A process for producing an acrylic adhesive sheet, comprising cross-linking an acrylic adhesive agent composition that comprises an acrylic copolymer produced by polymerizing the monomer components comprising the components (a) to (b) mentioned below and an isocyanate cross-linking agent and contains substantially no cross-linking catalyst, thereby forming an acrylic adhesive layer:(a) 80 to 99.9 wt% of a monomer (m1) represented by formula CH2=C(R1)COOR2 (wherein R1 represents a hydrogen atom or a methyl group; and R2 represents an alkyl group having 1 to 20 carbon atoms); and (b) 0.1 to 20 wt% of a monomer (m2) represented by formula CH2=C(R3)CONHR4 (wherein R3 represents a hydrogen atom or a methyl group; and R4 represents a hydroxyalkyl group having 1 to 4 carbon atoms).
