    摘要： The present invention relates to inner coatings of metal food containers and packaging and to a process for their production. The coatings are applied to the inside of at least a portion of the surface area of containers that are in direct contact with foods or other consumable products and subsequently cured. The coatings include a) at least one polyisocyanate containing an average of at least two NCO groups per molecule, at least 95% of the NCO groups being blocked with a blocking agent, and b) at least one polyhydroxyl compound containing an average of at least two hydroxyl groups per molecule that react with NCO groups.

    摘要： Disclosed herein are bridged perinones/quinophthalones of the general formula (I) or tautomeric forms thereof where X1, X2, Ar1 Ar2 and B are as described herein and are particularly characterized in that the bridging B is a radical of the formula —T1—W—T2—, where T1 and T2 are independently O or S and W is alkylene, especially C1-C6-alkylene, C6-C10-arylene, especially phenylene or cycloalkylene, which are each optionally substituted or is the radical of the formula (a) where the phenyl rings are optionally substituted and A is a radical of the formula O, S, SO, SO2 or CO, optionally substituted alkylene, or optionally substituted cycloalkylene, said alkylene or cycloalkylene being attached to the adjacent phenyl rings itself or else via its substitutents, or W is a radical of the formulae where s and t are independently from 1 to 6, the ends of the radical B each being attached to an aromatic carbon atom of the two radicals Ar1 and Ar2.

    摘要： Blocked polyisocyanates and one-component stoving systems containing these blocked polyisocyanates, and the preparation thereof and their use for the preparation of lacquers, paints, adhesives and elastomers. The blocked polyisocyanates are derived from polyisocyanates reacted with secondary amines and cationic, anionic and/or nonionic hydrophilizing agents such that they are incorporated into the polyisocyanate at a ratio of from 20:1 to 1:1, wherein the blocking agents correspond to the formula R1–R4 can be identical or different and independently of one another denote hydrogen, C1–C6-alkyl or C3–C6-cycloalkyl, R5 denotes C1–C10-alkyl, C3–C10-cycloalkyl, and B represents  wherein R6–R8 can be identical or different and independently of one another denote C1–C6-alkyl and/or C1–C6-cycloalkyl, R9 denotes hydrogen or C3–C6-alkyl or C3–C6-cycloalkyl.
