摘要： The invention provides an alkali-soluble adhesive agent characterized by comprising an alkali-soluble resin that is a reaction product (C) obtained by allowing a polycarboxylic acid and/or a polycarboxylic anhydride having two or more carboxyl groups to react with a reaction product of a compound (A) having at least one epoxy group with a monocarboxylic acid compound (B). Preferably, the alkali-soluble resin is used in combination with a ketone organic solvent, optionally with at least one member selected from the group consisting of a melt viscosity reducing agent, a surface active agent and a plasticizer. The alkali-soluble adhesive agent can be removed by an alkali aqueous solution without recourse to any organic solvent, and is of an environmental protection-conscious type with improvements in adhesion, adhesion strength, coatability, surface smoothness, softening point controllability, melt viscosity controllability and spread controllability.
