  • Publication number: 20030091834
    Abstract: A coated plastic molding having a final coating on a molding body formed of plastic material and having elastic modulus in tension of from about 10 to about 2,000 MPa. The coated plastic molding has such a relationship that a ratio E′/E is 0.5 or more when the elastic modulus in tension of the molding body is E and the elastic modulus in tension of the final coating is E′.

  • Patent number: 5938881
    Abstract: A decorative sheet is obtained by a process which comprises superimposing a reinforcing plate, a second hot melt adhesive sheet, a porous decorating sheet, a third transparent hot melt adhesive sheet, and a transparent film in sequence on a first hot melt adhesive sheet, and then subjecting the laminate to heat pressing. The decorative sheet is then inserted into the mold. A base resin is then injected onto the back side of the first adhesive sheet of the decorative sheet.

  • Patent number: 5910427
    Abstract: Antigen non-specific human glycosylation inhibiting factor derivatives having the inmunosuppressive activity in which a mutation was introduced for replacement, deletion and/or insertion of a part of the amino acid sequence of SEQ ID NO:21, and/or which has received a chemical modification of one or more amino acid residue(s) in the amino acid sequence of SEQ ID NO:21, wherein the mutation and the chemical modification attenuate the strength of an intermolecular association in the region, which participates in trimerization, of an antigen non-specific human glycosylation inhibiting factor having the amino acid sequence of SEQ ID NO:21; DNAs containing a base sequence encoding the amino acid sequence of the antigen non-specific human glycosylation inhibiting factor derivative; recombinant vectors containing the DNAs; prokaryotic or eukaryotic cells transformed with the DNAs; methods of producing the antigen non-specific human glycosylation inhibiting factor derivatives; pharmaceutical compositions comprising t

  • Patent number: 5833916
    Abstract: A molded article containing an outer decorative film and a support, and a method and composition for making the same are disclosed. The outer film has a decorative layer and a protective layer, the protective layer being formed from a photopolymerizable resin composition. In an uncured state, the composition includes (a) an acrylic copolymer containing a backbone and at least one side chain linked to the backbone, the at least one side group having at least one (meth)acryloyl group, the backbone having a glass transition temperature of about 40.degree. C. to about 120.degree. C. and a weight-average molecular weight of about 10,000 to about 200,000; (b) a compound other than the copolymer (a), the compound having at least three (meth)acryloyl groups; and a photopolymerization initiator. The at least one (meth)acryloyl group is preferably linked to the backbone by a reacted glycidyl group.

  • Patent number: 5736247
    Abstract: A coated molded article including a body of an olefin resin and finish coat of an acrylic urethane resin paint, the paint includes a modified acrylic polyol resin produced by copolymerizing an acrylic resin with a polar group-introduced polyolefin and an acrylic polyol resin. Particularly, coated molded articles of an olefin resin can be used as exterior components for automobiles (e.g. side molding, bumper, wheel cap, etc,), as well as exterior components for buildings. These exterior components are required to have physical properties as article such as weather resistance, abrasion resistance and the like, while maintaining an attractive appearance.
