  • Patent number: 10016787
    Abstract: In a method for forming a multilayer coated film including an intermediate coated film, a base coated film, a clear coated film and an adhesive layer, an intermediate coating composition (X) contains a hydroxyl group-containing polyester resin (A), a melamine resin (B), a pyrazole-blocked polyisocyanate compound (C), a pigment (D), and an organic solvent (E), a content ratio (B/C) is from 5/35 to 20/15 in terms of solid content ratio, and a concentration (PWC) of the pigment (D) is from 40% to 60%. The cured intermediate coated film has, at 20° C., an elongation at break of 40% to 90%, a Young's modulus of 600 MPa to 1,600 MPa, and a Tukon hardness of 3 to 9.

  • Publication number: 20100324271
    Abstract: It is an object of the present invention to provide antibodies which recognize non-reducing mannose residues. The present invention provides antibodies recognizing non-reducing mannose residues, which are obtained through screening of phage-display library of human scFvs by using, as an antigen, Man3-DPPE which is an artificial glycolipid synthesized from mannotriose and dipalmitoylphosphatidylethanolamine by reductive amination.
