Aqueous dispersion of copolymers formed by the polymerization of a monomer mixture containing 0.05% to less than 4.5% by weight of certain terminally unsaturated oligomers are useful for improving the scrub resistance, corrosion resistance, opacifying capacity and/or efflorescence resistance of a coating.

Aqueous composition

A method of crosslinking an oxidative polymer having oxidatively crosslinkable functional groups and a two-pack composition used therein. The oxidatively crosslinkable functional groups on the oxidative polymer are crosslinked by contacting the oxidative polymer with a catalytic amount of an oxidizing enzyme, such as horseradish peroxidase. The present invention is further directed to a two-pack coating composition which includes a polymeric component and a catalytic component, which are mixed together prior to use.

High temperature polymerization process and products therefrom

The present invention is directed to producing a luminescent screen used in a cathode ray tube (CRT) suitable for monochromatic or chromatic images, such as, those utilized in televisions, computers or data monitoring equipment, which require CRTs. The method of the present invention produces an ablative layer of the luminescent screen having a smooth surface with reduced surface distortions, such as, streaks and waviness, which are typically produced by conventional coating processes. When a reflective aluminum film is deposited on such a smooth ablative layer, the reflective aluminum film is also provided with a smooth surface, since it typically conforms to the underlying smooth surface of the ablative layer. As a result, CRT images having reduced distortions are produced. The method of the present invention further provides for enhancing the brightness of CRT images, which results from utilizing low ash producing polymers in the ablative layer and the binder of a luminophor layer of the luminescent screen. The method of the present invention further provides for combining the step for volatilizing of the ablative layer and the binder in the luminophor layer with the step for cementing of the face plate of CRT with the cone of CRT, without adversely affecting the quality of the hermitic seal between the face plate and the cone.

Detergent and dispersant compositions from high temperature

The present invention relates to fast drying waterborne printing inks and to method of using such inks in high speed printing processes, such rotogravure and flexographic printing processes. The printing ink includes, for example, a blend of a latex binder and a polyfunctional amine. The pH of the ink is raised by adding a sufficient amount of base, to a point where essentially all of the polyfunctional amine in the blend is in a deprotonated state.

The composition having wet state clarity includes an aqueous latex binder combination of polymer particles with a diameter of less than 80 nanometers and a thickener. When glitter flakes are dispersed in these novel compositions in their wet state, they glitter more than conventional glitter compositions. Thus, they are more appealing to a consumer or an artist than conventional glitter compositions that tend to be cloudy or dull in their wet state.
