Abstract
A method of adhesion provides excellent workability by using a curable resin composition whose viscosity has low temperature dependence. The method of adhesion includes a step of heating a curable resin composition and applying a curable resin composition, a step of spreading the curable resin composition, and a step of curing the curable resin composition. The curable resin composition contains specific amounts of an epoxy resin, fine polymer particles that have a core-shell structure including a core layer and a shell layer, and blocked urethane having a latent NCO % of 0.1% to 2.9%.
