Inventor: SEITZ MICHAEL E A
IPC: C09D11/02
Filed: 1991-09-10
Abstract: A high solids content, aqueous, microcapsule-containing printing ink is prepared by forming microcapsules in situ in a printing ink vehicle. The microcapsules are preferably prepared by interfacial polymerization or interfacial crosslinking between a reactant, such as a polyisocyanate dissolved in an oily solution and a coreactant such as a polysalt of casein and diethylene triamine present in an aqueous solution into which the oily solution is dispersed. The aqueous solution contains water and preferrably a non-volatile diluent such as a non-reducing sugar, for example methyl glucoside. The oil-containing microcapsules contain an oil solvent and a mixture of dye precursors which upon reaction with a color developer produces an intense black image. The printing ink preferably has a 60-70% by weight solids content and may be used as a low-coat-weight CB coating for preparing carbonless copy paper.

Title: Light-duty dishwashing detergent composition containing an alkyl ethoxy carboxylate surfactant and calcium ions
Inventor: OFOSU-ASANTE KOFI
IPC: C11D7/10
Filed: 1991-11-06
Abstract: A light-duty liquid or gel dishwashing detergent composition containing  an  alkyl  ethoxy  carboxylate  surfactant  mixture  and calcium ions. The composition may require a calcium chelating agent, particularly at pH levels above 9, to prevent the formation of CaCO3 precipitates during storage.
