摘要： The present invention relates to a process for producing an acrylic pressure-sensitive adhesive sheet, containing forming an acrylic pressure-sensitive adhesive layer by crosslinking an acrylic pressure-sensitive adhesive composition containing: an acrylic copolymer obtained by polymerizing monomer components containing the following (a) and (b); and isocyanate-based crosslinking agent, and containing substantially no crosslinking catalyst: (a) 80 to 99.9 wt % of monomer (m1) represented by CH2═C(R1)COOR2 (R1 represents a hydrogen atom or a methyl group, and R2 represents an alkyl group having a carbon number of 1 to 20); and (b) 0.1 to 20 wt % of monomer (m2) represented by CH2═C(R3)CONHR4 (R3 represents a hydrogen atom or a methyl group, and R4 represents a hydroxyalkyl group having a carbon number of 1 to 4).
