## Abstract

An adhesive set includes a main agent containing a decomplexing agent and an initiator containing an organoborane complex. At least one of the main agent and the initiator further contains a compound having a radically polymerizable group. At least one of the main agent and the initiator further contains a polymerization control agent. At least one of the main agent and the initiator further contains a peroxide.

## Claims

### Claim 1

An adhesive set comprising:
a main agent comprising a decomplexing agent; and
an initiator comprising an organoborane complex, wherein
at least one of the main agent and the initiator further comprises a compound having a radically polymerizable group,
at least one of the main agent and the initiator further comprises a polymerization control agent,
at least one of the main agent and the initiator further comprises a peroxide, and
the polymerization control agent comprises at least one selected from the group consisting of a halogenated metal salt and a compound having a thiocarbonylthio structure.

### Claim 2 (depends on 1)

An adhesive body comprising:
a first adherend;
a second adherend; and
an adhesive layer interposed between the first adherend and the second adherend, the adhesive layer bonding the first adherend and the second adherend to each other, wherein
the adhesive layer comprises a cured product of an adhesive composition comprising the main agent and the initiator of the adhesive set according to claim 1.

### Claim 3 (depends on 2)

A method for manufacturing the adhesive body according to claim 2, the method comprising:
pasting the first adherend and the second adherend together with the adhesive composition comprising the main agent and the initiator.

### Claim 4 (depends on 1)

The adhesive set according to claim 1, wherein the initiator further comprises a filler, a cross-linking agent, and a plasticizer.

### Claim 5 (depends on 1)

The adhesive set according to claim 1, wherein the main agent comprises the compound having the radically polymerizable group, the polymerization control agent, and the peroxide.

### Claim 6 (depends on 5)

The adhesive set according to claim 5, wherein the main agent further comprises a filler.

### Claim 7 (depends on 1)

The adhesive set according to claim 1, wherein the polymerization control agent comprises the halogenated metal salt.

### Claim 8

An adhesive composition consisting essentially of:
a decomplexing agent;
an organoborane complex;
a compound having a radically polymerizable group;
a polymerization control agent;
a peroxide;
a filler;
a cross-linking agent; and
a plasticizer,
wherein the polymerization control agent comprises at least one selected from the group consisting of a halogenated metal salt and a compound having a thiocarbonylthio structure.
