forming composition contains: a fire extinguishing agent including at least one of a hygroscopic organic salt and an inorganic salt; and a binder including at least one of a polyvinyl acetal resin and a polyvinyl alcohol resin.

## Claims

### Claim 1

A fire extinguishing material forming composition, comprising:
a fire extinguishing agent including at least one of a hygroscopic organic salt and an inorganic salt; and
a binder including at least one of a polyvinyl acetal resin and a polyvinyl alcohol resin.

### Claim 2 (depends on 1)

The fire extinguishing material forming composition of claim 1, wherein
the composition contains the fire extinguishing agent in an amount of 70 to 97% by mass relative to a total amount of the fire extinguishing agent and the resin.

### Claim 3 (depends on 1)

The fire extinguishing material forming composition of claim 1, wherein
the salt is a potassium salt.

### Claim 4 (depends on 1)

The fire extinguishing material forming composition of claim 1, wherein
the resin has a weight average molecular weight Mw of 10,000 to 150,000.

### Claim 5 (depends on 1)

The fire extinguishing material forming composition of claim 1, wherein
the resin has a glass transition temperature Tg of 55 to 110° C.

### Claim 6 (depends on 1)

The fire extinguishing material forming composition of claim 1, further comprising:
a liquid medium.

### Claim 7 (depends on 1)

A fire extinguishing material formed from the fire extinguishing material forming composition of claim 1.

### Claim 8 (depends on 1)

A method for producing a fire extinguishing member including an adherend having an uneven surface to be treated, and a fire extinguishing agent containing layer provided on the surface to be treated, the fire extinguishing agent containing layer including a binder and a fire extinguishing agent, the method comprising steps of:
(A) preparing the adherend having the uneven surface to be treated; and
(B) forming the fire extinguishing agent containing layer on the surface to be treated,
wherein the fire extinguishing agent containing layer comprises the fire extinguishing material forming composition of claim 1, and
in step (B), the fire extinguishing agent containing layer is formed by wet coating.

### Claim 9

A method for producing a fire extinguishing member including an adherend having an uneven surface to be treated, a fire extinguishing agent containing layer provided on the surface to be treated, and a protective layer provided on a surface of the fire extinguishing agent containing layer, the fire extinguishing agent containing layer including a binder and a fire extinguishing agent, the method comprising:
(A) preparing the adherend having the uneven surface to be treated;
(B) forming the fire extinguishing agent containing layer on the surface to be treated; and
(C) forming the protective layer on the fire extinguishing agent containing layer,
wherein in step (C), the protective layer is formed by wet coating.

### Claim 10 (depends on 1, 9)

The method of claim 9, wherein
the fire extinguishing agent containing layer comprises the fire extinguishing material forming composition of claim 1.

### Claim 11 (depends on 9)
