PURPOSE:A novel two-pack type adhesive having improved storage stability and adhesiveness, obtained by adding a diene elastomer and a specific unsaturated polyester to an acrylic monomer solution containing an organic peroxide and an acrylic monomer solution containing a curing promotor. CONSTITUTION:A diene elastomer (e.g., nitrile rubber, etc.) is added to at least one ofIsolution consisting of an acrylic monomer (e.g., methylmethacrylate, etc.) and an organic peroxide (e.g., t-butyl hydroperoxide, etc.) and II solution consisting of the acrylic monomer and a curing promotor (e.g., vanadyl acetylacetonato, etc.), and an ion-containing unsaturated polyeser[e.g., one shown by the formula (R is H, 1-2C alkyl, etc.; R' is dibasic acid residue; n is 4-20), etc.]having one or more polymerizable or copolymerizable double bonds in the molecule and a remaining carboxyl group which is neutralized is added toIsolution or bothIand II solutions, and, if necessary, a various kinds of additives are added to the solutions, to give the desired two-pack adhesive.
