摘要:
The purpose of the present invention is to provide an extreme pressure agent which does not contain any metal element or the like and is highly safe but which exhibits performance equivalent to those of conventional extreme pressure agents each containing a metal element or the like when used in lubrication purposes. This extreme pressure agent comprises a copolymer (A) which comprises an alkyl acrylate (a) represented by general formula (1) and a hydroxyalkyl acrylate (b) represented by general formula (2) as the essential constituent monomers, and is characterized in that the reaction ratio of the component (a) to the component (b) (i.e., (a)/(b)) is 50/50 to 80/20 (by mole) and the copolymer (A) has a weight average molecular weight of 40,000-150,000. (In formula (1), R1 represents an alkyl group having 10-18 carbon atoms.) (In formula (2), R2 represents an alkylene group having 2-4 carbon atoms.) (in the formula, R 1 represents an alkyl group having 10 to 18 carbon atoms) (in the formula, R 2 represents an alkylene group having 2 to 4 carbon atoms).
摘要:
A composition comprising both a polymer which contains triazine-ring-containing repeating units represented by formula (17) and a crosslinking agent which consists of either a poly-functional epoxy compound or a polyfunctional (meth)acrylic compound can be photo-cured even without the addition of an initiator to yield a cured film having a high refractive index and high heat resistance. Thus, a photocurable film-forming composition that comprises a triazine-ring-containing polymer, which can achieve, even without the addition of a metal oxide by the polymer alone, high heat resistance, high transparency, a high refractive index, high solubility and low volume shrinkage, and that is curable even without the addition of an acid generator can be provided.

An object of the present invention is to provide an ink composition for inkjet recording that is excellent in terms of surface gloss and storage stability. Disclosed is an ink composition for inkjet recording comprising (Component A) a polymerizable compound, (Component B-1) an oxyl free radical-based polymerization inhibitor, (Component B-2) a phenol-based polymerization inhibitor, and (Component B-3) an amine-based polymerization inhibitor. The polymerizable compound (Component A) preferably comprises (Component A-1) a divinyl ether compound. The ink composition preferably further comprises (Component C) a polymerization initiator, and more preferably comprises (Component C-1) an acylphosphine-based polymerization initiator as the polymerization initiator (Component C).
摘要:
An adhesive film, an adhesive composition for the same, and an optical member including the same are disclosed. The adhesive composition includes a (meth)acrylate copolymer having carbonate groups and an aromatic groups. The adhesive film can be used to attach transparent members to each other, inhibit variation in capacitance, prevent malfunction due to touching, and improve outdoor visibility in a capacitive touch panel.
摘要:
An object of the present invention is to provide a filler for ion-exchange liquid chromatography which can effectively suppress non-specific adsorption of protein and the like, a method for analyzing glycosylated hemoglobin using the filler for ion-exchange liquid chromatography, a method for production of a filler for ion-exchange liquid chromatography that can maintain suppressive effects on swelling, non-specific adsorption and the like for a long period of time. The method of production of the filler comprises a hydrophilization process by washing the surface of the filler particle with ozone water having a dissolved ozone gas concentration of 20 ppm or more and by either setting the pH of the ozone water to 7 or more and applying ultrasound, or by irradiation with UV light.
摘要:
