Abstract: This photocurable resin composition contains a polymer cross-linked material (A) and a polymeric material (B), wherein the polymer cross-linked material (A) contains urethane(meth)acrylate, and the polymeric material (B) contains a polyurethane resin that includes a structure derived from polycarbonate polyols and that does not have an acrylic group. This photocurable resin composition has excellent high-temperature adhesion. The urethane(meth)acrylate in the polymer cross-linked material (A) preferably includes a structure derived from polycarbonate polyols.

Abstract: The invention relates to an aqueous polyurethane resin dispersion having a good dispersibility in an aqueous medium and capable of forming a paint film excellent in strength when cured by ultraviolet light, and an aqueous polyurethane resin dispersion excellent in drying property, having a high hardness and being capable of providing a paint film having a scratch resistance, wherein the polyurethane resin is obtained by reacting at least a polycarbonate polyol (a); an acidic group-containing polyol (b); and an optional polyol (c) other than (a) and (b), with a polyisocyanate (d), and optionally further reacting with a chain extender (B), as well as a paint composition and a coating agent composition containing the same, and a preparation process of the same.

Abstract: Disclosed are a polyurethane resin aqueous dispersion of, as dispersed in an aqueous medium, a polyurethane resin obtained through reaction of a polycarbonate polyol (a) at least having a recurring unit represented by the following formula (1) and a polyisocyanate compound (d), and a method for producing the polyurethane resin aqueous dispersion. (wherein Z1 and Z2 each independently represent a divalent aliphatic hydrocarbon group having from 1 to 10 carbon atoms and optionally having a substituent).

Abstract: Disclosed is a commercially suitable method for producing a 1-substituted-5-acylimidazole compound. A 1-substituted-5-acylimidazole compound is produced with a high position selectivity by reacting an N-substituted amidine compound or a salt thereof with a ketone compound in the presence of a base.

Abstract: A task of the present invention is to provide a method for preparing a dispersion liquid comprising liquid crystal-compatible particles and a paste thereof, which is commercially advantageous in that a dispersion liquid comprising liquid crystal-compatible particles and a uniform liquid crystal-compatible particle paste can be obtained using a method which can easily achieve mass-production.
