Iminoxytriazines as radical generators

Iminoxytriazine compounds of the formula I wherein n is 1 or 2; R1 and R2 independently of each other are hydrogen, NH2, NHR5, NR5R6, COR5, COOR5, CONH2, CONHR5, CONR5R6, CN, SR5, OR5, C1-C18alkyl, C3-C12cycloalkyl, C6-C14aryl or C2-C14heteroaryl, wherein said C3-C12cycloalkyl, C6-C14aryl or C2-C14heteroaryl is unsubstituted or substituted by one or more radicals selected from the group consisting of C1-C12alkyl, C3-C12-cycloalkyl, phenyl, halogen and C1-C12 alkoxy, or R1 and R2 together with the C atom to which they are linked form a 4 to 12 membered carbocyclic or heterocyclic saturated or unsaturated ring which is unsubstituted or substituted by one or more radicals selected from the group consisting of C1-C12alkyl, C3-C12-cycloalkyl, phenyl, halogen and C1-C12 alkoxy; R3 is F, Cl, OH, OR5, SH, SR5, NH2, NHR5, NR5R6 or R1R2C N-O-; wherein R1 and R2 in all groups R1R2C N-O- in the compound of the formula I are identical or different; if n is 1, R4 is F, Cl, OH, OR5, SH, SR5, NH2, NHR5, NR5R6 or R1R2C N-O-; wherein R1 and R2 in all groups R1R2C N-O- in the compound of the formula I are identical or different; if n is 2, R4 is a difunctional group derived from a diol, diamine, aminoalcohol or mercaptoalcohol; R5 and R6 independently of each other are C1-C18alkyl, C3-C12cycloalkyl, C6-C14aryl or C2-C14heteroaryl; are suitable as radical generating agents.
