摘要:
Provided is a photocurable and thermosetting adhesive for inkjet which can increase the thickness accuracy of an adhesive layer formed by curing an adhesive and can further cause the adhesive layer to hardly generate voids. A photocurable and thermosetting adhesive for inkjet according to the present invention contains a photocurable compound, a thermosetting compound, a photopolymerization initiator, and a thermal curing agent, wherein the elastic modulus at 25°C of a B-staged adhesive is at least 5.0 × 10 2 Pa and at most 8.0 0 × 10 4 Pa when the B-staged adhesive is obtained by irradiating the adhesive with light of a cumulative light quantity of 1000 mJ/cm 2 so that illumination at a wavelength of 365 nm is 100 mW/cm 2 .
