PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive that is a pressure-sensitive adhesive for bonding a support film to a glass plate, can maintain sufficient adhesion even exposed to a high-temperature environment when a following ITO sputtering treatment, formation of color filter layer, formation of image display element, etc., are carried out.SOLUTION: A pressure-sensitive adhesive for bonding a support film to a glass plate in a method for obtaining a glass substrate by thinning the glass plate in which the support film is bonded to one surface comprises a condensation-based resin having a structural unit obtained by condensation polymerization of polymerizable monomers containing a monomer (A) having at least two carboxy groups and a monomer (B) having at least two amino groups, where the condensation-based resin satisfies at least one of the following (1) and (2). (1) At least one kind selected from the group consisting of the monomer (A), an anhydride of the monomer (A) and the monomer (B) is liquid at 25°C. (2) The condensation-based resin contains a polyoxyalkanediyl group. |
