摘要： This invention provides a method for rendering a water-based coating (i.e., one which contains essentially no organic solvent) fluorescent. Also provided is a method for measuring the extent of coverage and thickness of a water-based coating by incorporating therein a minor amount of an emulsion of an insoluble compound which absorbs ultraviolet light and fluoresces strongly in the visible region of the spectrum, so that the intensity of the fluorescence serves as an indication of the degree of coverage and thickness of the film. Also provided is a method for enhancing the apparent brightness of a film pigmented with light colored pigments. In the case where white pigments such as titanium dioxide are used, the effect is to increase the apparent whiteness of the film.

摘要： A hypoallergenic adhesive article employing a switchable pressure sensitive adhesive (PSA) composition comprising one or more amphiphilic polyesters in physical mixture with a humectant. When contacted with a liquid of low-ion content, the adhesive undergoes a reduction in peel strength, which allows for easy removal, but remains strongly adhered when contacted with ionic liquids, such as blood, sweat, and other bodily fluids. The adhesive composition can be employed in a variety of medical articles or in other similar applications.

摘要： The present invention provides improved adhesion promoters for latex paints. The adhesion promoters are enamines of acetoacetate esters, or substituted acetoacetate esters. The invention also provides two new compounds which are useful as adhesion promoters: 2-butyl-2-ethyl-1,3-propanediol bis(3-amino-2-butenoate) and trimethyl propane tris(3-amino-2-butenoate), and which are stable to hydrolysis on prolonged storage.
