A sulfonium borate complex that is capable of reducing the amount of fluorine ions generated during thermal cationic polymerization, and is capable of providing a thermal cationic polymerizable adhesive with low-temperature fast curing properties is represented by a structure represented by the formula (1). In the formula (1), Ris an aralkyl group, Ris a lower alkyl group, and Ris a lower alkoxycarbonyl group. X is a halogen atom, and n is an integer of from 1 to 3.

A thermosetting adhesive is configured to include a photoradical generator which generates radicals from irradiation of active energy rays in a thermosetting insulating adhesive component. In a repair method when this thermosetting adhesive is used, a cured matter of the thermosetting adhesive is made soluble or swellable in a predetermined solvent by irradiating the cured matter with active energy rays from the substrate side or the electronic component side prior to separating the electronic component from the substrate, and the cured matter is removed using such solvent. Alternatively, the cured matter of the thermosetting adhesive is made soluble or swellable in a predetermined solvent by irradiating the cured matter with active energy rays after the electronic component has been separated from the substrate, and the cured matter is removed using such solvent.

Thermosetting adhesive

Provided is an anisotropic conductive film, containing: an insulating layer formed of an insulating resin composition; and a conductive particle-contained layer containing a photo and thermal curing resin composition and conductive particles, the conductive particles being aligned into a monolayer in a portion adjacent to an interface with the insulating layer, in which the conductive particle-contained layer has a degree of cure which is gradually lowered in a thickness direction of the conductive particle-contained layer, from the side where the conductive particles are present to the side where the conductive particles are not present.

A liquid absorbing sheet has a liquid-absorbing resin layer that can effectively absorb the nonaqueous electrolyte solution used in nonaqueous electrolyte secondary cells that make nonaqueous electrolyte battery packs (in particular, lithium ion-based nonaqueous secondary battery packs). The liquid-absorbing resin layer is obtained by irradiating a particular monomer composition with UV rays or other energy rays to polymerize the monomer composition. The monomer composition contains a monofunctional monomer component (A) having a polyethylene glycol acrylate monomer and an amide bond-containing acrylic monomer; and a polyfunctional monomer component (B).

Liquid absorbing sheet and nonaqueous electrolyte battery pack

In a battery pack including a battery case containing therein a battery cell, a wiring circuit board, and a liquid-absorbing element capable of absorbing the electrolyte leaking out from the battery cell, the liquid-absorbing element is inserted with looseness allowing for expansion in a gap formed by a retaining element on the inner wall surface of the battery case or retaining element on the wiring circuit board. Alternatively, a liquid-absorbing element consisting of a non-absorbent porous retaining element partially holding a liquid absorbent is used and the porous retaining element is fixed to the inner wall surface of the battery case or the wiring circuit board at an absorbent-free zone.

Battery packs

A liquid absorbing sheet includes a liquid absorbing resin layer that can effectively absorb nonaqueous electrolyte solutions used in nonaqueous electrolyte secondary cells that make nonaqueous electrolyte battery packs (in particular, lithium ion-based nonaqueous secondary battery packs). The liquid absorbing resin layer is obtained by irradiating UV-rays onto a monomer composition to polymerize the monomer composition, the monomer composition containing:
