Patent number: 5998621Abstract: This invention relates to colorants comprising naphthalimide base groups with specific water-solubilizing pendant moieties attached. These pendant moieties are based upon aryloxypolyoxyalkylene groups which provide the desired solubility to the naphthalimide colorant compound. Furthermore, the aryloxypolyoxyalkylene groups facilitate the further addition of other pendant groups to the base compound which increase or decrease the solubility of the resultant naphthalimide derivative colorant as well. Such modified naphthalimides are useful as fluorescent colorants, particularly within other liquid media (both aqueous and non-aqueous) without the necessary inclusion of surfactants, solvents, diluents, and the like. Methods of making such colorants, as well as the aryloxypolyoxyallylene intermediates, are also contemplated within this invention.Type: GrantFiled: February 2, 1999Date of Patent: December 7, 1999Assignee: Milliken & CompanyInventor: Robert L. Mahaffey, Jr.

Patent number: 5938828Abstract: This invention relates to solid complexes of anionic organic dyes with quaternary ammonium compounds which have average molecular weights of below about 900 which are substantially free from unwanted salts. Of particular interest as quaternary ammonium compounds are those which comprise alkoxylated moieties. Such complexes are formed through ionic bonds formed between the two compounds. The complexes are then removed of substantially all resultant unwanted salt formed from the cations of the dye and the counter-ions of the quat so as to obtain a solid dyeing agent which easily disperses within different media and which possess extremely good non-migration and coloring characteristics. This invention also concerns methods of making the aforementioned salt-free solid anionic dye/quat complexes as well as methods of utilizing such complexes for dyeing thermoplastic, thermoset, and wax compositions.Type: GrantFiled: April 24, 1998Date of Patent: August 17, 1999Assignee: Milliken & CompanyInventors: Xiaodong Edward Zhao, Kaye Cannon Suddeth, Robert L. Mahaffey, Jr.

Patent number: 5935272Abstract: This invention relates to compositions comprising naphthalimide derivative colorants themselves comprising naphthalimide backbones with specific water-solubilizing pendant moieties attached. These pendant moieties are based upon aryloxypolyoxyalkylene groups which provide the desired solubility to the naphthalimide colorant compound. Furthermore, the aryloxypolyoxyalkylene groups facilitate the further addition of other pendant groups to the base compound which increase or decrease the solubility of the resultant naphthalimide derivative colorant as well. Such modified naphthalimides are useful as fluorescent colorants, particularly for and within other liquid media (such as liquid detergents). The particular types of compositions encompassed within this invention include aqueous and non-aqueous media, such as, without limitation, liquid detergents, hard surface cleaners, fabric softeners, light duty liquid cleaning compositions, paint strippers, cleaning solvents, and the like.Type: GrantFiled: February 2, 1999Date of Patent: August 10, 1999Assignee: Milliken & CompanyInventors: Robert L.

Naphthalimide colorants with improved compatibility in refrigeration and air conditioning lubricants
Patent number: 5918269Abstract: Novel naphthalimide-derivative colorants are provided which are present in a neat liquid state at ambient temperature and pressure. Such colorants are produced through the reaction between 4-chloro (or bromo)-1,8 naphthalic anhydride and at least one etheramine, at least one branched alkylamine, or mixtures thereof. The inventive colorants are excellent leak detection agents for refrigeration and air conditioning systems. These naphthalimide derivatives are completely miscible in all different types of standard refrigeration and air conditioning lubricants. Furthermore, since these colorants are liquid, they are not susceptible to crystallizing within such systems. Thus, the inventive naphthalimide leak detecting agents cannot cause the failure of such machinery due to the crystallization of colorant and subsequent clogging of system compressors. Methods of making and using such inventive naphthalimide-derivative colorants are also disclosed.Type: GrantFiled: February 18, 1998Date of Patent: June 29, 1999Assignee: Milliken & CompanyInventor: Robert L. Mahaffey, Jr. -
