<p>A two-component curable solventless adhesive with which a laminated composite film composed of a laminate of barrier layer and plastic film even after sterilization at high temperature retains excellent appearance and bonding strength over a prolonged period of time and with which at the manufacturing of the laminated composite film, the reaction between a base resin and a curing agent is appropriately regulated to thereby ensure desirable workability. There is provided a two-component curable solventless adhesive comprising a base resin and a curing agent, wherein the base resin contains a polyol having secondary or tertiary terminal hydroxyls in a proportion of 30% or more based on all the terminal hydroxyls and containing an acid group, while the curing agent contains an isocyanate-terminated urethane prepolymer from a raw polyisocyanate containing at least an aromatic-aliphatic polyisocyanate and/or a substance resulting from modification thereof, in which the content of low-molecular-weight polyisocyanates of 190 or less molecular weight is 3 wt.% or below.</p>
