  • Polyester resin, hot melt adhesive, and hot melt adhesive solution
    Patent number: 9951258
    Abstract: The polyester resin for a hot melt adhesive includes polycarboxylic acid residues and polyhydric alcohol residues. The polycarboxylic acid resides contain aliphatic polycarboxylic acid residues in a proportion within the range of 50 to 80 mol %. The polyhydric alcohol residues contain propylene glycol residues in a proportion within the range 5 to 60 mol %.
    Type: Grant
    Filed: July 30, 2013
    Date of Patent: April 24, 2018
    Assignee: GOO CHEMICAL CO., LTD.
    Inventors: Teru Sakakibara, Koji Maeda, Yusuke Numamoto
  • Hybrid-type polyester resin, resin composition for formation of film, and polyester film and textile
    Patent number: 9873978
    Abstract: Provided is a hybrid-type polyester resin which, when used in processing a base material such as textile or PET film, can impart excellent flame retardance to the base material. The hybrid-type polyester resin can be inhibited from scattering high-temperature drips, even if the hybrid-type polyester resin burns. The hybrid-type polyester resin comprises both a polyester resin and a siloxane prepared from silica and an alkoxysilane. Therefore, the hybrid-type polyester resin retains the excellent properties inherent in polyester resin and exhibits extremely excellent flame retardance by virtue of hybridization with the siloxane. Even if the hybrid-type polyester resin burns, the hybrid-type polyester resin is less susceptible to deformation, and is therefore inhibited from scattering high-temperature drips.
