  • Publication number: 20220282019
    Abstract: The present invention has an object to provide a modified polyolefin resin capable of forming a coating film that is excellent in water-resistant adhesiveness under a high temperature condition. The present invention provides a modified polyolefin resin including a graft-modified product in which a component (A) that is a polyolefin resin is graft-modified with a component (B) that is an ?, ?-unsaturated carboxylic acid or a derivative thereof, and having a tensile modulus of 250 MPa or higher, and a weight-average molecular weight of 70,000 or more and less than 200,000.

  • Patent number: 11390211
    Abstract: A light bar mounted on a steering wheel includes a holding member, a substrate, a plurality of visible light sources, a plurality of infrared light sources, and a light guiding element. The holding member includes a radiating opening. The substrate is held by the holding member in such a manner that a gap is formed between a first end in a width direction of the substrate and one of side walls of the holding member. The infrared light sources are mounted and arranged on a front surface of the substrate generally along a length direction of the substrate for emitting infrared light toward the driver. The visible light sources are mounted and arranged on a back surface of the substrate generally along the length direction of the substrate. The light guiding element is configured to deflect visible light emitted from the visible light sources toward the radiating opening.

  • Publication number: 20220186014
    Abstract: An object is to provide a dispersion resin composition which can maintain dispersion stability even if the added amount of an emulsifier is reduced. Provided is a dispersion resin composition including, at least: a modified polyolefin resin in which a modification component containing an ?,?-unsaturated carboxylic acid derivative with a ring structure has been introduced to a polyolefin resin; and an aqueous dispersion medium, wherein the modified polyolefin resin has a degree of ring opening, represented by the equation (1), of 70 or more: degree of ring opening=modification degree K√órate of ring opening R ??(1) (in the equation (1), the modification degree K represents a containing rate (% by weight) of the ?,?-unsaturated carboxylic acid derivative relative to the polyolefin resin, and the rate of ring opening R represents a rate of ring opening (%) of the ring structure in the ?,?-unsaturated carboxylic acid derivative).

  • Publication number: 20210221926
    Abstract: A modified polyolefin resin is described. The modified polyolefin resin can enhance a cleaning property upon cleaning inside of a coating machine with a cleaning solvent including water, and is excellent in a balance between heat resistance and solution stability. The modified polyolefin resin is a polyolefin resin that is modified with an ?,?-unsaturated carboxylic acid or a derivative thereof and with an amino alcohol having a primary or a secondary amino group.
