• in which K is a group of the formulae
• R1, R2, R3 and R4, in each case individually, are hydrogen, hydroxyl, C1- to C24-alkyl, C2- to C24-alkenyl, C1-C4-alkoxy-C1-C4-alkyl, phenyl, C1- to C4-alkylphenyl, carboxyl, sulfonyl, cyanomethyl, cyano;
• R5 and R6, in each case independently of one another, are a straight-chain or branched-chain C1- to C24-alkyl, alkenyl or alkyl ether group, and
