The disclosure relates to an organic-inorganic hybrid (OIH) polymeric composition and related methods for forming the same. The disclosure also relates to a polymeric composition as disclosed herein and related methods for forming the same. The OIH polymeric composition and the polymeric composition can be formed by UV-irradiating a corresponding composition including a Michael-addition (MA) acceptor compound, a Michael-addition (MA) donor compound, a silane compound, when present, and a photo-latent base initiator to form a corresponding base catalyst and catalyze the reactions forming the networked polymer. The OIH polymeric composition and the polymeric composition can be used as a coating on any of a variety of substrates or as an interlayer in an additive manufacturing process.

A polysiloxane-substituted quinacridone pigment is produced by a quinacridone pigment with an epoxy-terminated polysiloxane under conditions effective to cause the epoxy group on the polysiloxane to react with, and bond the polysiloxane to, the quinacridone pigment. The quinacridone pigment thus produced has the polysiloxane grouping bonded to one of the quinacridone nitrogen atoms via a hydrocarbon linking group, which bears a hydroxyl group on a carbon atom α or β to the quinacridone nitrogen atom. These quinacridone pigments are useful in electrophoretic displays.
