The present invention relates to aqueous binders and to heat-sealing lacquers produced therefrom for heat-sealable coatings which adhere on aluminium without use of any primer, permit good sealability of the coated aluminium foil with respect to PS and/or PVC, and moreover feature good blocking resistance even at temperatures above 40&#xb0; C.

Aqueous binders for heat-sealing applications

The present invention relates to aqueous binders and to heat-sealing lacquers produced therefrom for heat-sealable coatings which adhere on aluminum without use of any primer, permit good sealability of the coated aluminum foil with respect to PS and/or PVC, and moreover feature good blocking resistance even at temperatures above 40&#xb0; C.

The invention discloses a gastric resistant pharmaceutical or nutraceutical composition, comprising a core, comprising a pharmaceutical or nutraceutical active ingredient and a gastric resistant coating layer onto the core, wherein the gastric resistant coating layer comprises at least 30% by weight of a (meth)acrylate copolymer comprising polymerized units of 10 to 40% by weight of acrylic or methacrylic acid, 10 to 80% by weight of a C- to C-alkyl ester of acrylic or methacrylic acid and optionally 0 to 60% by weight of another vinylic monomer, whereby the release of the pharmaceutical or nutraceutical active ingredient is not more than 10% under in-vitro conditions at pH 1.2 after 2 hours in medium according to USP with and without the addition of 20% (v/v) ethanol.

Gastric resistant pharmaceutical or nutraceutical composition with resistance against the influence of ethanol

A plastisol formulation which can be used for coatings of metal sheets, the coatings having high abrasion resistance, contains a) a plasticizer or mixture of plasticizers; and b) a mixture of polymer particles containing at least two components A and B; c) at least one member selected from the group consisting of fillers, coupling agents, stabilizers, desiccants, rheological additives, hollow bodies and mixtures thereof; wherein the polymer particles containing at least two components A and B have one of the following structures ba) a 2-stage structure, a 3-stage structure or multi-stage structure, or bb) a gradient polymer structure.

Method for synthesis of spray-dried poly(METH)acrylate polymers, use of same as polymer components for plastisols, and plastisols produced therewith
