Abstract: The invention relates to hair care compositions comprising an effective amount of a condensation polymer having at least one, optionally quarternized or protonated, dialkylamide end-group connected through the polymer backbone to a unit derived from an alkylamide, the connection comprising at least one ester linkage.

Abstract: The invention relates to novel optionally quaternized or protonated condensation polymers having at least one heterocyclic end-group connected to the polymer backbone through a unit derived from an alkylamide, the connection comprising an optionally substituted ethylene group and to the use thereof in body care products and household products.

Abstract: The invention relates to photoresist composition suitable for use at 10-165 nm comprising: (a) a polymeric binder (b) a photoactive compound (c) a dissolution inhibitor, the dissolution inhibitor comprising at least (i) two aromatic groups, (ii) fluorine and (iii) a blocked acid group which when unblocked has a pKa<12. Preferred dissolution inhibitors are optionally blocked bisphenol derivates in which the bridging carbon atom is substituted with a fluorinated aliphatic group.
