  • Bed sheet set with different thermal properties
    Publication number: 20050268399
    Abstract: The bed sheet set with two or more bed sections with different thermal properties for occupants who share the bed and desire to sleep with bedding having different thermal properties. The invention includes a top bed sheet and a bottom bed sheet divided into two adjacent bed sections made of thin and thick cotton, respectively. In the preferred embodiment, the two bed sections are longitudinally aligned and sewn together along the sheets' longitudinal center axis. The top sheet includes a decorative inside surface and a transversely aligned decorative band, which provides an attractive edge when the top bed sheet is partially folded over. The top and bottom bed sheets are made of cotton, polyester or nylon that can be frequently laundered and changed like normal cotton bed sheets.

  • Hair dye compositions and methods utilizing 2-substituted-1-naphthol couplers
    Patent number: 5344463
    Abstract: 2-substituted-1-naphthols when coupled with an oxidation dye precursor in an oxidative dye system produce a long lasting intense color to hair. Use of such couplers makes available to the colorist novel oxidation hair dyes which surprisingly show a color shift to the red. Dyestuffs prepared through use of the 2-substituted-1-naphthol couplers are substantially more acid-fast compared to like dyestuffs using a 1-naphthol coupler. Compositions and a method of dyeing hair are also disclosed.
