N2 - The singlet structure function of a deep inelastic process, D(x, q2, is studied in the double log approximation of perturbative QCD at small x and large q2. It is shown, how the increase of D at small x is screened by multiladder diagrams, so that the unitarity is not violated. The equation that sums such diagrams is written and solved, the screening effects being reduced to a specific boundary condition for the ladder equation.
