Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 288 words
A triazine compound of the formula ##STR10## in which p is 1, R 2 represents hydrogen, a C 1 - to C 6 -alkyl group or a group of the formula ##STR11## in which R 3 is hydrogen or C 1 - to C 18 -alkyl, R 4 and R 5 are either identical and are hydrogen or a C 1 - to C 5 -alkyl group, in which case R 6 is a methyl group, or R 4 is hydrogen or C 1 - to C 5 -alkyl, and R 5 and R 6 , together with the carbon atoms to which they are bonded, represent a C 5 - or C 6 -cycloalkyl ring or a group of the formula ##STR12## X is a group of the formula ##STR13## in which R 3 , R 4 , R 5 and R 6 have the meaning already given, R 7 represents an alkylene group which has 2 to 4 C atoms and can be substituted by a methyl group and Y represents a group of the formula --OR 8 or --N(R 9 ) 2 , in which R 8 =C 1 - to C 18 -alkyl and R 9 =methyl or ethyl, with the proviso that --R 7 --Y is other than --CH 2 CH 2 --OH, and, R 1 is an alkylene group of the formula --(CH 2 ) r --, in which, in the case where m=0, the indices r and n can be identical or different and represent an integer from 2 to 6, but in the case where m=1, 2 or 3, the index 1 represents 2 or 3 and the indices r and n are identical and likewise represent 2 or 3.
Claim 2
Dependent Claim 288 words
A triazine compound of the formula ##STR10## in which p is 1, R 2 represents hydrogen, a C 1 - to C 6 -alkyl group or a group of the formula ##STR11## in which R 3 is hydrogen or C 1 - to C 18 -alkyl, R 4 and R 5 are either identical and are hydrogen or a C 1 - to C 5 -alkyl group, in which case R 6 is a methyl group, or R 4 is hydrogen or C 1 - to C 5 -alkyl, and R 5 and R 6 , together with the carbon atoms to which they are bonded, represent a C 5 - or C 6 -cycloalkyl ring or a group of the formula ##STR12## X is a group of the formula ##STR13## in which R 3 , R 4 , R 5 and R 6 have the meaning already given, R 7 represents an alkylene group which has 2 to 4 C atoms and can be substituted by a methyl group and Y represents a group of the formula --OR 8 or --N(R 9 ) 2 , in which R 8 =C 1 - to C 18 -alkyl and R 9 =methyl or ethyl, with the proviso that --R 7 --Y is other than --CH 2 CH 2 --OH, and, R 1 is an alkylene group of the formula --(CH 2 ) r --, in which, in the case where m=0, the indices r and n can be identical or different and represent an integer from 2 to 6, but in the case where m=1, 2 or 3, the index 1 represents 2 or 3 and the indices r and n are identical and likewise represent 2 or 3.
