Abstract: The use of a boric acid, borate or derivate and/or salt thereof in a subbing layer coated onto a non resin-coated support beneath an upper layer comprising a binder and an inorganic particulate material such as fumed silica and an under layer between the upper layer and the subbing layer, which under layer comprises a binder and an inorganic particulate material such as calcium carbonate, increases the gloss of an ink jet receiver formed thereby whilst maintaining good ink absorption, good image density and minimizing puddling and associated coalescence, and where the receiver otherwise suffers from surface-cracking, decreases the propensity to cracking.
Abstract: The present invention is directed to an image-recording medium comprising a paper support and, coated on one side of the support, in order: a lower ink-receiving layer, an upper gloss layer and, coated on the opposite side of the support, an inner layer comprising at least 75% by weight of fine inorganic particles and a binder, and an outer layer substantially consisting of a polymeric material. Another aspect of the present invention relates to an inkjet printing process.

Abstract: The present invention discloses a method of making core-shell polymer particles, comprising forming a linking-group-containing polymer by derivatizing a hydroxy-group-containing polymer, comprising hydroxy groups on adjacent carbon atoms with a linking agent, that is a compound comprising both an aldehyde moiety and an amine moiety, wherein one or more acetal moieties are formed in the linking-group-containing polymer, each acetal formed by the reaction of the aldehyde moiety in the linking agent with two hydroxy groups in the linking-group-containing polymer, wherein the amine moiety then becomes a linking group pendent from the linking-group-containing polymer, wherein the linking group is capable of reacting with a precursor group in the precursor polymer. Also disclosed are compositions comprising insoluble core-shell particles made by the method.
