Disclosed are compounds of formula (I) wherein R1, R2, R5 and R6 are as defined in the claims; such compounds have interesting pharmacological properties.
A responsive microgel is provided which responds volumetrically and reversibly to a change in one or more aqueous conditions selected from the group consisting of (temperature, pH, and ionic conditions) comprised of an ionizable network of covalently cross-linked homopolymeric ionizable monomers wherein the ionizable network is covalently attached to an amphiphilic copolymer to form a plurality of ‘dangling chains’ and wherein the ‘dangling chains’ of amphiphilic copolymer form immobile micelle-like aggregates in aqueous solution. A responsive microgel is further provided that comprises at least one therapeutic entity and delivers a substantially linear and sustained release of the therapeutic entity under physiological conditions.

(EN) A coated sheet material (22) made by: (a) coating a porous substrate sheet (10) with a barrier coating composition comprising (i) a cross-linkable polymer resistant to penetration by water moisture, and (ii) a water-dispersible film-forming polymer that is resistant to penetration by grease and oil, said barrier coating composition forming a barrier layer (14) on said susbtrate sheet material; and (b) coating said barrier layer with a release coating composition (16). The coated sheet material is useful in forming articles and food wrappers for use in conventional or microwave ovens. The invention includes methods of making articles from the coated sheet materials.(FR) Une feuille (22) portant un revêtement est faite: (a) par application à une feuille de substrat poreuse (10) d'une composition de revêtement constituant une barrière, comprenant (i) un polymère réticulable résistant à la pénétration de l'humidité de l'eau et (ii) un polymère que l'on peut disperser dans l'eau et qui est capable de former un film résistant à la pénétration des graisses et des huiles, ladite composition de revêtement formant une couche barrière (14) sur ladite feuille de substrat; et (b) par application sur cette couche barrière d'une composition anti-adhésion (16). La feuille avec son revêtement est utile pour former des articles et des emballages destinés à être utilisés dans des fours conventionnels ou à micro-ondes. L'invention concerne également des procédés pour fabriquer des articles faits en une feuille portant le revêtement en question.
