We describe the calculation of all planar master integrals that are neededfor the computation of NNLO QCD corrections to the production of two off-shellvector bosons in hadron collisions. The most complicated representatives ofintegrals in this class are the two-loop four-point functions where twoexternal lines are on the light-cone and two other external lines havedifferent invariant masses. We compute these and other relevant integralsanalytically using differential equations in external kinematic variables andexpress our results in terms of Goncharov polylogarithms. The case of two equaloff-shellnesses, recently considered in Ref. [1], appears as a particular caseof our general solution.
