Adhesive composition

Abstract

Provided is an adhesive composition that includes a first liquid containing gelatin having an amino group; and a second liquid containing a crosslinking agent having at least two functional groups capable of crosslinking reaction with the amino group in one molecule and a polyethylene glycol skeleton, in which a pH of the first liquid at 25° C. is from 6.5 to 9.0, a storage modulus of the first liquid at 25° C. is 1 Pa or less, an amino group concentration of the first liquid is from 4.0 mM to 40.0 mM, a functional group concentration in terms of the functional group contained in the crosslinking agent in the second liquid is from 2.0 mM to 65.0 mM, and a weight average molecular weight of the crosslinking agent is 10000 or more.

Dependencies are inferred from the claim text.
