    Abstract: Compounds with isocyanate groups and masked groups reactive in relation to isocyanates, of the formula (I), in which R , R , R , X and Y have the following meaning: R , R are hydrogen, C1- to C10-alkyl, C6- to C10-aryl, C7- to C10-aralkyl or R and R form together C3- to C10-alkane diyl; X, Y are -O-, -S-, (a), in which R is hydrogen, a C1- to C20-alkyl group which is optionally interrupted by oxygen atoms in the ether function, a C6 to C10-aryl group or a C7- to C10-aralkyl group; R is a C1- to C10-alkane diyl group which forms a 4 to 7-membered ring along with the unit -X-CR R -Y-, in which either in the unit R one of the hydrogen atoms or in the unit (b), the radical R is replaced by an allophanate group (R ), in which R is a divalent, aliphatic, alicyclic, araliphatic or aromatic C2- to C20-hydrocarbon unit, and R is a simple bond or a divalent, aliphatic, alicyclic, araliphatic or aromatic C1- to C20-hydrocarbon unit or a mono or poly- (C2- to C4-alkylene oxide) unit, and R is a carbamoyl (c) radical or a biuret group (R ), in which one of the radicals R is hydrogen and the other radical has the same meaning as R , or a biuret group (R ) in which one of the radicals R has the same meaning as R and the other has the same meaning as R , or a thioallophanate group (R ).

    Abstract: The invention relates to diisocyanates of formula (I) in which the radicals have the following meanings: R , R : both radicals are a radical of formula (II) -CH2-CH2-CH2-CH2-CH2-CH2- (diisocyanates Ia); one radical is a radical of formula (II) and the other radical is a radical of formula (III) (diisocyanates Ib); both radicals are a radical of formula (III) (diisocyanates Ic); R is a 5 or 6 linked cycloalkyl radical in which up to 3 hydrogen atoms can be substituted by C1- to C4-alkyl radicals and one or two methylene units can be substituted by an oxygen atom and/or by a tertiary nitrogen atom which additionally carries a C1- to C4-alkyl radical. R can also be a C1- to C4-alkyl radical in which a hydrogen atom is substituted by a 5 or 6 linked cycloalkyl radical in which up to 3 hydrogen atoms can be substituted by C1- to C4-alkyl radicals and one or two methylene units can be substituted by an oxygen atom and/or by a tertiary nitrogen atom, said atom additionally carrying a C1- to C4-alkyl radical, and R is a pyrrolidone radical or a morpholine radical, whereby, with regard to both last-named radicals, the N-atom is bonded on the alkyl radical.
