A redispersible or soluble product, optionally having a solids content higher than 10% by weight, obtainable by freeze drying an aqueous dispersion of a latex comprising a polyanion and a polymer or copolymer of a substituted or unsubstituted thiophene; a printing ink comprising the above product; a coating dispersion or solution comprising the above product; and a method for making an antistatic or electroconductive layer comprising the steps of: redispersing or diluting the above product by adding water or an organic solvent so as to obtain a dispersion or solution; optionally adding other ingredients to the coating solution or dispersion; and applying the dispersion or solution to an object.
摘要:
An antistatic polymer film having a coated surface that resists the formation of static. The antistatic coating on the film layer includes a polythiophene, a surfactant and water. The ratio of the surfactant to the polythiophene can be at least about 1:1 by weight of said coating. In addition, the coating can contain less than about 1 percent by weight of polymeric binder and can also contain less than about 1 percent by weight of organic solvent.
摘要:
Phenolic aralkylation polymers modified by esterification with fatty acids, transesterification with glyceride oils, or other modifications to reactive hydroxyl moieties to improve the characteristics and properties of coating systems in which the modified materials are incorporated. At least a portion of the hydroxyl moieties of the polyol is esterified or otherwise modified. The hydroxyl moieties include those that have been 'chain-extended', if desired.

The invention pertains to a coating composition comprising a polyacetoacetate and a crosslinker for said polyacetoacetate wherein the crosslinker is present in an amount insufficient to crosslink all acetoacetate groups and the polyacetoacetate has a number average molecular weight less than 1000. The coating composition may also comprise an organosilane. The organosilane preferably comprises at least one amino group, amino-containing group, epoxy group, epoxy-containing group, mercapto group, mercapto-containing group, vinyl group, vinyl-containing group, isocyanate group, isocyanate-containing group, ureido group, ureido-containing group, imidazole group or imidazole-containing group. The coating composition is particularly useful as a primer for an aluminium substrate.
