Publication number: 20140275319Abstract: Provided is an active-energy-radiation-curable inkjet recording ink that experiences reduced repulsion when ejected onto nonabsorbent substrates, that has good curability, and that causes little color mixing between uncured coatings formed adjacent to each other by ejecting inks and can thus form fine images on nonabsorbent substrates. The present invention provides an active-energy-radiation-curable inkjet recording ink containing a pigment, a silicone acrylate, an active-energy-radiation-curable compound other than the silicone acrylate, and a radical polymerization initiator. The silicone acrylate is a particular organically modified silicone acrylate including a side chain containing a polyoxyalkylene having a (meth)acryloyl group at an end thereof. The active-energy-radiation-curable compound is a compound (E) having a (meth)acryloyl group and a vinyl ether group.Type: ApplicationFiled: October 26, 2012Publication date: September 18, 2014Applicant: DIC CORPORATIONInventors: Tomokazu Yamada, Yuichi Chisaka, Kazunari Kawai, Yoshitaka Kiuchi

Publication number: 20140128495Abstract: A method for the preparation of an organic-inorganic hybrid composition is performed through three major steps. In addition, a product is generated from this organic-inorganic hybrid composition. In step one, a series of hydrolysis reactions and condensation reactions with a functional organosilane or a combination of functional organosilanes, in presence of water as a reactant for hydrolysis and a suitable acid or a base as a catalyst is performed in order to obtain the first intermediate. In step two, a hydroxyl group-capping intermediate is prepared via reacting a hydroxyl reactable chemical with a hydroxyl functional polymerizable compound. In the third step, a hydroxyl group-capping reaction is conducted with the first intermediate and the hydroxyl group-capping intermediate, so as to obtain the organic-inorganic hybrid composition. It may further include a polymerization step to form an organic-inorganic hybrid polymer composition by UV irradiation or other approaches.Type: ApplicationFiled: November 8, 2013Publication date: May 8, 2014Applicant: NEW SITECH LLCInventors: Zhikai WANG, John Jun CHIAO
