Abstract:
Provided is a laminate film having excellent bonding properties, resistance to water whitening, and chemical resistance. The laminate film is provided with a fluororesin layer (I) comprising a fluororesin composition (A), and an acrylic resin layer (II) comprising a resin composition (B) that contains a reactive group-containing acrylic resin (B-1), wherein (B) contains, with respect to a total of 100 wt% of (B-1), acrylic rubber particles (B-2), and a thermoplastic resin (B-3) having a mass-average molecular weight of less than 400,000, 10-100 mass% of (B-1), 0-90 mass% of (B-2), and 0-90 mass% of (B-3); the film contains an additive (C) at a level of 0-50 mass parts with respect to a total of 100 mass parts of (B-1) to (B-3); and (B-1) contains monomer units having substituent groups that are reactive with amino groups or methylol groups, and the content of the monomer units is 4 mass% or greater with respect to 100 mass% of (B).
Abstract:
The present invention relates to a high strength polyester fiber for a seat belt, and in particular, to a polyester fiber for a seat belt having intrinsic viscosity of 0.8 to 1.5 dl/g, tensile strength of 8.8 g/d or more, and total fineness of 400 to 1800 denier, and a method of preparing the same. As the polyester fiber of the present invention includes filaments having high strength, low modulus, and high elongation to significantly lower shrinkage, while securing excellent mechanical properties, a seat belt having excellent impact absorption and significantly improved abrasion resistance and heat resistant strength retention may be manufactured even with a woven density of 260 yarns/inch or less.
Abstract:
The present invention provides a system for fabricating a microneedle device and microneedle devices. The system includes depositing a first material on a delivery sheet, introducing the delivery sheet with deposited first material to a mold, passing the delivery sheet with deposited first material and mold through a nip-point to introduce at least a portion of first material into cavities in the mold, and separating the mold from the first material to provide a microneedle device with needles mimicking the cavities of the mold.
Abstract:
An imprinting method for forming a pattern of a cured product by irradiating a curable composition for imprinting disposed on a substrate with light while the curable composition is in contact with a mold having surface asperities and removing the mold from a cured product of the curable composition. The method includes bringing the mold into contact with the curable composition in a condensable gas atmosphere, wherein the curable composition for imprinting has a viscosity in the range of 1 cP to 40 cP in air at 23° C., and the condensable gas is introduced between the mold and the curable composition such that the curable composition for imprinting has a condensable gas solubility (gas/(curable composition+gas)) (g/g) in the range of 0.1 to 0.4.
Abstract:
The present invention has an object of providing a synthetic resin laminate that is usable for a transparent substrate material or protective material, has high thermoformability (pressure formability, thermal-bending formability), high insert moldability, and high surface hardness and/or impact resistance, and also providing a molded body formed by molding such a synthetic resin laminate. The synthetic resin laminate includes a polycarbonate-based substrate layer; and a resin laminated on one of, or both of, two surfaces of the polycarbonate-based substrate layer, the resin containing a specific (meth)acrylate copolymer resin and a specific polycarbonate resin. The polycarbonate-based substrate layer includes a polymer alloy and thus has a glass transition temperature (Tg) of 110 to 130°C. Thus, the resultant synthetic resin laminate has high thermoformability and high surface hardness.
