Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
121 words
A dye compound base for dyeing live human hair, said compound having the formula ##STR15##wherein Z 1 is selected from the group consisting of --NH 2 , --NHCH 3 and --OH, Z 2 is selected from the group consisting of --NH 2 and --NHCH 3 , R 1 and R 2 each independently are selected from the group consisting of hydrogen and methyl, R is selected from the group consisting of hydrogen, hydroxyethyl and diethylaminoethyl with R being diethylaminoethyl when Z 1 and Z 2 are both --NH 2 and Y is --(CH 2 ) n-- wherein n is 0 or 2; and the salt of said compound with an acid selected from the group consisting of hydrochloric and hydrobromic acids.
Claim 2
Dependent Claim
121 words
A dye compound base for dyeing live human hair, said compound having the formula ##STR15##wherein Z 1 is selected from the group consisting of --NH 2 , --NHCH 3 and --OH, Z 2 is selected from the group consisting of --NH 2 and --NHCH 3 , R 1 and R 2 each independently are selected from the group consisting of hydrogen and methyl, R is selected from the group consisting of hydrogen, hydroxyethyl and diethylaminoethyl with R being diethylaminoethyl when Z 1 and Z 2 are both --NH 2 and Y is --(CH 2 ) n-- wherein n is 0 or 2; and the salt of said compound with an acid selected from the group consisting of hydrochloric and hydrobromic acids.
Claim 3
Dependent Claim
135 words
