    摘要: In a method for determining weighting factors for the color calculation of a color value of texels for a footprint covering a plurality of texels in a texel grid, in a graphic system, form information of the footprint is determined at first. Afterwards, the edges of the footprint are determined and the edges determined in this way are approximated by a staircase function. The texels of the texel grid contacted by the staircase function are determined and a weighting factor is determined for each texel containing a portion of the staircase function, depending on the subarea of the respective texel covered by the footprint.

    摘要: The present invention relates to a process for the production of oligomeric polyisocyanates by the dimerization or trimerization of a portion of the isocyanate groups in organic polyisocyanates in the presence of tertiary phosphines or in the presence of a peralkylated phosphorus acid triamides as catalyst, followed by termination of the dimerization and/or trimerization reaction at the required degree of oligomerization by the addition of a catalyst poison, characterized in that a sulfonyl isocyanate is used as the catalyst poison.The present invention also relates to the use of the oligomeric polyisocyanates obtained by this process, optionally in admixture with unreacted starting polyisocyanate or optionally blocked by blocking agents for isocyanate groups, as the polyisocyanate component in the production of polyurethane plastics.
