Appl. No.:

6/068369

Inventors:

Robert F. Farmer - Rockville MD
Phillip E. Sokol - late of Rockville MD

Assignee:

The Gillette Company - Boston MA

International Classification:

A61K 706

US Classification:

424 70

Abstract:

This invention deals with novel sulfated copolymers of hydroxyethyl methacrylate and alkyl esters of acrylic acid and sulfated copolymers of hydroxyethyl acrylate and alkyl esters of methacrylic acid. The copolymers are useful as components in aqueous hair shampoo systems to provide an after-shampoo conditioning effect.

Filed:

Nov 30, 1977

Appl. No.:

5/855947

Inventors:

Robert F. Farmer - Rockville MD
Phillip E. Sokol - Rockville MD

Assignee:

The Gillette Company - Boston MA

International Classification:

B43K 500
C09D 1100

US Classification:

106 22

Abstract:

Ink compositions for use in capillary type writing instruments containing quaternary ammonium of the formula: RCH. sub. 2 N(CH. sub. 3). sub. 3. sup. + X. sup. - wherein R is --CH. sub. 2 OH or --COOH, and X is --OH, --Cl, --Br, or --I. These ink compositions, when used in capillary type writing instruments, allow rejuvenation of writing points which have dried out from exposure to the atmosphere.

Filed:

Nov 5, 1981

Appl. No.:

6/318307

Inventors:

Robert F. Farmer - Rockville MD

Assignee:

The Gillette Company - Boston MA

International Classification:

C09D 1118
C08K 501
C08L 5300

US Classification:

523161

Abstract:

An erasable ink containing a thermoplastic block copolymer, pigment particles, and a solvent. In a preferred embodiment, an erasable ink requiring little or no pressurization is provided by employing a mixture of radial and linear block copolymers and a mixed solvent system falling within a specific range of solubility parameter. Polybutene and poly-alpha-methylstyrene are preferred additives to decrease smearing tendency.

Appl. No.:

5/706206

Assignee:

Alcolac Inc. - Baltimore MD

International Classification:

C08L 3314

US Classification:

260 296SQ

Abstract:

Novel copolymerizable esters of cinnamic acid or an. omega. -alkenoic acid of from 4 to 18 carbon atoms, such as undecylenic acid, with certain hydroxyalkane sulfonic acids, such as isethionic acid, are described together with processes of making them and copolymers thereof. These novel copolymerizable esters may be made by reaction of the. omega. -alkenoic or cinnamic acid with the hydroxyalkane sulfonic acid or a sultone, such as propane sultone. These novel ester are useful as copolymerizable surfactants in the emulsion polymerization of ethylenically unsaturated monomers; particularly for the production of self-stabilizing latices of polymeric materials possessing excellent mechanical stability and from which can be deposited films having improved adhesion, pigment wetting and bonding properties and greatly improved resistance to water. They are also useful as comonomers for the production of polymeric materials having sulfonic acid functionality, such as polyelectrolyte materials based on acrylonitrile, vinyl chloride, vinyl acetate, acrylates, methacrylates, styrene, etc. ; for example, when used as a comonomer in the production of fibers and films based on the above monomers, they impart improved dye receptivity and anti-static properties to the polymeric fibers and films so made.

Robert F. Farmer - Gaithersburg MD

Assignee:

The Gillette Company - Boston MA

International Classification:

B32D 3500

US Classification:

427140

Abstract:

This invention relates to materials and methods used in informational, testing, educational, amusement and other paper-based feedback systems embodying invisible images comprising a color-forming reactant material which can be rendered temporarily visible by the application of a coreactant. The systems may also include visible printed images and are suitable for multiple reuse.

Assignee:

The Gillette Company - Boston MA

International Classification:

C11D 112
C11D 183

US Classification:

252545

Abstract:

This invention deals with novel sulfated condensation products of ethylene oxide with bases formed by condensing propylene oxide with propylene glycol, and having a molecular weight of about 11. phi. phi. to 48. phi. phi.
