Abstract: Disclosed is a photocurable resin composition for nanoimprint, containing a curable monomer component with or without a binder resin. The composition further contains 0.001 to 5 parts by weight of a compound having a reactive functional group and a hydrophobic functional group in the same molecular skeleton, per 100 parts by weight of the total amount of the curable monomer component and binder resin. Preferably, the reactive functional group is at least one functional group selected from the group consisting of hydroxyl groups, epoxy groups, vinyl ether groups, oxetanyl groups, alkoxysilane groups, and free-radically polymerizable vinyl groups, and the hydrophobic functional group is at least one functional group selected from the group consisting of fluorine-containing groups, alkylsilane groups, alicyclic hydrocarbon groups, and aliphatic hydrocarbon groups having 4 or more carbon atoms.

Abstract: Disclosed is a process for the production of a fine structure through nanoimprinting a photocurable resin composition. The process includes the steps of (1) forming a photocurable resin composition for nanoimprint into a film on a support and transferring a pattern to the film by pressing the film with a nanostamper at a pressure of 5 to 100 MPa, in which the photocurable resin composition contains a curable compound component including at least one cationically polymerizable compound and/or at least one free-radically polymerizable compound; and (2) curing the patterned film to obtain the fine structure.

Abstract: The present invention relates to a process for producing a curing agent for a polyurethane paint, which comprises an aliphatic or alicyclic diisocyanate and a polyester polyol, wherein the polyester polyol is a copolymerized lactone polyol obtained by a ring-opening copolymerization of at least two members of cyclic lactone compounds each represented by the following formula (I) in the presence of a low molecular weight compound having at least two active hydrogen groups as an initiator. By using at least two members of cyclic lactone compounds, there is provided a curing agent for a polyurethane paint which is capable of forming a paint film having high mechanical strength, particularly high flexibility or impact resistance under low temperatures, and excellent in gloss retention.

Abstract: The present invention provides a process for producing a polyurethane foam, which comprises allowing an organic polyisocyanate component to react with a polyol component in the presence of a catalyst with water as a foaming agent, wherein the polyol component comprises at least 30% by weight of a copolymerized lactone polyol having a hydroxyl value of 20 to 350 KOHmg/g and being in the form of a liquid at an ordinary temperature, the copolymerized lactone polyol is obtained by ring opening copolymerization of ?-caprolactone and ?-valerolactone in a molar ratio [?-caprolactone/?-valerolactone] of 80/20 to 20/80 with a low molecular weight compound having at least two active hydrogen groups as an initiator; and the hydroxyl value of the polyol component is 40 to 400 KOHmg/g.

Abstract: The reaction of a vinyl monomer (A), an unsaturated fatty acid hydroxyalkyl ester-modified polycaprolactone (B) and a radical polymerization initiator (I) in a continuously mixing reactor can provide a crosslinkable vinyl polymer (C) having a number average molecular weight of about 500 to about 10,000. A cured product thereof has a high elasticity and a high strength, and finds many applications, for example, paints, coating materials, adhesives and pressure-sensitive adhesives.

Abstract: A molded article is produced from a flame retardant resin composition obtained by compounding a thermoplastic resin or thermosetting resin with a flame retardant composition comprising as essential ingredients a fluorine compound (A) represented by the following formula (1): R1—SO2—R2 or R1—SO3?M+??(1) (wherein R1 represents a C1-C12 perfluoroalkyl group, a C2-C8 perfluoroalkenyl group, a C6-C12 perfluoroaryl group which may be substituted, a C3-C12 perfluoroalicyclic hydrocarbon group, or a C7-C12 perfluoroaralkyl group; R2 represents a halogen atom, an N-alkylamino group, or an N-alkyl-N-hydroxyalkylamino group; and M represents an alkali metal) and a polyester resin (B). The molded article has flame retardancy despite addition of the fluorine compound (A) in a very small amount. Excellent dispersion of the fluorine compound (A) is attained, and bleeding of the compound (A) is prevented.

Abstract: A gas generator for an air bag that can change the inflating (deploying) speed of the air bag is provided. The gas generator includes a vessel having a pressurized gas accommodation chamber for accommodating pressurized gas therein, a partition that divides the pressurized gas accommodation chamber into two sections, and a through-hole which is defined in the partition, for communicating the two sections. The gas generator also includes two ignition units containing gas generating agents therein, and a gas release unit disposed in the pressurized gas accommodation chamber and having a rupturable gas sealing wall. A single ignition unit can be disposed in each section or two ignition units can be disposed in one of the two sections.
