    Abstract: The present invention provides an ultraviolet curable composition including: an urethane resin having a polymerizable unsaturated group, which is obtained by reacting a polyol and a polyisocyanate with each other, wherein the polyol contains an alkylene diol having two or more polymerizable unsaturated groups, which is represented by general formula (1), or an oxyalkylene diol having two or more polymerizable unsaturated groups, which is represented by general formula (2); an aqueous medium; and a photopolymerization initiator having an absorption peak at a wavelength in the range of from 320 to 460 nm. The ultraviolet curable composition is satisfactorily cured even when using an LED lamp as a light source, and can form a cured coating film having both elongation and surface hardness. €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ HO-R 1 -OH €ƒ€ƒ€ƒ€ƒ€ƒ (1) €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ HO-R 1 O-R 2 -OR 3 -OH €ƒ€ƒ€ƒ€ƒ€ƒ (2)

    Abstract: Provided are a method for producing a polyvinyl alcohol resin which is highly transparent in the form of an aqueous solution, has a good appearance when formed into a film or an aqueous gel, and improves ink acceptability and color appearance and exhibits water resistance when used for a thermal recording material or an ink-jet recording material; and a polyvinyl alcohol resin obtained by the method. In particular, provided is a method for producing a polyvinyl alcohol resin, comprising the steps of copolymerizing an aliphatic vinyl ester (A) with diacetone acrylamide (B), at least a part of which diacetone acrylamide (B) is added at a later stage, in the presence of a polymerization catalyst in an alcohol solvent, so that the ratio (a)/(b) of the polymerization yield at the end of the polymerization (a) to the polymerization yield at the end of the later addition (b) of diacetone acrylamide (B) is in the range of 1.01 to 1.10, and saponifying the resulting copolymer.

    Abstract: Two-part aqueous coating compositions as well as methods of using thereof are described. The first coating component can comprise one or more polymers and the second coating component can comprise a flocculant. The first coating component and the second coating component can be provided as separate aqueous compositions. The first coating component and a second coating component that can be co-applied (e.g., simultaneously or sequentially) to a surface form a rapid set coating.
