Abstract: Provided is a cyclic olefin-based resin composition including a cyclic olefin-based polymer (A), and a hindered amine compound (Y) that contains a piperidyl group represented by General Formula (1) and a carboxylic acid amide group represented by General Formula (2) within the same molecule.

Abstract: A resin composition for forming an optical component contains (A) a cyclic olefin-based polymer and (B) one or a plurality of coloring agents. The cyclic olefin-based polymer (A) includes at least one selected from a copolymer of ethylene or an ?-olefin with a cyclic olefin, and a ring-opening polymer of a cyclic olefin. A molded product having a thickness at which transmittance of light having a wavelength of 700 nm is 30%, which is formed of the resin composition, satisfies all of the following conditions (1) to (3): (1) an average value of transmittance at a wavelength of 300 to 400 nm is equal to or less than 40%, (2) an average value of transmittance at a wavelength of 500 to 600 nm is equal to or more than 70%, and (3) transmittance at a wavelength of 650 nm is equal to or more than 60%.

Abstract: Provided is a resin composition for forming an optical component, the resin composition including a cyclic olefin-based polymer and an anthraquinone-based dye, in which the cyclic olefin-based polymer includes at least one selected from a copolymer of ethylene or an ?-olefin and a cyclic olefin, and a ring-opening polymer of a cyclic olefin.

Abstract: Disclosed is a graft-modified syndiotactic propylene polymer having a high graft ratio. Also disclosed are a method for producing such a polymer, a resin composition containing such a polymer, and a laminate having at least one layer which contains the composition as an adhesive resin composition. Specifically disclosed is a graft-modified syndiotactic propylene polymer which is characterized by satisfying the following characteristics [1]-[3]. [1] The melt flow rate (MFR) measured at 230° C. under a load of 2.16 kg is 30-1000 (g/10 minutes). [2] The concentration of graft groups derived from a radically polymerizable unsaturated compound by 1H-NMR measurement is within the range of 0.7-7.0% by weight. [3] The syndiotactic pentad fraction determined by 13C-NMR measurement is not less than 0.80.
