The composition comprises at least one n,5-dihydroxy-1,2,3,4-tetrahydro-naphthalene having the general formula ##STR1## wherein n represents a number from 1,2,3, or 4, and which n,5-dihydroxy-1,2,3,4-tetrahydronaphthalene can be present as such or as a salt of an organic or inorganic base and which n,5-dihydroxy-1,2,3,4-tetrahydro-naphthalene serves as a coupling compound; and at least one developer employed in hair dyeing. Intense and red tinge free blue colorations can be obtained.Type: GrantFiled: January 25, 1980Date of Patent: March 23, 1982Assignee: Wella AktiengesellschaftInventors: Eugen Konrad, Herbert Mager

Patent number: 4297098Abstract: Living human hair is progressively colored to the desired light brown shade by repeated applications of a preparation containing a low concentration of a mixture of oxidative dye components, namely, 2 to 3 components selected from p-phenylenediamine (or p-toluenediamine), pyrogallol, and m-aminophenol. To obtain a gradual, true color development, it is important to employ the dye components in certain relative proportions. In the use of the preparation, no oxidizing agent is added, and the color development reaction is obtained by contact of the dye mixture with atmospheric oxygen. The preparation is preferably in the form of an aqueous gel also containing hair grooming or conditioning agents.Type: GrantFiled: August 26, 1976Date of Patent: October 27, 1981Assignee: Alberto-Culver CompanyInventors: George F. Dasher, Thomas J. Schamper
