  • Patent number: 11008488
    Abstract: Provided are an adhesive composition and a film roll whereby blocking can be prevented and excellent temporary pressure bonding properties can be obtained. The adhesive composition of the present invention contains an epoxy resin, a latent curing agent, and an acrylic rubber having a carboxyl group or a glycidyl group, and the acrylic rubber phase-separates from the epoxy resin at a normal temperature and is compatible with the epoxy resin at a predetermined temperature higher than the normal temperature and lower than the curing temperature. Adhesive force is thereby reduced at the normal temperature, blocking can be prevented from occurring and excellent adhesive force can be obtained during temporary pressure bonding.
    Type: Grant
