Abstract:
The object of the invention is to provide a shoe press belt which has an excellent strength while the variation in strength among its parts being suppressed, and to provide a method for producing such a shoe press belt.
Provided is a shoe press belt for use in a papermaking machine comprising at least one resin layer, wherein the resin layer comprises a polyurethane resin formed by curing an urethane prepolymer having an isocyanate group with a curing agent having an active hydrogen group, wherein the curing agent comprises one or more polycarbonate diol(s) expressed by the following formulae (1) and (2).
HO-Am-Bn—R1OH (1)
