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.

Method for dispersing optical brighteners in waterborne coating

Disclosed is a water-dissipatable or dispersible adhesive composition that is useful in forming paper articles and other products that can be recycled through repulping in both neutral and alkaline media. The water-dispersible adhesive composition is preferably a hot melt adhesive that is a low molecular weight, branched copolyester containing a sulfomonomer. Additional utility for the invention resides in the manufacture of recyclable articles where insolubility in body fluids combined with solubility in tap water are required.

Ink compositions and preparation

In a process for printing a substrate employing apparatus elements such as printing plates, engraved rolls, wiping blades, transfer rolls, metering rolls, or the like, and printing ink which comes into contact with the elements and substrate, the improvement comprising carrying out the printing with an ink comprising an aqueous system of colorant and water dispersible polymer having carbonyloxy linking groups in the linear molecular structure wherein up to 80% of the linking groups may be carbonylamido linking groups, the polymer having an inherent viscosity of at least about 0.1 measured in a 60/40 parts by weight solution of phenol/tetrachloroethane at 25.degree. C. and at a concentration of about 0.25 gram of polymer in 100 ml. of the solvent, allowing the ink to substantially dry, and subsequently contacting the dried ink with a solution of one or more multivalent cation salts to impart thereto a high degree of resistance to water dispersibility.
